ACUMER™ 3100 terpolymer contains three functional groups: strong acid (sulfonate), weak acid (carboxylate) and a nonionic that provide optimal dispersancy for most particules under

a broad range of operating conditions:

• ACUMER 3100 carboxylate groups are most strongly attracted to particles surfaces, allowing strong dispersant absorption onto particles.

• ACUMER 3100 sulfonate groups are only weakly attracted to the particle surface and retain some residual negative charge to provide repulsion preventing particles from

aggregating into larger particles which can settle and deposit on tube surfaces and low flow areas.

• ACUMER 3100 nonionic groups further enhance dispersancy by providing steric repulsion between particles.

Dispersancy

Performance

ACUMER™ 3100 polymer is an exceptional dispersant, especially for dispersing both dried and hydrated iron oxide, hydroxyapatite and calcium carbonate. It is also an excellent

stabilizer for corrosion inhibitors such as phosphate, phosphonates and zinc.

Suggested

Applications

• Dispersant and stabilizer that can be used in cooling water programs ACUMER 3100 terpolymer excels in harsh cooling water conditions, such as extremely

high or low Ryznar Indexes, high iron concentrations, high levels of zinc or phosphate added as treatment to the system. ACUMER 3100 is particularly recommended in

advanced all-organic programs. The product can maintain excellent heat transfer by its exceptional dispersancy and, in addition, will help corrosion inhibition by controlling film

formation of the organic corrosion inhibitors onto metal surfaces.

• Control of boiler sludge

ACUMER 3100 terpolymer is the product of choice for boiler water treatment formulations as it provides unsurpassed control of boiler sludge. The polymer makes it possible to

easily transport iron with calcium and phosphate containing sludges for removal during blowdown. Superior iron oxide dispersant, ACUMER 3100 is particularly recommended to

control hydrated iron oxide in condensate return line.

Thermal/Hydrolytic

Stability

ACUMER™ 3100 terpolymer is highly resistant to breakdown in aqueous solution under conditions of high temperature, pressure and pH. As a safety measure ACUMER 3100 is

not recommended for boilers operating at pressure greater than 900 psig. ACUMER 3100 is very resistant to hydrolysis as well. The product does not lose its

performance capability after storage at pH 13.5 for 6 months at ambient temperature. Approval ACUMER™ 3100 is TUV approved for use in boilers under the reference: 06-KG-66

ACUMER 3100 Terpolymer

The Anti-Scale Deposition for

“Stressed” Cooling Water Conditions

ACUMER 3100 is a carboxylate/sulfonate/nonionic functional terpolymer. It is a superior dispersant and

stabilizer for use in all cooling water programs. When other polymers fail under “stressed” conditions,

ACUMER 3100 will maintain excellent heat transfer and low corrosion rates in the system. “Stressed” conditions are found in cooling waters containing high levels of calcium, iron, phosphate, or zinc either, naturally occurring in the feedwater or introduced via treatment. These circulating waters may have either a very

low or a very high Ryznar Index since ACUMER 3100 performs well in waters with either a scaling or corrosion problem. It is an excellent anti-scalant agent and, also, a stabilizer for corrosion inhibitors such as

phosphate and zinc.

ACUMER 3100 will disperse particulate matter containing calcium, iron, and kaolin and prevent their adhesion to heat transfer surfaces. This terpolymer also prevents the precipitation of phosphonates, and zinc

in circulating water with high amounts of calcium, iron, or alkalinity, to allow controlled film formation of these corrosion inhibitors at the metal surface and, thus, maintain low corrosion rates.

CHEMISTRY AND MECHANISM OF ACTION

ACUMER 3100 terpolymer contains three functional groups: strong acid (sulfonate), weak acid (carboxylate), and a nonionic that provide optimal dispersancy for most particulates under a broad range of operating conditions.

Among the three functionalities, ACUMER 3100 carboxylate groups are most strongly attracted to particle surfaces, allowing strong dispersant adsorption onto particles. ACUMER 3100 sulfonate groups are only

weakly attracted to the particle surface and retain some residual negative charge to provide repulsion of similarly charged particles in the cooling water circuit. This repulsion prevents particles from aggregating into

larger particles which can settle and deposit on tube surfaces and low flow areas. ACUMER 3100 nonionic groups further enhance dispersancy by providing steric repulsion between particles.

This multi-functional action contrasts sharply to other dispersants, such as polyacrylic acid or polymethacrylic acid, having only carboxylate functionality which can become strongly attached to certain particles, leaving little residual negative charge available to provide dispersancy. Other polymers, such as SSMA

can provide better dispersancy than PAA or PMAA on some particle substrates, but do not have the nonionic group which allows ACUMER 3100 terpolymer to function on a broader range of potential foulants.

It excels in the harshest of cooling water conditions, such as extremely high or low Ryznar Indexes, high iron concentrations, high levels of zinc or phosphate added as treatment to the system. ACUMER 3100 (akumer 3100) (akümer 3100) is particularly recommended in advanced all-organic programs. The product will maintain excellent heat transfer by its superior dispersancy and, in addition, will help corrosion inhibition by controlling film formation of the organic corrosion inhibitors onto metal surfaces.

Control of boiler sludge

ACUMER 3100 (akumer 3100) (akümer 3100) terpolymer is the product of choice for boiler water treatment formulations as it provides unsurpassed control of boiler sludge. The polymer makes it possible to easily transport iron with calcium and phosphate containing sludges for removal during blowdown. Superior iron oxide dispersant, ACUMER 3100 (akumer 3100) (akümer 3100) is particularly recommended to control hydrated iron oxide in condensate return line.

Thermal/Hydrolytic Stability

ACUMER 3100 (akumer 3100) (akümer 3100) is very resistant to hydrolysis as well. The product does not lose its performance capability after storage at pH 13.5 for 6 months at ambient temperature.

ACUMER 3100 (akumer 3100) (akümer 3100) Terpolymer

The Anti-Scale Deposition for

“Stressed” Cooling Water Conditions

ACUMER 3100 (akumer 3100) (akümer 3100) is a carboxylate/sulfonate/nonionic functional terpolymer. It is a superior dispersant and

stabilizer for use in all cooling water programs. When other polymers fail under “stressed” conditions,

ACUMER 3100 (akumer 3100) (akümer 3100) will maintain excellent heat transfer and low corrosion rates in the system. “Stressed” conditions are found in cooling waters containing high levels of calcium, iron, phosphate, or zinc either, naturally occurring in the feedwater or introduced via treatment. These circulating waters may have either a very low or a very high Ryznar Index since ACUMER 3100 (akumer 3100) (akümer 3100) performs well in waters with either a scaling or corrosion problem. It is an excellent anti-scalant agent and, also, a stabilizer for corrosion inhibitors such as

phosphate and zinc.

ACUMER 3100 (akumer 3100) (akümer 3100) will disperse particulate matter containing calcium, iron, and kaolin and prevent their adhesion to heat transfer surfaces. This terpolymer also prevents the precipitation of phosphonates, and zinc in circulating water with high amounts of calcium, iron, or alkalinity, to allow controlled film formation of these corrosion inhibitors at the metal surface and, thus, maintain low corrosion rates.

CHEMISTRY AND MECHANISM OF ACTION

ACUMER 3100 (akumer 3100) (akümer 3100) terpolymer contains three functional groups: strong acid (sulfonate), weak acid (carboxylate), and a nonionic that provide optimal dispersancy for most particulates under a broad range of operating conditions. Among the three functionalities, ACUMER 3100 (akumer 3100) (akümer 3100) carboxylate groups are most strongly attracted to particle surfaces, allowing strong dispersant adsorption onto particles. ACUMER 3100 (akumer 3100) (akümer 3100) sulfonate groups are only weakly attracted to the particle surface and retain some residual negative charge to provide repulsion of similarly charged particles in the cooling water circuit. This repulsion prevents particles from aggregating into larger particles which can settle and deposit on tube surfaces and low flow areas. ACUMER 3100 (akumer 3100) (akümer 3100) nonionic groups further enhance dispersancy by providing steric repulsion between particles. This multi-functional action contrasts sharply to other dispersants, such as polyacrylic acid or polymethacrylic acid, having only carboxylate functionality which can become strongly attached to certain particles, leaving little residual negative charge available to provide dispersancy. Other polymers, such as SSMA can provide better dispersancy than PAA or PMAA on some particle substrates, but do not have the nonionic group which allows ACUMER 3100 (akumer 3100) (akümer 3100) terpolymer to function on a broader range of potential foulants.

DISPERSANCY PERFORMANCE of ACUMER 3100 (akumer 3100) (akümer 3100)

ACUMER 3100 (akumer 3100) (akümer 3100) terpolymer outperforms polymaleic acid and competitive polymers under cooling water conditions.

All-Organic Program

ALL-ORGANIC cooling water treatments rely on high pH (8-9) and high alkalinity (>200 ppm, as CaCO3) to help passivate metal surfaces. Organic phosphonate is used to inhibit CaCO3 precipitation and forms a cathodic corrosion-inhibiting film of calcium phosphonate. A “yellow-metal” inhibitor, such as tolyltriazole, is frequently included to inhibit brass or copper corrosion. Polymers, such as ACUMER 3100 (akumer 3100) (akümer 3100), are used to disperse particulates, inhibit CaCO3 precipitation, and stabilize calcium phosphonate. ACUMER 3100 (akumer 3100) (akümer 3100) stands out as the superior polymer for this program. Figure 5 shows results from phosphonate stabilization tests which demonstrate the superiority of ACUMER 3100 (akumer 3100) (akümer 3100).

Pigment concentrates have always been a modern and flexible way to produce colored paints. Especially in waterborne applications, these concentrates have to be suitable for a broad range of different binder technologies. Because of that, the concentrate formulations are usually free of binders and offer a broad compatibility. Furthermore, the demands in terms of storage stability, color strength and cost efficiency are very high. These demands are addressed directly to the additive technology. The additive is expected to provide outstanding viscosity reduction in order to achieve high pigment loadings and the most economic grind. It has to stabilize the viscosity over long periods of time and has to develop maximum color strength to avoid underutilizing any expensive pigments. Iron oxides are the most important pigment class when it comes to decorative coatings. The difficulty in iron oxides lies in the shape and not the wetting of the pigment. Iron oxide yellow tends to give dilatant rheology, which can be a disaster when automatically dosing in a dispensing machine. On the other hand, iron oxide red tends to increase in viscosity over time in pigment concentrates.

Thermal/Hydrolytic Stability of ACUMER 3100 (akumer 3100) (akümer 3100)

ACUMER 3100 (akumer 3100) (akümer 3100) is very resistant to hydrolysis as well. The product does not lose its performance capability after storage at pH 13.5 for 6 months at ambient temperature.

Results: The system treated with ACUMER 3100 (akumer 3100) (akümer 3100) polymer achieved more than 4.5 cycles of concentration with no silica drop-out. Early in this trial, the chemical feed was stopped accidentally; a subsequent drop in recirculating water SiO2 levels suggests that some scaling probably occurred. When the chemical feed was re-established, SiO2 levels temporarily increased to higher than expected levels, which leads to the conclusion that the ACUMER 3100 (akumer 3100) (akümer 3100) polymer had removed some of the scale. This also suggests that the dispersing action of the polymer, even when underfed, resulted in the formation of a powdery scale rather than the expected glassy magnesium silicate. The powdery nature of the scale would explain its apparent on-line removal. Data showed that over 200 ppm SiO2 had been attained in the recirculating water. Winery Increases Silica in Cooling Water Past Vintage Levels of 150 ppm SiO2 System A northern California vineyard operates two 560-ton evaporative condensers using

Descripion: makeup water1 with high silica levels of 92 ppm SiO2. The cooling water system has a capacity of 18 gallons per minute with water temperatures ranging between 75°F (24°C) and 85°F (29°C).

Problem: Initially, a stabilized phosphate program containing HEDP, phosphoric acid, tolyltriazole and an acrylate-type polymer was used. Scale formed on the evaporative condensers when silica levels exceeded 150 ppm SiO2 in the recirculating water. This deposit was found to contain high levels of silicon and magnesium.

Results: Our customer replaced the existing polymer in his formulation with ACUMER 3100 (akumer 3100) (akümer 3100) polymer. This formulation was dosed into the system to maintain 13 ppm residual orthophosphate and 10-15 ppm active ACUMER 3100 (akumer 3100) (akümer 3100) polymer in the recirculating water. The recirculating water contains 400 ppm M-Alkalinity and had a pH between 8.5 and 8.7. The customer was able to increase cooling water cycles from 1.6 to 3 COC allowing up to 276 ppm SiO2 in the system. Thorough visual inspections, after 2 and 5 months, condenser tubes were free of scale. By switching to ACUMER 3100 (akumer 3100) (akümer 3100) polymer, this customer was able to cut his chemical usage by almost half and save 4 million gallons of water per year. 1 Make-up water analysis: pH 7.8, 138 ppm T-Alkalinity, 92 ppm SiO2, 35 ppm Ca as CaCO3, 11 ppm Mg, 7.4 ppm SO4, 18 ppm Cl, <0.1 ppm Fe, <0.3 ppm Mn, 270 ppm TDS. Cooling System Doubles COC in San Joaquin Valley, California System Two evaporative condenser towers rated at 500 tons were used to cool a large computer

Description: computer facility. One tower was always kept as a backup to ensure continuous operation. The evaporative condensers consist of rows of tubes on the inside of the tower.

The tower water cascades downward to directly contact the condenser tubes leaving a scale deposit if the water significantly exceeds the normal operating levels of about 180 ppm SiO2 and about 480 ppm (maximum) M-alkalinity. The original treatment used HEDP, benzotriazole and polymaleic acid with a supplemental feed of polyacrylic acid. Problem: The makeup water typically had 90-110 ppm SiO2, allowing only about 2 cycles of concentration. Due to severe drought conditions in this area for the previous 5 years, water was not readily available and had to be reused to the maximum extent possible. Solution: In 1991, the polymaleic acid and polyacrylic acid scale inhibitors used in the old treatment were replaced with an equal weight of ACUMER 3100 (akumer 3100) (akümer 3100) polymer. The treatment was fed to maintain the same levels as before, but the bleedoff was reduced.

Results: With ACUMER 3100 (akumer 3100) (akümer 3100) polymer, the system maintained up to about 4 cycles of concentration without scale or corrosion. Recirculation water has up to 300 ppm total silica and about 650 ppm M-alkalinity (maximum). Benefits of the reduction in bleedoff include:

• A calculated 30% reduction in water usage under typical conditions.

• A calculated 30% reduction in chemical usage.

• An increase in holding time which allows the biocide to work more

effectively (since the makeup water has a high organism count).

Chimie et mode d’action

Le terpolymère ACUMER 3100 (akumer 3100) (akümer 3100) contient trois groupes fonctionnels: un acide fort (sulfonate), un acide faible (carboxylate) et un non ionique qui offrent une dispersance optimale pour la plupart des particules dans une large gamme de conditions de fonctionnement:

Les groupes carboxylates sont les plus fortement attirés par les surfaces des particules, permettant une forte absorption du dispersant sur les particules.

Ses groupes sulfonates ne sont que faiblement attirés vers la surface des particules et conservent une certaine charge négative résiduelle pour fournir une répulsion empêchant les particules de s’agréger en particules plus grosses qui peuvent se déposer et se déposer sur les surfaces des tubes et les zones à faible débit.

Ses groupes non ioniques améliorent encore la dispersibilité en fournissant une répulsion stérique entre les particules.

Performances de dispersion

C’est un dispersant exceptionnel, bien supérieur aux autres types de polymères, en particulier pour disperser à la fois l’oxyde de fer, l’hydroxyapatite et le carbonate de calcium séchés et hydratés. C’est également un excellent stabilisant pour les inhibiteurs de corrosion tels que le phosphate, les phosphonates et le zinc.

Applications de l’ACUMER 3100 (akumer 3100) (akümer 3100)

Dispersant et stabilisant à utiliser dans tous les programmes d’eau de refroidissement

Il excelle dans les conditions d’eau de refroidissement les plus difficiles, telles que les indices Ryznar extrêmement élevés ou faibles, les concentrations élevées de fer, les niveaux élevés de zinc ou de phosphate ajoutés comme traitement au système. ACUMER 3100 (akumer 3100) (akümer 3100) est particulièrement recommandé dans les programmes entièrement biologiques avancés. Le produit maintiendra un excellent transfert de chaleur grâce à son pouvoir de dispersion supérieur et, en outre, contribuera à l’inhibition de la corrosion en contrôlant la formation de film des inhibiteurs de corrosion organiques sur les surfaces métalliques.

Contrôle des boues de chaudière

Le terpolymère ACUMER 3100 (akumer 3100) (akümer 3100) est le produit de choix pour les formulations de traitement de l’eau de chaudière car il offre un contrôle inégalé des boues de chaudière. Le polymère permet de transporter facilement le fer avec des boues contenant du calcium et du phosphate pour son élimination lors de la purge. Dispersant d’oxyde de fer supérieur, l’ACUMER 3100 (akumer 3100) (akümer 3100) est particulièrement recommandé pour contrôler l’oxyde de fer hydraté dans la conduite de retour de condensat.

stabilisateur à utiliser dans tous les programmes d’eau de refroidissement. Lorsque d’autres polymères échouent dans des conditions «stressées»,

ACUMER 3100 (akumer 3100) (akümer 3100) maintiendra un excellent transfert de chaleur et de faibles taux de corrosion dans le système. Des conditions «stressées» se retrouvent dans les eaux de refroidissement contenant des niveaux élevés de calcium, de fer, de phosphate ou de zinc, soit naturellement présents dans l’eau d’alimentation, soit introduits par traitement. Ces eaux en circulation peuvent avoir un indice Ryznar très bas ou très élevé, car l’ACUMER 3100 (akumer 3100) (akümer 3100) fonctionne bien dans les eaux présentant un problème d’entartrage ou de corrosion.

phosphate et zinc.

ACUMER 3100 (akumer 3100) (akümer 3100) dispersera les particules contenant du calcium, du fer et du kaolin et empêchera leur adhérence aux surfaces de transfert de chaleur. Ce terpolymère empêche également la précipitation des phosphonates et du zinc dans l’eau en circulation avec des quantités élevées de calcium, de fer ou d’alcalinité, pour permettre la formation de film contrôlée de ces inhibiteurs de corrosion à la surface du métal et, ainsi, maintenir de faibles taux de corrosion.

CHIMIE ET MÉCANISME D’ACTION

Le terpolymère ACUMER 3100 (akumer 3100) (akümer 3100) contient trois groupes fonctionnels: un acide fort (sulfonate), un acide faible (carboxylate) et un non ionique qui offrent une dispersivité optimale pour la plupart des particules dans une large gamme de conditions de fonctionnement.

Parmi les trois fonctionnalités, les groupes carboxylates ACUMER 3100 (akumer 3100) (akümer 3100) sont les plus fortement attirés par les surfaces des particules, permettant une forte adsorption du dispersant sur les particules. Les groupes sulfonate ACUMER 3100 (akumer 3100) (akümer 3100) ne sont que faiblement attirés vers la surface des particules et conservent une certaine charge négative résiduelle pour fournir une répulsion des particules chargées de manière similaire dans le circuit d’eau de refroidissement. Cette répulsion empêche les particules de s’agréger en particules plus grosses qui peuvent se déposer et se déposer sur les surfaces des tubes et les zones à faible débit. Les groupes non ioniques ACUMER 3100 (akumer 3100) (akümer 3100) améliorent encore la dispersibilité en fournissant une répulsion stérique entre les particules. Cette action multifonctionnelle contraste fortement avec d’autres dispersants, tels que l’acide polyacrylique ou l’acide polyméthacrylique, n’ayant qu’une fonctionnalité carboxylate qui peut devenir fortement attachée à certaines particules, laissant peu de charge négative résiduelle disponible pour fournir un pouvoir dispersant. Autres polymères, tels que SSMA

peut fournir une meilleure dispersion que le PAA ou le PMAA sur certains substrats de particules, mais n’ont pas le non ionique

groupe qui permet au terpolymère ACUMER 3100 (akumer 3100) (akümer 3100) de fonctionner sur une plus large gamme de salissants potentiels.

Un inhibiteur de “métal jaune”, tel que le tolyltriazole, est fréquemment inclus pour inhiber la corrosion du laiton ou du cuivre. Les polymères, tels que l’ACUMER 3100 (akumer 3100) (akümer 3100), sont utilisés pour disperser les particules, inhiber la précipitation du CaCO3 et stabiliser le phosphonate de calcium. ACUMER 3100 (akumer 3100) (akümer 3100) se distingue comme le polymère supérieur pour ce programme.

L’ACUMER 3100 (akumer 3100) (akümer 3100) est un excellent stabilisant de phosphate et de zinc dans les systèmes d’eau de refroidissement stressés et un dispersant supérieur de fer et de boue dans les chaudières.

Les concentrés de pigments ont toujours été un moyen moderne et flexible de produire des peintures colorées. En particulier dans les applications aqueuses, ces concentrés doivent convenir à une large gamme de technologies de liant différentes. Pour cette raison, les formulations concentrées sont généralement exemptes de liants et offrent une large compatibilité. En outre, les exigences en termes de stabilité au stockage, de résistance de la couleur et de rentabilité sont très élevées. Ces demandes s’adressent directement à la technologie additive. On s’attend à ce que l’additif offre une réduction de viscosité exceptionnelle afin d’obtenir des charges de pigment élevées et la mouture la plus économique. Il doit stabiliser la viscosité sur de longues périodes et doit développer une force de couleur maximale pour éviter de sous-utiliser des pigments coûteux. Les oxydes de fer constituent la classe de pigments la plus importante pour les revêtements décoratifs. La difficulté des oxydes de fer réside dans la forme et non dans le mouillage du pigment. L’oxyde de fer jaune a tendance à donner une rhéologie dilatante, ce qui peut être un désastre lors d’un dosage automatique dans une machine de distribution. D’autre part, l’oxyde de fer rouge a tendance à augmenter sa viscosité avec le temps dans les concentrés de pigment.

Chimie et mode d’action de l’ACUMER 3100 (akumer 3100) (akümer 3100)

• Les groupes carboxylates ACUMER 3100 (akumer 3100) (akümer 3100) sont les plus fortement attirés par les surfaces des particules, ce qui permet une forte absorption du dispersant sur les particules.

• Les groupes sulfonates ACUMER 3100 (akumer 3100) (akümer 3100) ne sont que faiblement attirés vers la surface des particules et conservent une certaine charge négative résiduelle pour fournir une répulsion empêchant les particules de s’agréger en particules plus grosses qui peuvent se déposer et se déposer sur les surfaces des tubes et les zones à faible débit.

• Les groupes non ioniques ACUMER 3100 (akumer 3100) (akümer 3100) améliorent encore la dispersibilité en fournissant une répulsion stérique entre les particules.

Résultats: Le système traité avec le polymère ACUMER 3100 (akumer 3100) (akümer 3100) a atteint plus de 4,5 cycles de concentration sans perte de silice. Au début de cet essai, l’alimentation chimique a été interrompue accidentellement; une baisse subséquente des niveaux de SiO2 dans l’eau de recirculation suggère qu’un certain entartrage s’est probablement produit. Lorsque l’alimentation chimique a été rétablie, les niveaux de SiO2 ont temporairement augmenté à des niveaux plus élevés que prévu, ce qui conduit à la conclusion que le polymère ACUMER 3100 (akumer 3100) (akümer 3100) avait éliminé une partie du tartre. Cela suggère également que l’action de dispersion du polymère, même lorsqu’il est sous-alimenté, a conduit à la formation d’un tartre pulvérulent plutôt que du silicate de magnésium vitreux attendu. La nature poudreuse du tartre expliquerait son retrait apparent en ligne. Les données ont montré que plus de 200 ppm de Si02 avaient été atteints dans l’eau de recirculation. La cave augmente la silice dans l’eau de refroidissement au-delà des niveaux vintage de 150 ppm Système SiO2 Un vignoble du nord de la Californie exploite deux condenseurs évaporatifs de 560 tonnes utilisant

Descripion: eau d’appoint1 avec des niveaux élevés de silice de 92 ppm SiO2. Le système d’eau de refroidissement a une capacité de 18 gallons par minute avec des températures de l’eau comprises entre 75 ° F (24 ° C) et 85 ° F (29 ° C).

Problème: Au départ, un programme de phosphate stabilisé contenant du HEDP, de l’acide phosphorique, du tolyltriazole et un polymère de type acrylate a été utilisé. Du tartre s’est formé sur les condenseurs évaporatifs lorsque les niveaux de silice dépassaient 150 ppm de SiO2 dans l’eau de recirculation. Ce dépôt s’est avéré contenir des niveaux élevés de silicium et de magnésium.

Résultats: Notre client a remplacé le polymère existant dans sa formulation par le polymère ACUMER 3100 (akumer 3100) (akümer 3100). Cette formulation a été dosée dans le système pour maintenir 13 ppm d’orthophosphate résiduel et 10 à 15 ppm de polymère actif ACUMER 3100 (akumer 3100) (akümer 3100) dans l’eau de recirculation. L’eau de recirculation contient 400 ppm d’alcalinité M et avait un pH compris entre 8,5 et 8,7. Le client a pu augmenter les cycles d’eau de refroidissement de 1,6 à 3 COC, permettant jusqu’à 276 ppm de SiO2 dans le système. Inspections visuelles approfondies, après 2 et 5 mois, les tubes du condenseur étaient exempts de tartre. En optant pour le polymère ACUMER 3100 (akumer 3100) (akümer 3100), ce client a pu réduire de près de moitié sa consommation de produits chimiques et économiser 4 millions de gallons d’eau par an. 1 Analyse de l’eau d’appoint: pH 7,8, 138 ppm T-alcalinité, 92 ppm SiO2, 35 ppm Ca sous forme de CaCO3, 11 ppm Mg, 7,4 ppm SO4, 18 ppm Cl, <0,1 ppm Fe, <0,3 ppm Mn, 270 ppm TDS. Système de refroidissement double COC dans la vallée de San Joaquin, en Californie Système Deux tours de condenseur par évaporation évaluées à 500 tonnes ont été utilisées pour refroidir un gros ordinateur

Description: installation informatique. Une tour a toujours été conservée comme sauvegarde pour assurer un fonctionnement continu. Les condenseurs évaporatifs sont constitués de rangées de tubes à l’intérieur de la tour.
