Bacteria Control
Chiller: Corrosion Inhibitors

Chillers require a corrosion inhibitor to prevent excessive corrosion.  Closed Loop Chemical 338 is a Nitrite/Borate/Silicate inhibitor.  Sodium nitrite is an excellent metal passivator and will minimize chiller system corrosion.  Sodium nitrite is a food source for bacteria development, so it is important to monitor the system for bacteria growth if your chiller operates above 45 degrees.

Chiller systems that often operate above 45 degrees should implement a Sodium Molybdate based chemical to minimize system corrosion. Bacteria monitoring is recommended because of the higher water system temperatures.

Bacteria monitoring is recommended for all systems.  Bacteria growth may lead to underdeposit corrosion and localized corrosion pits.  This condition may lead to water leaks and early system failure.  Bacteria that develops as slime may decrease the cooling system heat transfer efficiency and increase your energy costs.

Improper treatment may lead to excessive corrosion.  In this case, excessive iron corrosion may also lead to iron build up on heat transfer areas and decrease the systems efficiency.  This condition will decrease your heat transfer efficiency and may increase your energy costs.

Hot Water and Cooled Water Corrosion Inhibitor
Closed Loop Corrosion Inhibitor - Clear - 5 to 55 Gallons

Closed Loop Chemical 338 is a highly concentrated liquid buffered nitrite/ borate/silicate inhibitor for the treatment of hot and cooled closed water systems. The product is used in both low and high temperature systems as well as low pressure boiler systems with limited makeup water. It may be used with either hard or soft water makeup and is compatible with glycol antifreezes. It is not approved for use in USDA regulated facilities.

One gallon of Closed Loop Chemical 338 treats 100 gallons of water.
Hot Water and Cooled Water Inhibitor Chemical
Closed Loop Corrosion Inhibitor with Red Dye - 5 to 55 Gallons

Closed Loop Chemical 338D is a highly concentrated liquid buffered nitrite/ borate/silicate inhibitor for the treatment of hot and cooled closed water systems. The product is used in both low and high temperature systems as well as low pressure boiler systems with limited makeup water. It may be used with either hard or soft water makeup and is compatible with glycol antifreezes. It is not approved for use in USDA regulated facilities. Closed Loop Chemical 338D contains a P Indicator dye for ease of detection.

One gallon of Closed Loop Chemical 338D treats 100 gallons of water.
Isothiazolin
Isothiazolin - 5 to 55 Gallons

Isothiazolin is an excellent slimicide for use in recirculating cooling water systems. The product is effective over a wide pH range against a wide range of slime forming bacteria typically found in these systems.
Glutaraldehyde
45% Glutaraldehyde - 5 to 55 Gallon Containers

DESCRIPTION AND USE Gluteraldehyde comes in a 45% solution and is considered a highly concentrated microbiocide for use in recirculating cooling water and air washer systems. The product is effective over a wide pH range against slime forming bacteria, sulfate reducing bacteria and fungi. The product functions to kill these microorganisms by reacting with the cell wall. Thus, it possesses many unique features when compared to other materials:

  • Very effective over a broad spectrum of organisms.
  • Aqueous solution which is relatively safe to handle and is easily diluted and mixed when treating.
  • Unlike most non oxidizing biocides, it will function to clean up a biologically fouled system.
  • Functions over wide pH and temperature ranges and will not react with the wide range of inhibitors and anionic dispersants used in modern cooling water treatment.
  •  It is non surface active and therefore will not foam when used. 
CHEMICAL FEEDING AND CONTROL When a system is noticeably fouled, BioGuard 46 should be slug dosed to establish a concentration of 50 to 100ppm actives in the recirculating water (i.e. 4.6 9.2 fl. ozs/100 gals. contained water). Once control is evident, a dosage of 20 to 50ppm (1.8 4.6 fl. ozs/100 gals.) on a weekly basis will normally maintain control unless unusual conditions develop.
