Chemical treatment for chilled water system

Chiller Water Treatments – the Why and How of Closed Loop. How does a chilled water system works? What is a chilled water circuit? Available Water Treatment Methods.


All activities will be carried out in accordance with the contract details and in full compliance to the project specifications.

All work within the rights-of-way of the standards and specifications will be done in compliance with requirements issued by authorities. Specifically chosen for your conditions, these chemical treatment units automatically control the release of agents into your water to control scale, suspended solids, and microbiological growth in your system. Chemical Treatment Systems. Chilled water treatment chemical reduce the corrosion rates within the chilled water system ? Other chilled water chemicals may include biocides and are added as needed.


Typical heating or cooling systems include three types of loops: a chilled water loop , a refrigerant gas loop and a cooling tower water loop. These types of closed loop systems are susceptible to leaks that can lead to contamination-forming corrosion and bacteria in the cooling water that may ultimately cause a total system failure.

Most chilled water systems incorporate an open recirculating cooling water system with a cooling tower for condenser cooling. Our field engineers have expertise with all associated equipment, including evaporative condensers, shell and tube heat exchangers , plate and frame heat exchangers, etc. Low temperature hot water, closed cooling and chilled water - Mixture of sodium nitrite , borax and molybdate with other copper alloy inhibitor.


Generally, demineralized water is used for closed-loop cooling water makeup, but chemical treatments are required to prevent corrosion an in some systems, freezing. Reliable, Efficient, Field Support. Call Our Expert Team Today! Therefore, the dissolved oxygen is the main reason which causes the corrosion of chilled water system. As the chilled water system runs in a closed circulation for a long time, it will lead to the propagation of anaerobic bacteria which can also corrupt the pipe.


Technological process of chemical dosing system. Therefore, the PMD program for treating closed hot water heating and chilled water systems incorporates attention to these mechanical aspects as well as chemical treatment based on the use of sodium sulfite as an oxygen scavenger. Flushing , and Water Treatment) areprovided by the Water Treatment Supplier (WTS) working directly for the University: 1. Chiller chemicals are used to control corrosion and to prevent bacteria growth. The second chemical is a cooling water biocide.


The most common chiller corrosion chemical is a closed loop nitrite, borate, silicate product. Accepta’s advanced closed loop and closed circuit treatment chemicals have been scientifically formulated to deliver significant operational benefits and performance improvements to heating systems and closed circuit systems including sea water cooling systems , closed chilled systems , low-pressure heating systems and other closed circuits. Accepta’s comprehensive range of high performance cooling water treatment chemicals have been scientifically formulated to deliver significant operational benefits and performance improvements to cooling towers, and open and closed cooling systems that use water as a primary coolant.

POA Corroban 48P is a highly concentrated nitrite based chilled water corrosion inhibitor that can also be used for LTHW and other closed systems incorporating a pink pH indicator. Open systems, such as condenser- water systems, that include a cooling tower require an ongoing program of chemical water treatment. Closed systems typically require only a one-time chemical treatment. Often soft water or condensate is used for make to closed systems depending on the characteristics of the system being protected. Our full service chemical treatment programs for chilled water and hot water closed loops to keep your systems running and maintained.


Boiler Systems Our full service boiler water maintenance program which prevents scale deposits on the water side of the boiler. Sodium chromate has been used for years in closed water systems. Alkaline sodium chromate is an oxidizing agent that functions by forming a dense gamma oxide film on mild steel. A minimum of 3ppm as sodium chromate is required for system protection.


We have with us a good range of specialty chemicals as below.
