Chilled Closed Water Loop

There are several different designs for HVAC machines even though they all operate on the same basic principles. A chilled closed water loop circulates from the HVAC machine through large air handling units in open spaces and fan coils in individual rooms. Fans are run to blow over these coils and the chilled water absorbs heat. This process effectively cools the air. The warm water will flow back through the HVAC machine to start the process again.

Chilled Closed water loop servicing

There is a common misconception that closed cooling and heating systems require less maintenances and service attention when compared to other open cooling systems. This common misconception is based on the fact that closed systems operate routinely and the water is not visible. This is completely untrue.

Closed HVAC systems operate as the primary contact point for air in climate control systems, and they provide direct cooling of data processing equipment and process machinery. If proper water treatment programs and maintenance servicing is not carried out, the consequences could be catastrophic. These problems can sometimes occur quickly without much warning.

Chemenergy will prevent the following from occurring in your chilled closed loop system:

- Loss of water quality & Purity
- Loss of flow- Water losses
- Dissolved oxygen 
- Microbiological problems / contamination 
- "Free cooling" operational problems from carry over water from cooling tower to loop
- Mineral scaling- Suspended matter
- Corrosion- MIC corrosion
- Pitting corrosion
- Loss of system efficiency
- Higher utility bills
-Higher natural resource consumption

Chemenergy can eliminate and offer prevention programs of operating and water-realted problems that can occur in your closed chilled water loop system. We provide services & solutions for "Free cooling" set-ups where the cooling tower water is used for the loop water. These set-ups require even more care and focus that only a dedicated team of professionals can give you.
