Water Cooled Liquid Chillers by Friulair

The MWC modular chillers and TGR water-cooled thermochillers by Friulair Chillers ensure precise and reliable temperature control. They are designed specifically for environments with high ambient temperatures. 

What Are Water Cooled Chillers and How They Work?

Water-cooled liquid chillers are a highly efficient refrigeration system commonly used in industrial and commercial applications to cool process fluids, spaces, or equipment. Unlike air-cooled chillers, they rely on water and a cooling tower to reject heat, making them ideal for high-capacity cooling and environments where efficiency is a priority.

Compared to air cooled chillers, water-cooled systems are more energy-efficient, particularly in high-capacity applications. The use of a cooling tower reduces the size of the chiller itself, making it easier to fit into mechanical rooms. Furthermore, water cooling is less affected by high ambient temperatures, maintaining efficiency even in warm regions. Water-cooled systems also typically have a longer operational life due to reduced wear and tear from stable operating conditions.

1.     Refrigerant Cycle:

• Heat from the process liquid is absorbed by the refrigerant in the evaporator.
• The refrigerant vapor is compressed to a high temperature and pressure.
• Heat is rejected to the condenser water loop in the condenser.
• The refrigerant is cooled and condensed into a liquid before passing through the expansion valve.

2.     Condenser Water Loop:

• Heated water from the condenser is pumped to the cooling tower.
• The cooling tower uses air and water evaporation to reject heat to the atmosphere.
• Cooled water is returned to the condenser to complete the cycle.

Industry 4.0 Technology: These water cooled chillers are equipped with electronic controllers featuring an RS485 serial communication port and Modbus RTU protocol, allowing for integration with automation systems and remote control for centralized management. For the MWC range, the controller can easily connect in series to the main panel (EVG option) to optimize modular system performance. 

Innovative Software: Each unit is equipped with proprietary software tailored to meet specific application requirements. For the TGR chiller range, Friulair has developed an internal control logic that ensures maximum unit reliability. 

Water-cooled chillers are preferred in hot climates as their efficiency is unaffected by high external air temperatures, unlike air-cooled chillers.
