Actuators for Chilled Water Valve - These chilled water actuators control the flow rate for a chilled water system in a data center. There are various sequences of operations for chilled water systems and the sequence of operations is usually always different from one chiller plant to another chiller plant. (more…)
Rooftop Economizer CO2 | HVAC Control – This damper is part of a free cooling system for a rooftop economizer. It is part of an economizer damper system that allows free outside air cooling when the outside air temperature and humidity are ideal. This economizer also works on CO2 control so that if the CO2 levels inside the space rise above a set point the economizer damper opens allowing fresh outside air into the building while venting the air laden with CO2 to the outside.

Plate Heat Exchanger and Free Cooling - This plate heat exchanger is used in a data center for a chilled water system and is a chilled water economizer. Heat exchangers are used in marine applications, industrial processes including chemical processing systems, food processing, and many HVAC applications including chilled water applications, hot water applications, and economizer applications.
