Precise Temperature and Humidity Control Range

Precise Control Unit

Air Change Precise Control Units manage both temperature and humidity at close tolerances.  The variable DX cooling and free re-heat operating principle allows for high efficiency, along with reduced installation complexity compared to that of conventional desiccant systems.  Precise Control Units are engineered to meet project specific requirements and design conditions, allowing for high versatility in terms of application.

Air Change PCU – Precise temperature and humidity control for any application.
