The CRE-DP pump is a perfect pump for HVAC applications – a unitized solution that brings together the pump, motor, variable frequency drive and controls to make Energy Optimization of your HVAC pump as easy as possible. The pump features “closed loop control” including proportional differential pressure and constant differential pressure; and “open loop control” from control signal in order for you to optimize your HVAC pumping application.

This control adjust pump performance based on how friction head affects the head requirement needed from the pump. Proportional differential pressure control gives you the ability to simulate a remote mounted DP sensor, whereas constant differential pressure offers the ability to maintain differential pressure across the pump or at a remote remote location or control signal from user or building management system.
