Comfort control system for all conventional pumps in glandless and glanded design with fixed speeds and three-phase motors.

For continuous power adjustment to the variable operating states of single-, dual- or multi-pump systems (up to 6 pumps). Controlling depends on the differential pressure Δp, feed/return temperature (±T) or differential temperature (ΔT), including the free adjustment of the duty point by means of advance correction of the full-load pump output.

How it works

Wilo Comfort Control Systems enable the infinitely variable electronically controlled power adjustment of pumps to the variable operating statuses of the hydraulic system, depending on the pressure (p), volume flow (Q) and temperature (T) control variables.
