Calculated control mode

Proportional pressure is used in circulation systems with a pipe system with low pressure loss and control valves to generate a variable flow.

The pressure drop in the control valves is lower than 50 % of the total pressure drop.

• Heating systems with 2-way valves
• Air-con system with 2-way valves

The calculated control mode for proportional pressure is a feature of Grundfos MAGNA3 and TPE3 circulator pumps.
