The Frese DELTA T Control System is an easy-to-use solution for measuring, monitoring and optimising the ΔT between the inlet and outlet of a terminal unit, in order to increase the system efficiency and reduce pump energy.
The DELTA T Control System measures and monitors the actual ΔT of the coil.
If the ΔT is equal to or higher than the ΔT set point, the Frese DELTA T Control System will not change the input signal to the actuator and the flow will be according to the BMS input signal.
If the ΔT is lower than the ΔT set point, the Frese DELTA T Control System will lower the input signal to the actuator and thereby decrease the flow through the control valve until the set point ΔT is reached.
The Frese DELTA T Control System can be used in both heating and cooling systems to optimise the inlet and outlet temperature difference of a fan coil unit or air handling unit.
