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.

Benefits

  • Energy saving through the control of ΔT in the system.
  • Provides optimal efficiency for chillers and boilers.
  • By reducing the required flow to achieve the system ΔT, additional flow capacity can be released.
  • Simple installation between the BMS and the 0-10VDC modulating actuator.
  • Quick and simple to set up.
  • Can be easily retrofitted to an existing system.

Key features

  • Easy to use buttons for setting the optimum ΔT set point.
  • Automatically detects whether the Control System is installed in a heating or cooling system.
  • Temperature sensors can be mounted on a varity of pipe dimensions from DN15 to DN300.
  • To avoid starving the coil of flow the DELTA T Control System is programmed so it never sends a voltage signal to the actuator of less than 1.5V. This means that the DELTA T Control System does not close the valve fully even if the measured ΔT is below the set point. The BMS can always close the valve if the signal sent is less than 1.5V.
  • 0-10V DC feedback signal for monitoring the terminal unit operation.
