The Delta T Control system is an innovative solution from Frese, designed as an easy to use control system for measuring, monitoring and controlling temperature difference (?T) between the inlet and outlet of a terminal unit to maximise savings.

Adaptable and versatile, the Delta T Control system can be used as a diagnostic tool as well as a control system to collect and analyse data in both in heating and cooling systems. It can be installed in new build projects, typically with the Frese Optima Compact PICV, or it can be retrofitted to existing valves, without any interruption to the system operation.

How does this work?  Well, poor ?T performance requires additional flow to serve the heating or cooling load which leads to excess equipment being run, loss of capacity, wasted energy and system instability. The Frese Delta T Control System monitors the actual ?T and adjusts the flow through the control valve accordingly, until the ?T of the coil is restored to the minimum set point ?T value.

A decrease in required flow means a decrease in pump energy. By reducing the flow, additional flow capacity is released in the overall system.
