Temperature Control Unit (TCU) Modulates Heat Output in Real Time

Delta T Systems says the heart of its new Smart Series TCUs is the Vari-Heat adaptive control engineered to dynamically modulate heat output in real time. By automatically adjusting to system demands and environmental conditions, Delta T says Vari-Heat ensures temperature stability and enhanced energy efficiency. Specifically, the control prevents temperature overshoot for smooth and gradual heating transitions.

The Smart Series TCUs are also Industry 4.0 ready, offering a range of communication options, including remote start/stop and the ability to adjust the temperature set point from any location. The unit logs up to seven days of operational data, giving users insights into system performance.

Ramp and soak recipes enable users to manage temperature variations for more complex processes. Equipped with a flow meter, temperature and pressure sensors, the system continuously monitors performance, issuing high and low warnings and fault notifications.

The Smart Series TCUs also come standard with electronically modulating cooling valves for more accurate flow control than conventional solenoid valves. This valve design also minimizes risks such as undershoot and water hammers.

The TCUs feature a robust double-cast tank design with a maximum heating capacity of 72 kW. The modular design also supports a water-to-water heat exchanger providing future upgrade potential for enhanced cooling needs. Solid-state heater contactors and bimetal switches prevent overheating, and dry-run protection for the pump is available.
