TBW / TWW HeavyDuty

Industrial heat pump module with two compressors in single regrigeration cycle brine - water / water - water

Heat pump module with a pair of compressors connected in single refrigeration cycle on a stable platform that can be placed in the HeavyDuty Modular Heat Heat Pump. Double high-absorption suspension with silicone washers ensures low noise and vibration levels of the hermetic Scroll compressor.

Stainless steel plate heat exchanger (1.4401) for heating circuit. Switchingboard with integrated safety elements and equithermal control of the heat pump is located in a separate cabinet. With electronic starter via built-in soft starter and electronic coolant injection with autoadaptivity.

Frame construction with a massive base plate on adjustable legs. Equithermal, digital control of the heat pump module allowing multi-stage operation with high redundancy and protection against system failure. For controlling the heating circuit with the mixer and for one heating circuit without a mixer. Temperature regulation for one DHW storage and control of electrical auxiliary heating. Simple extension of control up to 3 heating / cooling circuits via expansion modules or up to 16 circuits via system controllers for RVS heating. The standard version also includes solar control, as well as the possibility of cascading up to 16 devices.

Full-text control menu with features dependent on user instructions, information texts and status output signal. Diagnostic system with record history of operation. External temperature sensor, hotplate sensor, coolant temperature sensor, heat pump heat pump temperature sensor and return temperature sensor as well as source temperature sensor at probe and evaporator inlet, hot water sensor.

Optionally available with ModBus module as well WebControl control and monitoring via the Internet.
