The SI TER+ range uses a three phase electricity supply, making them suitable for a range of non-domestic/commercial applications with heat load demand.
The SI TER+ range provides the capability to be reversed to provide active cooling. Waste heat recovery in cooling mode allows extremely efficient hot water production.
Can be used to provide heating and/or cooling.
Waste heat recovery in cooling mode for swimming pool or sanitary water heating.
Variable heating water flow temperatures from 35°C to 60°C, weather compensator.
Variable cooling water flow temperatures form 20°C to 7°C.
Variable heating water flow temperatures up to 55°C
Twin compressors for higher capacity output and two performance capacities.
Intelligent load switching between compressors to maximise compressor life.
Suitable for use with under-floor heating, radiator systems and to provide domestic hot water.
Scroll compressor providing efficient, low noise running.
Three phase electrical connection with electronic soft start to reduce starting current loads.
Able to use ground water as a heat source with the addition of an intermediate heat exchanger.
