GROUND SOURCE HEATPUMP DIMPLEX SI90TU WITH PUMPS
SI 90TU, 90 kW, designed for heating use with two compressors to enhance efficiency under partial load. Integrated heat pump control with WPM Econ5Plus standard display. Connections for brine and heating located at the rear of the unit. Sound-optimized metal casing with integrated sound insulation and freely suspended compressor base plate enable direct connection to the heating system. Service access from the front; no minimum side clearance required, can be lifted with a forklift. High performance coefficient due to electronic expansion valve, COP booster, and electronic pump control, depending on temperature spread in the heat collection brine and generator circuit. Refrigerant circuit sensor monitoring for high operational safety and integrated heat energy measurement (display showing calculated heat energy for heating, domestic hot water, and swimming pool water production). FWO function for more efficient domestic hot water production, elevated domestic hot water temperatures and optimized water volumes achieved through optimized tank charging.
Universal design with two compressors for power modulation under partial load, optional domestic hot water production, and flexible expansion options: bivalent or bivalent renewable operating mode. Heating/cooling systems with unmixed and mixed circuits. Use of variable tariffs (SG Ready). Soft starters, flow and return sensors for heat collection and integrated heating circuit. Dirt separator for heat collection circuit, external sensor (standard NTC-2), circulation pumps for heat collection and heat generation circuit included in delivery (note free compression). Brine circulation pump; 12 m head, 11 m³/h, flange connection DN 65, installation length 340 mm. Heating charge pump; 8 m head, 14 m³/h, flange connection DN 65, installation length 340 mm.
