Highly efficient heating and cooling.
The SI 50TUR is a highly efficient brine-to-water heat pump for heating and cooling.
The cooling can take place actively via the refrigeration circuit and passively via an external heat exchanger. The control is so intelligent that it uses the natural cooling for as long as possible, cooling directly via the cold brine of the geothermal probe. The system only switches automatically to active cooling operation in case of high cooling requirements or if the temperature of the probes is too high. The cooled heating water can also be used for cooled ceilings based on the dew point (silent cooling) via the integrated control for dynamic cooling. Cooling is also already used as standard in offices and commercial buildings, as cool heads work more efficiently. A reversible heat pump can fulfil both requirements easily with minimal additional costs: Heating and cooling.
