Pure energy extracted from the ground water
Extremely efficient
The energy performance of the water-to-water heat pump models sets standards. The ratio of the free environmental energy gained and the electric energy input is extremely favorable
Sunte offers the new generation of water-to-water heat pumps. The compact Sunte heat pumps ensure powerful and comfortable heating in a minimum of floor space. Heating capacities of up to 27 kw can be produced using ground water of nearly all quality levels. This means that the sturdiness of the Sunte devices sets new standards. An innovative spiral-type heat exchanger made of corrosion-resistant stainless steel, with even its solder seams sealed, ensures permanent operational reliability
Innovative freeze protection
Sunte stands for maximum operational safety. The spiral heat exchanger is protected against local ice formation on the inside due to its special geometry
Silent cooling
Brine-to-water heat pumps
Space-saving design with a footprint of 500 x 600 mm
Insulated flexible connecting tubes for connection to the heating and brine circuits
Integrated heat pump manager with 4 x 20-character LCD screen, comfortable 6-button operation, menu-guidance in plain text as well as diagnostic function
Vibration isolation of entire refrigeration circuit
Integrated soft starter for limiting the starting current to 30A
Top performance figures
The economizer installed as standard optimizes the refrigeration circuit and improves the coefficient of performance
