Commercial Heatpumps How it works This series serves centralised hot water systems where a large storage tank feeds multiple outlets. Cold water enters from the hydropneumatic system, the heat pump raises it to the set temperature through a tube-in-shell or brazed plate condenser, and a circulation pump maintains a ring main so hot water is instantly available at every tap. Return water from the rooms re-enters the loop, minimising both wait time and wastage. Construction and features Scroll compressors, tube-in-shell heat exchangers, blue-finned evaporator coils with hydrophilic epoxy coating that sheds condensate and resists corrosion. Electronic expansion valve, smart-touch control, HP/LP safety protection, anti-corrosive cabinet coating and optional automatic defrosting. Stable, low-vibration running with two or four compressors per unit for staged capacity. Specifications SE-AH-14U through SE-AH-180V, covering 14 to 180 KW heating capacity.
