Evaporator optimised for R407C in small high-eciency residential ground source heat pumps with capacities between 2-8 kW. The heat
exchanger features innovative Micro Plate technology that improves heat transfer and reduces the amount of material used.
To meet demands for higher COPs in heat pumps, the H22-E is designed to work eciently with close temperature approaches, while a low
pressure drop on the brine side reduces the pump power and keeps the overall COP high.
The low hold-up volume reduces the refrigerant charge and oers valuable savings.
• Minimal hold-up volume: Less refrigerant charge
• Reduced pressure drop: For a more ecient heat pump
• Smaller footprint: Enabling more compact heat pumps
• Reduced CO2 footprint: Environmentally friendly with high heat transfer and minimal refrigerant charge.
