Notes

These heat pumps are bespoke to each and every installation so that we optimise the size of the heat exchangers for the flow and temperatures at both the evaporators and condensers. Using r600a or CO2, we’ll select the refrigerant based on the temperature profiles, for the lowest climate impact with GWPs of 3 and 1 respectively. Available up to 400KW in a single unit for r600a, larger for CO2, which keeps the hydrocarbon gas charge at a manageable level they can be multiplexed together for higher duties.
