DualPAC

Two-stage ammonia-based heat pumps

Two-stage ammonia-based heat pumps with capacities of up to 2500 kW


SABROE DualPAC heat pumps combine ChillPAC, HeatPAC and HeatPAC HPX units into one single heat pump, using an ingenious modular system that makes it possible to achieve high temperature lifts, with the advantages of compact design and attractive operating economics.

The DualPAC is a two-stage high-temperature heat pump configuration that uses ammonia as refrigerant, and is designed with the sole aim of best possible performance and versatile operating conditions along with the same practical benefits – including small refrigerant charges and limited footprint – as any other SABROE heat pump. This unique setup ensures maximum flexibility in both configuration and capabilities, because all standard ChillPAC and HeatPAC models can be used.
