The patent-pending SHC onDEMAND modular heat pump system eliminates the need for separate heating and cooling equipment by combining them into one compact unit, saving installation costs, reducing physical footprint, and lowering overall operating costs, says the company. It is available in modules from 30 to 85 tons, with bank capacity to 1,000 tons. The modules offer cooling efficiencies up to 25 EER and heating efficiencies up to 5 COP. The six-header design can be utilized with cooling towers, geothermal (ground and lake) loops, or hybrid systems for true application flexibility. The unit allows any module to be indexed for heating or cooling regardless of its position in the bank to provide optimum performance and compressor run time equalization. Mechanical room space is maximized through innovative connection flexibility for hot, cold, and source loops, and the piping is fully configurable to same or opposite ends.
