Optimized Energy Performance Exceeds ASHRAE 90.1 minimum efficiency requirements.
Thermal Comfort Precise required heating and cooling ensures the highest comfort for building occupants.
Simultaneous Heating and Cooling Heat Pump SHC onDemand modular chiller helps reduce energy consumption and the environmental impact of heating and cooling equipment by harnessing energy that is already being produced but not used. The simultaneous modular system eliminates the need to have separate equipment for heating and cooling while saving installation cost, overall operating cost and reducing the physical footprint. The SHC onDemand allows dramatic energy savings to be achieved, by more than 50%, when compared to conventional systems.
onDemand Operation Allows any module to be indexed for heating or cooling regardless of its position in the bank, providing optimum module/compressor run time equalization. Integral motorized isolation valves and dual independent refrigeration circuits per module provide true mechanical redundancy.
Simplicity Patent pending, four (4) header design simplifies installation, design and controls. Simultaneously, the SHC satisfies required heating and cooling demands without the use of inter-module/ external header isolation valves, controls, associated logic, piping or wiring. Innovative engineering simplifies the simultaneous heating and cooling process, taking multitasking to a whole new level.
Ultimate Efficiency The CoolLogic Control System provides advanced algorithms for maintaining precise leaving chilled and hot water temperatures. Integral motorized valves allow for variable pumping on heating and cooling water loops. High efficiency design offers a minimum of 10 EER cooling efficiencies with typical heating efficiencies around 3.0 COP
