The large face 7.94mm HVACR coil increases heat transfer efficiency. The copper tube coil, available in face sizes of up to 60 (60 tubes high) by 108 inches, offers smaller diameter tube and a more compact heat exchanger for enhanced performance in commercial applications, states the company. The design delivers high heat-transfer coefficient with improved performance in a longer length coil. It utilizes a compact tube pattern, delivering savings on raw material and refrigerant costs to commercial a/c and specialty HVACR equipment manufacturers, without sacrificing efficiency. The 7.94 mm design provides exceptional compatibility as a large evaporator being matched to the manufacturer’s aluminum microchannel condenser and outdoor heat pump applications where the coil operates both as condenser and evaporator in the reverse (heating) cycle, the company says.
