Luvata HTS North America has developed a new large face 7.94 mm HVACR coil to increase heat transfer efficiency and allow customers to address recent changes in refrigerant regulations and usage. 

The new coil surface is capable of capturing the benefits of the superior heat transfer properties of R-410A, the new refrigerant of choice being widely used by commercial air conditioning and specialty HVACR equipment manufacturers, the company said.

The large-face-engineered 7.94 mm copper tube coil, which is available in face sizes of up to 60” (60 tubes high) X 108”, offers a smaller diameter tube and a more compact heat exchanger for enhanced performance in commercial applications. Luvata’s new design delivers high heat-transfer coefficient with improved performance in a longer length coil.  

The large coil design uses a compact tube pattern, delivering savings on raw material and refrigerant costs to commercial air conditioning and specialty HVACR equipment manufacturers, without sacrificing efficiency, the company said.

Historically the coil of choice for commercial and large tonnage HVACR applications has been 3/8” or 1/2” tube heat exchangers up to 40” X 96” finned lengths, but new refrigerants have led to a need for new coil surfaces that can capture their benefits.  

Matching the characteristics of R-410A with a smaller diameter tube and more compact coil surface delivers a highly efficient coil product with improved performance.

In addition to refrigerant optimization, the expanded use of heat pump technology in the commercial HVACR market is driving manufacturers to search for new solutions. The new 7.94 mm design provides exceptional compatibility as a large evaporator being matched to Luvata’s Aluminum Microchannel condenser and outdoor heat pump applications where the coil operates both as condenser and evaporator in the reverse (heating) cycle.
