CROSSCOOL™-enhanced coils feature tubes with an embossed internal surface, rather than the traditional smooth-bore tube design. This ridged surface adds more surface area within the coil, which in turn increases the turbulence of the fluid passing through it, and raises the internal heat-transfer coefficient. With CROSSCOOL™-enhanced coils, all EVAPCO closed-circuit coolers now have an average four percent increase in thermal capacity over previous smooth-tube, closed-circuit coolers of the same footprint and fan motor horsepower.
EVAPCO first introduced CROSSCOOL™ in 2013 as a feature of its highly energy efficient ESWB line of closed-circuit coolers. With this most recent expansion, CROSSCOOL™ is now available in all 11 of EVAPCO’s closed-circuit cooler product lines, which include the ATWB, cATWB, eco-ATWB, eco-ATWB-E, eco-ATWB-H, ESWA, ESWB, LRWB, LSWE, eco-LRWB and eco-LSWE.
