Available in 1/2 to 6HP configurations that are R-404A compatible, the new condensing units feature HyperCore microchannel coil technology to allow superior heat transfer capabilities and reduced refrigerant charges compared to standard copper-aluminum round tube plate fin (RTPF) coils.
The SLX uses R-404A as a refrigerant--a chlorine free chemical without depleting effects on the ozone layer.
Existing deep-freeze and blastfreeze systems using HCFC refrigerants like R-404A, R-22, or R-502, can be converted.
Part 2, published in the December issue, deals with selection of proper thermostatic charges, capacities of several refrigerant blends relative to both R-404A and R-22, and examines how existing components on the liquid side of a system may be affected by a retrofit to a newer, high-glide blend.
