SWEP’s new 250AS model is specifically developed for high-efficiency air- or water-cooled reversible chiller applications. Large ports and asymmetric plate design enable an effective operating range of 80-250 kW (23-71 tons). The company says AsyMatrix® plate pattern specially designed by SWEP improves heat transfer while decreasing water pressure drop and refrigerant charge. The new 250AS model is optimized for high performance with the refrigerants R410A and R32. The new 250AS model joins SWEP’s range of AHRI-certified brazed plate heat exchangers (BPHEs).
