This Onda S.p.A. S09 H-62 brazed plate heat exchanger is a 62-plate single-circuit unit for refrigeration and HVAC heat transfer. It uses 316L stainless steel plates copper-brazed for corrosion resistance and thermal efficiency, carries a 653 PSI design rating on both sides, and handles all common refrigerants except ammonia, including R410A, R404A, R134a, and R22. At roughly 13 in long by 3 in wide by 7 in deep (13 lb), it suits condensing units, heat pumps, chillers, and water-to-refrigerant applications around 4.8 tons. This unit shows light cosmetic wear consistent with prior handling or storage: surface tarnish on the plates and wear on the nameplate. It is fully intact and functional, sold as a sound used unit. Connections follow the standard Onda S09 single-circuit layout (config AA, four ports F1-F2-W1-W2): refrigerant inlet F1 at 5/8 in solder, refrigerant outlet F2 at 3/4 in solder, and secondary-fluid ports W1/W2 at 1/2 in gas thread. Confirm port type against the physical unit before brazing, as Onda builds special-connection variants. The unit is cULus Listed. OEM code X009062AA20001, serial R2117271-004, built 2021. King Surplus offers this as a high-confidence item backed by a 100 percent 14-day money-back guarantee less shipping. Surplus pricing well below new distributor list makes this an efficient replacement or spare for refrigeration technicians, OEM builders, and maintenance operations.
