Whether you are replacing a burnt-out unit on a supermarket roof or speccing a new cold storage plant, the K373HB offers a sweet spot: enough capacity for 15-20 kW of cooling, with the ability to repair it in situ. Just remember the golden rules:
The was originally optimized for R22 (now phased out globally) and R404A / R507 . However, with the global shift toward lower GWP refrigerants, modern applications often use this compressor with R448A (N40), R449A , or R134a (at higher temperatures).
A new Bitzer K373HB compressor (bare unit, no oil, no controls) retails between $2,500 and $3,800 USD depending on the region and voltage. A factory remanufactured unit is typically 40% less.
and maritime environments. It features a robust, corrosion-resistant design using copper-nickel tubes, making it a standard choice for marine refrigeration and cooling. Core Specifications
This unit is typically used for . It is not a small duty compressor; this is a heavy lifter for walk-in freezers, refrigerated display cases, and industrial chillers.
When ordering or replacing a K373HB, confirm:
The is a high-performance shell-and-tube water-cooled condenser specifically engineered for demanding seawater applications . As part of Bitzer’s K..B series, it is a staple in marine refrigeration and offshore cooling systems where corrosion resistance and thermal efficiency are critical. Key Technical Specifications
: High-grade copper-nickel 90/10 (CuNi10Fe1Mn) , which provides excellent resistance to seawater corrosion.
The longevity of the K373HB in the market is not an accident; it is the result of specific engineering choices that prioritize reliability.
