Cross-Referencing Danfoss Refrigeration Components by IMPA and OEM Code

Cross-references Danfoss refrigeration components (expansion valves, solenoid valves, pressure switches, filter driers) to their IMPA marine catalog codes and typical OEM alternatives. Covers TU / TE / TGE thermostatic expansion valves, EVR solenoid valves, KP / RT pressure switches, and DML / DCL filter driers. Includes selection rules for R404A, R410A, R448A, R449A and CO2 (R744) refrigerants.

Product families covered

Danfoss ships refrigeration components under distinct code families. Each family covers one function; within a family the code encodes the size and, where relevant, the refrigerant compatibility. The families listed below all appear regularly on IMPA marine stores requisitions and on shore-side commercial refrigeration BOMs.

Thermostatic expansion valves (TXV)

Solenoid valves

Pressure switches and pressure controls

Filter driers

IMPA cross-reference notes

The IMPA Marine Stores Guide indexes Danfoss thermostatic and solenoid valves under section 79 (refrigeration). The listed IMPA code resolves to the Danfoss code number rather than the OEM part number, so buyers should verify the Danfoss code number against the Danfoss product store before issuing a purchase order. Where the vessel operator holds a class-society-approved BWMS or refrigeration plant, the Danfoss component's class-society type-approval certificate must accompany the delivery.
