Hoffman VA082025G052S Enclosure Cooling Air Conditioner Unit

Module Feature

VA082025G052S is a high cooling capacity enclosure air conditioner from Hoffman V series.

It provides 2000W cooling output for high heat-load electrical cabinets with drives, PLC and power modules. It adopts passive condensate handling design without drain piping. Galvanized steel sealed housing meets IP56 ingress protection, suitable for dusty workshop environments. It can be installed by surface mount or semi-recessed mounting. Widely stocked as spare for water treatment, extrusion, machine tool and heavy industry control cabinet thermal management.

Working principle

Refrigeration cycle consists of compressor, condenser, expansion valve and evaporator.

Internal cabinet air flows over cold evaporator coil to remove heat, and heat is discharged to ambient air via external condenser. Built-in thermostat maintains stable cabinet temperature. It continuously monitors coil temperature and compressor status, triggers alarm or compressor protection when overheat or fault occurs.

Onboard components

Hermetic compressor, evaporator coil, condenser coil, expansion valve, mechanical thermostat, internal and external cooling fans, R134a refrigerant circuit, sealing gasket and galvanized steel housing.

LED indicators

Front LEDs indicate power supply, cooling running and fault alarm status.

Hardware self‑diagnosis

Unit monitors internal cabinet temperature, condenser temperature and compressor operation. Temperature setpoint can be adjusted on local thermostat panel.

Programming software

Not applicable, local panel adjustment only.
