Denso Compressors are rotary types that operate as a pump to keep the refrigerant circulating and to increase the refrigerant’s pressure.

A/C Compressors

Auxiliary heaters available in 12V & 24V designed to deliver performance where it counts and are ideal in any application.

A/C & Heater Units

The Aeroquip EZ Clip system is an engineered hose and fittings solution for quick and easy connections, especially in confined areas without the use of powered tools.

Aeroquip EZ-Clip

Blower motors “blows” and circulates the warm air from the fins of the heater core or cools the air as it passes from the fins of the evaporator.

Clutch's engage and disengage the compressor from the vehicle's accessory drive system to enable cooling of the AC system.

Service Valves are used to allow refrigeration gauges to be attached to the system; and, if needed, they are used to isolate the compressor from the rest of the system.

Compressor Parts

Condenser are used to remove heat from an AC system. Mounted at the front of the engine, to use air flow from the forward movement and from the engine fan.

Condensers & Coolant Tubes

Evaporators are usually mounted inside the vehicle and has cool refrigerant flowing through it, which absorbs passenger compartment heat as the blower fan moves the warm air across it.

Expansion or TX Valves control the flow of refrigerant entering the evaporator, based on the cooling load or the evaporators temperature.

Expansion Valves

Filters help to remove particulate and allow the A/C system to run at optimal efficiency and passengers to breathe cleaner, fresher air.

Beadlock Fittings require hydraulic “crimping” to the hose and enable connectivity between the various components within the AC System.
