We are committed to always delivering quality. And that’s exactly what you can expect from our extensive air conditioning portfolio. Many of our products in this range are available in two variants: OE, known as the MAHLE Premium Line and OE-matching quality.
The A/C condenser is the counterpart to the A/C compressor: The latter compresses and heats the refrigerant, while the condenser reduces the temperature again. To this end, the gas flows through the pipework and fins of the A/C condenser installed upstream of the coolant cooler, thereby emitting heat. This lowers the pressure and causes the refrigerant to liquefy.
Interior blower
Providing a clear view and pleasant climate inside the vehicle, interior blowers from MAHLE not only play a significant role in terms of comfort, but also for the safety of drivers and front-seat passengers.
Evaporator
The evaporator is a core element of temperature management. It is located in the vehicle cabin below the dashboard and is integrated into the ventilation system. The evaporator takes care of the heat transfer between the surrounding air and the refrigerant in the air conditioning. MAHLE evaporators are characterized by their high performance, small packaging depth, and low weight.
A/C blower control unit and resistor
Blower control units regulate the blower fan and thus the air flow in the passenger cabin. MAHLE offers a number of different control unit variants that work either electrically or electronically. The electric blower control units have several resistors and, in most cases, an integrated thermal fuse—in case of overload, they’re switched off to protect other components. The electric control units allow the fan to be operated at different speeds.
A/C compressor oils
The quality of the A/C compressor oils used is crucial for ensuring that the air conditioning can be used safely and for a long time. The use of low-grade or incorrect oil results in increased wear and may lead to premature failure of the A/C compressor. MAHLE offers a range of synthetic compressor oils.
Filter-drier and accumulator
The carefully produced MAHLE filter-driers, which—depending on the system—are also called accumulators, prevent this: the liquid refrigerant flows through this component and passes through a hygroscopic filter, which retains both moisture and fine particles.
Expansion valve and orifice tube
The expansion valve or the orifice tube is located upstream of the evaporator and separates the high- and low-pressure areas in the refrigerant circuit. The liquid refrigerant is injected into the evaporator via the valve, where it is converted into gas, producing the required evaporation cooling.
A/C switch
MAHLE A/C switches reliably control various shunt relays and are responsible for switching individual systems components on and off at specified pressure points. This means that the air conditioning can be used safely and effectively at all times and in any conditions.
Electric control for blending flap
Electrically driven controls for MAHLE air conditioning systems fulfill even the most stringent demands: they’re primarily used in automatically controlled air conditioning systems to control air flaps or mixing flaps. In this way, they ensure optimal distribution of the air flow within the vehicle cabin.
