Comprehensive Range: HELLA provides a wide selection of compressors suitable for various vehicle makes and models, catering to a broad spectrum of customer needs.

How does it work?

The A/C compressor in a vehicle is a crucial component of the air conditioning system. Its primary function is to compress and circulate refrigerant throughout the system to cool the cabin. Here’s how it works:

1. Compression of Refrigerant: The compressor pressurizes the refrigerant gas, increasing its temperature and pressure. This prepares the refrigerant for the heat exchange process.

2. Circulation: The compressor pushes the pressurized refrigerant into the condenser, where it releases heat and changes into a high-pressure liquid.

3. Refrigeration Cycle: The refrigerant then flows through the expansion valve or orifice tube, where it expands and cools significantly. It moves into the evaporator inside the vehicle, absorbing heat from the cabin air and cooling it.

4. Repeat Cycle: After passing through the evaporator, the refrigerant returns to the compressor as a low-pressure gas to start the cycle again.

The A/C compressor is driven by the engine via a belt and pulley system. It typically has a clutch that engages and disengages the compressor to regulate cooling as needed. Proper function of the compressor is essential for maintaining comfortable cabin temperatures and ensuring the air conditioning system operates efficiently.

Why and when to replace?

Loss of performance: If the compressor struggles to maintain the desired pressure or becomes less efficient.

High energy consumption: An inefficient compressor can consume more energy, leading to higher operating costs.

Wear or corrosion: If critical components like pistons or rotors are damaged due to wear or corrosion.

Frequent failures or repairs: If the compressor needs regular repairs, the costs may exceed the value of a new unit.

Technological advancements: Newer models often offer better efficiency and lower operating costs.

Replacement makes sense when repair costs rise or the compressor loses performance.
