Mahle says its aftermarket A/C service units have an automatic leakage test function as well as connector couplings, which completely eliminate the risk of escaping refrigerant.

Refrigerant analysis units from Mahle Aftermarket also recognise all common types of refrigerants, making it possible to recycle them by type.

The E3 technology in Mahle A/C service units is based on three components. With the patented E3 fill process, the air conditioning system can be filled regardless of vehicle and ambient temperature.

With the E3 pump, the internal cleansing process for the vacuum pump, oil change intervals can be extended to up to 1,000 operating hours; a tenfold increase. Mahle maintains this means the annual oil change no longer applies, with the benefit of shorter service times and lower costs.

With the third component, the patented E³ connect couplings, the refrigerant can be fully recovered from hoses and service fittings.

“Mahle’s A/C service units are now helping to make A/C service at workshops more safe, economical and eco-friendly,” said Mahle Aftermarket corporate EVP and GM, Olaf Henning.

With its latest generation of A/C service units, Mahle Aftermarket is also expanding its range for workshop connectivity: Using a smartphone app, workshop technicians can view the workflows and unit status and automatically order a service when needed.

The ASA interface on the unit and the integration of the unit in the workshop network ensure fast data exchange. The large touch screen, which is standard on all units, provides a continuous display of all information and programmed procedures, as well as the current status.

A start can be initiated at any time. The service technician can continue to work on the vehicle while automatic software updates are performed in the background via Wi-Fi.

Possible leaks in the air conditioning system are detected with nitrogen or forming gas via a direct connection to the air conditioner.

For a time-saving service, the devices can be serviced remotely via Wi-Fi: workshops can thus obtain fast support directly on the unit.
