Featuring additional functions and increased performance, the new Robinair AC1x34-7i, AC1234-7i and AC1234-8i A/C service units have been designed for efficient maintenance and repair tasks on passenger-car and commercial-vehicle air conditioning systems working with R134a and R1234yf refrigerants.

The new units include all functions for maintenance and repair tasks with the ability to optimize and ease workflows at service centres thus increasing their economy. Designed to operate automatically, the new A/C units feature a graphic user interface with a 7-inch colour display supports the workshop employee concerning both operation and monitoring.

In addition, the display also provides instructions on service preparation tasks and maintenance procedures. Via smartphone app, the user can also check the device status and the work progress in real time and remotely (such as from another work station). As the new design based on user experiences eases the access to the interior components, the maintenance of the new A/C service units is very simple too. The new devices meet all OEM international standards for a more environmentally friendly handling of both of the refrigerants.

In addition to providing greater ease of use, the Robinair series of A/C service units AC1x34-7i, AC1234-7i and AC1234-8i feature improved performance compared with their predecessors. Releasing non-condensed gases is now controlled electronically reducing the risk of refrigerant loss. The new devices recover 99 percent of the refrigerant from the vehicle in shorter time thanks to exclusive “Deep recovery” function. Electronic pressure and temperature controls ensure a premium level of precision at the refrigerant filling.

A two-stage vacuum pump with a flow rate of 170 litres per minute allows quick and efficient maintenance assuring dehydration before re-charging – even for rather big air conditioning systems used in light commercial vehicles (LCVs) and trucks. An independent and hermetically sealed fresh-oil injection system prevents cross contamination of different oils. The new A/C service units are perfectly suitable for both vehicles with combustion engines and those ones powered by electric drives. The top line Robinair AC1234-8i also checks the degree of purity of the R1234yf refrigerant.

The new Robinair AC1x34-7i, AC1234-7i and AC1234-8i A/C service units are equipped with a vehicle database and software, which can be connected with Bosch’s Connected Workshop or the ASA network respectively. This allows quick exchange of data between A/C service units and workshop software. The integrated printer also enables a transparent overview of maintenance results for both operators and workshop customers.
