AC servicing in the spotlight with Bosch
Bosch’s workshop equipment portfolio includes a complete range of air conditioning (AC) service units.
“AC service units for buses and trucks must be designed to cope with high system volumes, special components and functions of large air conditioning systems,” said Bosch.
“Bosch ACS 810 AC service units are designed for specifically these demands and R134a-based AC systems with high capacities, featuring workshop-friendly hardware and a user-friendly menu navigation. There are also components optimised for bus systems and a complementary range of accessories.”
The ACS 810 automatically manages recovery, recycling and refilling of refrigerant. Their 5-metre service hoses can be connected to all R134a AC systems. Integrated 2-litre oil bottles receive large amounts of compressor lubricant during the oil injection and recovery.
A double fan ensures temperature control and constant refrigerant pressure during the recovery phase. This protects the internal components against overheating. By means of the 0.5 bhp high-performance pump, the system is quickly filled with refrigerant. The integrated tank will hold up to 35 kg of refrigerant.
Two operation modes are available for the AC service: fully automatic or manual recovery, vacuum and filling functions. A continuously updated database includes the values for practically all European cars, vans, LCVs and trucks.
If blockages, clogging or receiver-drier defects are identified, or if components need to be replaced, dirt particles must first be removed by thoroughly flushing the system, says Bosch. For this purpose, an optional flushing kit can be ordered for ACS 810.
The company concluded: “By means of ACS 863 (for R1234yf refrigerant), ACS 753 (for R134a) and complementary accessories, Bosch provides modern AC service units. ACS 863 automatically detects the refrigerant used. The deep-recovery function of both of these devices means that the vehicle AC system can be almost completely drained, due to the recovery rate of up to 99 per cent.”
