36 AFTERMARKET MAY 2021 AIR CONDITIONING www.aftermarketonline.net W orkshops are dealing with a constantly growing demand for professional servicing of automotive air conditioning systems. Most of the vehicles produced throughout the last years are equipped with heating and climate control. For this purpose, the control unit ensures the functional interaction between actuators, A/C compressor, engine cooling fan and the cabin fan motor. It also controls the heating system and the flaps guiding the air flow into the cabin. In addition, several sensors supply the system with information concerning temperature zones inside the cabin, exterior temperatures, engine conditions and settings made by the driver. Accordingly, modern air conditioning service is much more than just standard routines. Using ESI[tronic] 2.0 Online and Bosch Connected Repair, Bosch A/C service units can be combined with troubleshooting and linked to diagnostic equipment to increase the efficiency of air condition servicing. Any workshop Featuring accurate measurement technology and fully automatic service routines, Bosch A/C service units efficiently service passenger car and commercial vehicle air conditioning systems. They are also suitable for electric and hybrid vehicles and meet the high demands of SAE J-2788, the technically demanding US standard applicable to A/C service units, and the European standards. The Bosch range includes suitable, powerful, fully automatic and user-friendly A/C service units to meet all According to Bosch, with the right kit, modern A/C service is more than just standard routines A COOL DREAM TEAM workshop requirements. Their step-by-step instructions guide the user through the A/C service. With these guidelines, even service tasks beyond the standard routines, such as A/C flushing or leakage detection, can be performed. The main reason for A/C flushing is the replacement of one of the system’s components – e.g. of the compressor. After all, flushing is compulsory for the manufacturer warranty to remain effective and to prevent damage to the new compressor from fragments and remnants within the refrigerant circuit. Bosch A/C service units stand out for their easy handling, fully automatic procedures and their particularly high performance. Thanks to their exclusive deep recovery system, both the premium and standard models recover up to 99% of the refrigerant even under difficult environmental conditions. The integrated forming-gas pressure test option allows accurate leak-proof tests. The ACS 563 and ACS 553 entry-level units support workshops with daily service tasks such as refrigerant recovery, filling and recycling. They feature a recovery rate of up to 95%. In addition, the top model ACS 863 automatically tests the purity of R-1234yf refrigerant. Moreover, ACS 763, ACS753 and ACS 863 also feature an integrated nitrogen and hydrogen pressure test. Using the WLAN dongle, the units can also be integrated into as a network or linked to Bosch Connected Repair workshop software. Modern diagnosis For comprehensive servicing of automotive air conditioning systems, the ACS units can be combined with ESI[tronic] 2.0 Online and KTS-series diagnostic solutions. This takes Bosch KTS 590 and 560
