Save valuable time when servicing the air conditioning on vehicles with large refrigerant volumes, such as buses and trains. Since downtime is extremely costly for operators, key service tasks such as refrigerant recovery, evacuation and refrigerant recharging need to be performed within a tight timeframe. The WAECO ASC 6400 G perfectly meets these requirements. Featuring a 192 l vacuum pump and an extra fluid pump, the fully automatic service unit guarantees fast and efficient refrigerant recharging. It can be upgraded with a heat belt to save a further 80 % work time. The ASC 6400 G optionally features the fresh oil and UV additive feeding system. It allows moisture-free and clean storage of refrigerant oils even over longer periods of time and therefore cuts A/C service costs.
