The WAECO ASC 3500 G offers all the benefits of our Low Emission technology: almost 100 % refrigerant recovery and virtually no harmful emissions into the atmosphere. Plus, an exact identification of the recovered amount of refrigerant avoids unnecessary troubleshooting and repairs. Integrating a powerful vacuum pump, the ASC 3500 G qualifies for highly efficient A/C service on large vehicles, such as buses, trains and helicopters. An additional fluid pump ensures fast refrigerant recharging. Charging will be even faster if you add the optional heat belt, which saves up to 80 % work time .
