testo 565i smart vacuum pump for automated evacuations with integrated vacuum hold test, 7 CFM / 198 l/min, 10 CFM / 283 l/mi The new testo 565i vacuum pump carries out evacuations on refrigeration systems and heat pumps fully automatically. When the desired vacuum target value is reached, pumping is automatically stopped and a vacuum holding test isstarted at the same time. Foreign gases and moistureare thus safely removed and data on the tightness of the system is stored. The data logging function ensures complete documentation. This means that evacuations can be carried out completely autonomously.
