Key Features: 1. Compact size, high strength, lightweight, and easy to carry. The volume is only 139.5 liters, suitable for carrying in a three-box car. Fast recycling, easy operation, especially suitable for rapid recovery, refueling, and purification for screw-type centrifugal chillers. Compatible with various refrigerants. 2. Open-type compressor designed for recycling operations. The motor is separated from the compressor to ensure no contamination of the refrigerant recovery. 3. Water-cooled design available with an optional external independent air-cooling system. High cooling efficiency, easily achieving liquid storage. 4. Equipped with a large D48 filter and an efficient oil separator to ensure no secondary contamination during refrigerant recovery. 5. Four-way valve design allows for different recycling methods without changing pipeline connections. Push-pull recovery, quick switching between conventional recovery. 6. Comprehensive protection system ensures safety and reliability with phase protection, current protection, high-pressure protection, and low-pressure protection. 7. Complete recovery of refrigerant with an ultimate suction pressure reaching -0.04 Mpa, automatically shutting off the machine upon completion.
