It's not just about "extracting gas", but also turning the scattered refrigerants back into assets. - Three-stage compression without oil lubrication, with a 40% increase in recovery speed, compatible with R32, R410A, and CO₂. - An electronic scale with 10 g precision measurement allows real-time monitoring of recovery quantities, eliminating clients' concerns about "short weight". - An electromagnetic valve automatically switches between liquid/gaseous states, eliminating the need for constant supervision, allowing one person to monitor three systems simultaneously. - Explosion-proof enclosures ensure stable operation even in -20°C cold storage environments, earning praise from engineering teams in both northern and southern regions as "extremely durable". - Turn leakage fines into recovery profits, saving enough money to purchase a new machine in a year. - Refrigerant recovery machines - making environmental protection a profit center, not a cost center.
