It doesn't just extract the refrigerant—it's the gatekeeper that "locks" the escaped greenhouse gases back into the steel cylinder. With a 0.1-second rapid start-up, negative pressure reaches -0.09 MPa, and the recovery speed increases by 40%, yet it only consumes 800 W—less power than a household hair dryer. The 316 stainless steel double cylinder is corrosion-resistant, resistant to liquid impact, and does not become brittle at -30°C or soften at 60°C. The pump body does not need replacing for 10 years. The intelligent level sensor automatically stops when the steel cylinder is 90% full and provides audible and visual alerts at 80%, preventing "overcharging explosions" and avoiding "undercharging waste". One-click self-cleaning sends residual oil, residue, and acid value back to the waste tank in 30 seconds. When switching to a different refrigerant tomorrow, there's no cross-contamination or quality degradation. The entire machine weighs 18 kg, lighter than a bucket of water. With side handles and bottom rollers, it can be carried up stairs with one hand, even more obedient than a toolbox. R32, R410A, R290, R744... Whether new or old, flammable or non-flammable, it includes a built-in database of 70 refrigerants, automatically matching pressure curves and locking the screen in case of misoperation. Before leaving work, extract the last 5 g of refrigerant, and the work order is automatically uploaded to the cloud. Customers can sign off on their phones, and the EPA data is synchronized—this is the true "closed loop". A refrigerant recovery machine isn't just a cost—it's a "printing press" in the carbon tax era. Today, let every gram of refrigerant "go home", and tomorrow, let the Earth emit 0.01 less CO2.
