The 17800B recovers, recycles, evacuates and recharges -- all in one fast, continuous operation through one hook-up. It's ideal for refrigerated trailers, buses, RV's, and other vehicles that use more than one refrigerant. The Cool-Tech Multi is also great for fleet maintenance, covering, a variety of makes and models since it has R-12 and R-134a capabilities. In-plant maintenance departments will find it can handle the different types of refrigerants used in various systems. Recovers, Recycles, Evacuates and Recharges R-12, R-134a R-22, R-502 M and HP Blends - and many more! Proven Technology simplifies service! Microprocessor: Controls functions; prompts lead you through programming and also signal when it's time to change the filter-drier, vacuum pump oil and compressor oil. Float Chamber: Automatically adjusts from liquid to vapor for most efficient recovery. Electronic Scale: Makes it simple to recharge to factory specifications; also weighs recovered refrigerant and provides tank overfill protection. Cool-Tech Vacuum Pump: 6 CFM has the capacity to thoroughly evacuate system, readying it for recharging. Versatility for many types of systems! Lockout Panel: Prevents mixing of refrigerants; slides to one side for 1/4" fitings and to the other for 1/2" Acme fittings. Single Pass Recycling: Makes an initial pass through the filter-drier; additional recycling can be programmed in case of compressor burn-out, other conditions. Heavy Duty Filter-Drier: Removes moisture and acid from the refrigerant; can handle up to 300 pounds between changeovers. Comes with two 50 pound tanks, one with 1/4" fittings and the other with 1/2" Acme fitings. Also three sets of charging hoses are included - one for R-12, one for automotive R-134a (with field service couplers), and one for other refrigerants using 1/4" SAE fittings.
