No complicated hookups! Ideal for preventive maintenance programs and for multiple, medium to large AC&R units.

For all AC&R systems, including high-pressure R-410A systems! Compatible with Mineral Oil, PVE, Polyol Ester and Alkyl Benzene Lubricant Systems.

  • Cost effective for medium to large size systems — Each prefilled, disposable 4 oz (118 ml) BigEZ dye cartridge treats up to 16 gallons (60.8 L) of lubricant, 400 lbs (180 kg) of refrigerant or 150 tons of cooling.
  • No pouring, no refrigerant, no spills — Prefilled Big-EZ™ cartridges are clearly labeled with 32 calibrations so you’ll introduceexactly the right amount of dye every time! When the cartridge is empty, just throw it away. A new one connects in seconds.
  • Check valve prevents the backflow of dye or refrigerant and allows for easy storage of the hose/cartridge between jobs. It also prevents dye leakage or contamination. Torque
    from the Big-EZ™ assembly easily overcomes AC&R system pressure, even with R-410A.

Most economical for larger systems. Works in all systems, including high-pressure R-410A systems!
