The Yellow Jacket® charging scales are designed to work with any refrigerant in any system. It eliminates the time and cost of charging cylinders and eliminates refrigerant transfer from tank to cylinder to systems; therefore, there’s no concern about residual refrigerant in a charging cylinder, states the manufacturer. Weigh the refrigerant container and charge directly into the system or recover from the system. The scale is available in a new, heavy-duty, 220-pound capacity model or a 110-pound model.
