The RIDGID SF-2500 (68967) SuperFreeze Pipe Freezing Unit for Steel Pipe and Copper Tube, 115V, is an easy-to-use pipe-freezing unit that allows a contractor to keep water systems operating while making repairs. The Model SF-2500 is a mini-refrigeration unit that circulates self-contained refrigerant to its aluminum freeze heads. This forms an ice plug in as little as 6 minutes. The freeze heads, attached to the piping system, can freeze a plug in copper tubing or steel pipes. Once the pipe is plugged, repairs can be made while the ice plug is maintained by the unit. Once the work is complete, the SuperFreeze unit is turned OFF and the ice plugs melt, returning the system to operation.

The SuperFreeze unit does not use CO2 or Nitrogen, and does not require the release of refrigerants. It uses a specially designed compressor with overload protection. The SF-2500 also includes quick restart capabilities. The freeze head hoses are leak-free flexible rubber. The unit is enclosed in a portable carry case.
