Emerson says the new RIDGID SF-2500 SuperFreeze pipe-freezing unit quickly and easily isolates sections of copper or steel pipe with ice plugs, eliminating complete system shutdowns and draining. The RIDGID SF-2500 forms ice plugs in as little as five minutes in steel pipes up to two inches and copper tubing up to 2 1/2 inches, says the company. One or two plugs can be formed with a single unit at the same time. The RIDGID SF-2500 unit operates automatically once the freeze heads are attached to the pipes and the unit is turned on. The unit continues to run during repairs, ensuring the ice plugs don’t melt. Flexible rubber hoses connecting the freeze heads to the unit make them easier to handle and allow for quicker coiling and storage in its rugged stainless steel carrying case, says the company.
