Accu-Freeze™ and Qwik-Freezer™ Pipe Freezing Systems

HFT Pipestoppers® Pipe Freezing Systems are a solution to valve exchange in pipework and other pipe repair alterations.

Accu-Freeze™ uses liquid nitrogen (LN2) with jacket, copper coils or aluminium clam-shell style freeze jackets, available for pipe diameters from 2 – 12”.

The Qwik-Freezer™ System uses liquid carbon dioxide and a series of insulated freeze jackets to wrap around the pipes to freeze the contents inside the jacket. The system is quick and easy to use, requiring almost no set-up time.

It is the only CO2 pipe-freezing system capable of freezing up to an 8” pipe. Both Accu-Freeze™ and Qwik-Freezer™ Systems are extremely cost effective. The savings by not having to drain other liquid systems to make repairs are able to justify the low relative cost of these systems.
