The economic and environmentally friendly option for the plumbing and heating engineer when servicing, repairing or extending pipe systems, without the need for time consuming draining down. Good for customer relations - no prolonged discussion about when to do the job, and no inconvenience is caused to third parties not involved by having to have their water turned off.

Ideal when replacing faulty parts, e.g. thermostatic regulator valves etc. Eliminates the risk of air-locks in heating systems. Only use CO2 cylinders with vertical feed pipes, ( liquid withdrawal ). Compact design of freezing heads allows for use in confined spaces, such as close to walls. Insulating seals wrap firmly around both sides of the pipe ensuring even, radial speedy freezing and controlled refrigerant feed. Finely adjustable needle valve on each handle. Bayonet connection with O-ring for a permanent, tight connection between feed valve and freezer head.
