Qwik-Freeze Pipe Freeze Kits

Qwik-Freeze Pipe Freeze Kits temporarily isolates the water in the system and allows repairs or modification to be made without draining or shutting off systems.

Qwik-Freeze Pipe Freeze Kits – Easy to use

The Qwik-Freezer™ kit is easy to use. A specially designed jacket is wrapped around the pipe at the point where the freeze is required. A nozzle on the jacket is then coupled to a cylinder of liquid CO2 by means of a high-pressure hose. 

When liquid CO2 is injected into the space between the jacket and the pipe, it immediately expands to form a solid carbon dioxide (dry ice) at a temperature of -70ºC (-108ºF). This low temperature quickly freezes the water inside the pipe, forming a secure ice plug, which seals in the pipe.

The ice plug forms only in the section of the pipe covered by the jacket so the resulting rise in pressure is very small and there is no damage to the pipe. The technique can be used safely on iron, lead, stainless steel, copper, brass and plastic pipes. 

Qwik-Freeze Pipe Freeze Kits – Major advantages:

• Saves valuable time normally lost draining and refilling a system.
• Avoids complete shutdown of systems and equipment (as in a sprinkler or water supply system).
• Prevents large amounts of water wastage.
• Safe and cost effective.
• Standard products to suit pipe and tubes sizes from 3/8″ to 8″ (10 to 200 mm ø).
• Liquid CO2 is inexpensive. 
• Other refrigeration systems are more expensive.
• Long freeze length provides large plug size.
• Liquid CO2 delivery system is notably colder than other refrigerants.
• Qwik-Freezer™ Systems allow operators to source their own CO2 (no expensive refills, replacements or refrigerants). 
• No re-calibration of Qwik-Freezer™ products are necessary. 

Pipestoppers® Qwik-Freezer™ is designed and manufactured to suit pipe and tubes sizes from 3/8″ to 8″ (10 mm – 200 mm ø).

Portable Pipe Freezing Kit with Qwik-Freezer™ : Application ‘replacing a defective valve’: 

• The water in the pipe is brought to a static condition.
• The Qwik-Freezer™ jacket is wrapped around the pipe (placed at a nearby upstream location).
• The liquid CO 2 is injected into the jacket.
• The CO2 rapidly freezes the water inside the pipe, permitting valve removal for servicing the replacement.
• An optional second jacket is available when a double freeze is required to block flow on both sides of the valve.
