General Usage
|
How do you know when enough product has been used and the pipe has frozen?
|
You will hear a click when the ice plug has formed and reached the pipe wall. The release of refrigerant should be continued for 30 seconds after this click to ensure the plug has formed along the length of the pipe. There will also be visible frost on the jacket.
|
How many freezes can you get from a can of ZE1/ZE2?
|
It depends on the conditions in the room and size of the pipe. However, normally ZE1 can complete 1 x 8-15mm freezes and ZE2 can complete 2 x 8-15mm freezes or 1 x 28mm freeze. For any more information please see the freezing guide on the can.
|
Will the pipe freezing cans work if the can is tilted?
|
Yes, the cans will work if tilted but will not work if the can is upside down.
|
Will the pipe freezing kits freeze a 15mm hot water pipe? The water cannot be stopped and the temperature is 40 degrees.
|
No, all running water needs to be stopped. Turn water off at the mains or ensure there is no running water in the building. The pipe will not freeze if there is any running water. It will freeze hot water, but this will take more time than freezing cold water.
|
Can a soldered joint be affected by freezing the pipe?
|
Freezing a soldered joint wouldn’t have any affect unless the joint has pre-existing damage.
|
The stop tap / valve isn’t 50cm away from the jacket, will this affect the freezing process?
|
Ideally the jacket needs to be at least 50cm (18”) away from a valve / stop tap. If this is not possible the valve needs to be open so the pressure can escape. If the valve is closed / cannot be opened this can cause the pipe to split.
|
Can pipes be frozen if there is anti-freeze in the system?
|
Yes, the pipe can be frozen but it will take more product and time to freeze.
|
What temperature do the disposable kits go down to?
|
The flash off temperature is approximately -50°C but the stabilised temperature is around -30°C.
|
Do the freezing jackets have a limited number of uses?
|
The AERO jacket (ASM01) is disposable and designed for single use only. The PRO jackets (MUFF) have no limited number of uses.
|
Can you freeze a pipe if it is attached to a wall?
|
Yes, as long as the jacket can be placed around the whole of the pipe the freeze will work.
|
The can leaks when I use it / I don’t get the same number of uses from the can as you advise. What am I doing wrong?
|
Attach valve to the top of the can and fit the nylon tubes, Open the valve on the can allowing the refrigerant to enter the jackets. To release the refrigerant, slowly turn the value ….if you flood the jacket(s), refrigerant will start leaking out of the ends of the jacket, reduce the supply by turning the value back until you have no leaking/dripping, continue until you have used the dose indicated on the can or you hear the “click” sound, this indicates the ice plug has formed. Aim for the jacket to starting to go white with frost (after a short time) with no leaking. Once the ice plug has formed, wait a further 60 seconds before you start your repair.

Product Details
|
Can ZE1 & ZE2 freeze steel, plastic & iron pipes?
|
Freezing guidelines are for copper pipes. Any other type of pipe will need at least 25% more product and time (depending on conditions). Our refrigerant will not freeze Polybutylene pipes.
|
What is the product weight of your Arctic Spray canisters?
|
ZE1 has a fill of 150ml - 101g canister weight and 176g of product, with a total weight of 277g.
ZE2 has a fill of 300ml - 125g canister weight and 356g of product, with a total weight of 481g.
A full can of ZEP1 weighs approximately 850g, with a canister weight of approximately 250g. The average fill fluid/gas volume is 600g.
|
What is the shelf life for ZE1, ZE2 & ZEP1?
|
All three products have a shelf life of 2 years, if stored and used correctly.
|
The pipe freezing instructions state that the jackets are different colours but are all blue?
|
The outside of the jackets are blue, the Velcro on the inside is coloured.
|
Does the ZECOM kit come with 3 pieces of nylon tube? The image on the instructions shows three pieces.
|
No, the kit comes with two pieces of nylon tube (NTB04). This is designed to be cut if required.
