Spectrolines Approach to Sealing Leaks

Spectroline, one of the worlds leaders in leak detections product Cool Seal is a great method for repairing problematic refrigerant leaks and safeguards systems against future leaks.

For both experienced AC/R maintenance contractors and businesses running the air conditioning systems refrigerant leaks are a time-consuming and costly business.  Leaks can take a long time in find and repair especially in the puncture site if its very small or hidden from view. For the company operating the system, refrigerant leaks cost money, damages the environment, increase the carbon footprint and reduces the efficiency, reliability and lifespan of the system. When the air conditioning system has reduced pressure and refrigerant levels the system has to work harder and uses much more energy to maintain the same output.

Problematic leaks

Most AC/R service engineers recognise that there are a range of leaks that are much more problematic than others, these leaks are harder to detect, harder to find and harder to fix. In some cases, service engineers will know that real leaks definitely exist in systems when pressure levels reduce. Small leaks that discharge minute levels of refrigerant can be almost impossible to locate. One of the most frustrating things is spending hours with an electronic detector trying to look for a leak in the a/c system that you can never find.

A group of AC/R service engineers came up with a list of the most annoyed, disliked and difficult to find refrigerant leaks.

  1. Pinhole leaks: tiny, microscopic, hairline cracks or leaks releasing very small traces of refrigerant, which are very hard to locate
  2. Intermittent leaks: slow, sporadic, on/off leaks
  3. Hidden leaks: leaks within concealed pipework that cannot be accessed easily
  4. Multiple leaks: numerous small leaks within the same system (fix one, and then discover there’s another somewhere else)
Large leaks are more obvious and easy to locate and repair because there are obvious signs the refrigerant is escaping and detectors can find.

 

The solution for small, hard to find and fix leaks. 

Cool Seal

Spectroline formulated a type of leak sealant called Cool Seal, designed to fix all four of the examples engineers gave.
With advanced engineering, Spectroline recommends that as a preventative maintenance measure because its formula means its continually safeguards the system against more leaks.
Cool Seal is composed of aliphatic hydrocarbon compounds and is safe, non reactive, easy to use and is non-polymer which means it doesn’t harden when inside the system.
A AC/R service engineer injects the Cool Seal liquid in the low pressure service point using the EZ-Ject Kit. This allows it to circulate harmlessly throughout the system.
Now when a break or leak does occur, internal pressure within the system causes refrigerant and oil molecules to move to the leak site to be expelled.

Cool Seals single, double and triple aliphatic compounds are larger and longer then standard molecules which makes them accumulate and group together a the leak site in a process known as “flocculation”.

This flocculation, or build up of larger, complex molecules directly over the leak site physically blocks and seals the leak, preventing the much smaller refrigerant or oil molecules from escaping.
​

Online polymer-based leak sealant that react with moisture or oxygen at the leak site to form a hard patch, the most important aspect of Cool Seal Most is the entirely polymer-free and oil soluble formula means there is no hardening whatsoever and no troublesome clogs because no such chemical reaction takes place.

Preventative maintenance

When you have Cool Seal circulation in an a/c system, it is always guarding and ready to fix future leaks which makes it ideal to use as a preventative maintenance measure.
Cool Seal can be safely introduced solely as a preventative method for sealing leaks that havent happened yet  in air conditioning systems that aren’t already leaking refrigerant.
Cool Seal is safe to use in all popular AC/R systems including high-pressure R410A systems, and it quickly seals the most problematic leaks up to 0.3mm in compressors, condensers, evaporators, O-rings, hoses etc.
Cool Seal meets ASHRAE 97 standards for chemical stability and is especially useful as a low cost alternative to expensive replacement parts especially in older AC/R systems.
