Found Leak ... But Fix May Be Tough

Three products from Cliplight are designed to seal refrigerant leaks in a range of applications.
Sealing leaks continues to be of critical concern in light of possible fines and rising costs of refrigerants. One challenge is to find the leaks; the other is to create an effective seal.

In the latter effort, Toronto-based Cliplight Mfg. has introduced a line of products featuring three custom formulas for systems ranging from small refrigeration appliances up to residential central a/c units and large multiple ton chillers.

The product line, called Super Seal, is designed to seal undetectable or inaccessible micro leaks in condensers, evaporators, and piping from the inside out. Injection is a one-step process of drawing the system refrigerant into a vacuum-packed can for mixing and dispensing the sealant throughout the system, thus eliminating compatibility considerations. Super Seal is compatible with all refrigerants and oils, according to the company.

The manufacturer said that conventional leak detection attempts can be tried, but if they prove unsuccessful Super Seal can be injected into a system that is clean and moisture-free. The patented low viscosity, particle-free formula is designed to flow freely throughout the system without affecting valve cores, driers, compressors, or other components. Once Super Seal and the refrigerant leak out a hole of 300 microns or smaller, a chemical reaction crystallizes it around the hole during exposure to atmospheric moisture, and then forms a seal.

The company has three products in the line: Super Seal 3-Phase™ commercial and industrial strength formula for 5-ton systems and larger, Super Seal HVACR™ for most residential a/c systems 1-½ to 5 tons, and Super Seal ACR™ designed for small air conditioning and refrigeration systems ranging from 230 Btuh up to 18,000 Btuh or maximum 1-½ tons.

Each Super Seal product comes with a disposable charging hose. The manufacturer said the product can be reclaimed and separated in the refrigerant recycling-cleaning process.
