ClimaPure STOP LEAK Can - Anti-Leak Solution for Air Conditioning Systems

The ClimaPure StopLeak Can - Anti-Leak Solution for Air Conditioning Systems (Reference: CPSTLEAK) is a major innovation in the preventive maintenance of refrigeration installations. This 113 gram technical solution is specially formulated to treat effectively the minor leaks that affect the performance and the energy efficiency of modern air conditioning systems. Compatible with a wide range of refrigerants, this product has become an essential tool for refrigeration professionals and facility managers.

Practical applications and benefits

ClimaPure StopLeak finds use in an impressive variety of technical contexts. For automotive maintenance technicians, this solution makes it possible to deal quickly with evaporator and condenser leaks without fully removing the dashboard. Commercial building managers find in it an economical way of maintaining the performance of their centralised installations by treating micro-leaks preventively at seals and metal fittings.

In the residential sector, this product proves particularly effective on heat pumps and domestic air conditioning units. Refrigeration installers use it to secure their work and reduce call-backs linked to post-installation leaks. The ability to treat systems containing between 1 and 2.3 kg of refrigerant covers the majority of domestic and light commercial applications.

Technical innovation and compatibility

The advanced formulation of ClimaPure StopLeak is based on new-generation reactive polymers that solidify only on contact with atmospheric moisture and oxygen. This technology ensures that the product stays liquid inside the refrigeration circuit and forms a tight seal only at the exact point of the leak. This selectivity avoids any risk of internal blockage or of damage to sensitive mechanical components.

The product offers wide compatibility with modern refrigerants, including HFCs, HCFCs and the new ecological fluids. This versatility allows it to be used in systems emptied of older CFCs during retrofit operations. The stable chemical formula withstands the variations in temperature and pressure typical of refrigeration cycles, ensuring lasting effectiveness over time.

Application procedure and implementation

Applying ClimaPure StopLeak follows a rigorous technical procedure within the reach of qualified professionals. The first step is to identify and locate the leak precisely using an electronic leak detector or UV tracer products. The system must be running normally with a refrigerant charge sufficient to let the product circulate.

Injection is carried out on the low-pressure side through the standard service fittings. It is essential to respect the recommended dose: one can effectively treats systems with a charge of 1 to 2.3 kg. For larger leaks requiring several cans, leaving 24 hours between applications allows optimal polymerisation. The system must run continuously for at least 30 minutes after injection to ensure even distribution.

Optimisation strategies and product synergies

To get the most out of ClimaPure StopLeak, experts recommend combining it with a UV leak detector for an accurate prior diagnosis. Using it together with high-quality refrigeration oils improves the circulation of the product and optimises the formation of the sealing joint.

A preventive approach consists in including this treatment in planned maintenance programmes, particularly ahead of periods of heavy demand (the summer season for air conditioning). Technical managers should avoid the common mistake of applying it to major leaks: ClimaPure StopLeak effectively treats leaks that do not cause a complete loss of charge in under 3-4 weeks.

For commercial vehicle fleets, adding this product to mobile maintenance kits considerably reduces the downtime caused by air conditioning breakdowns. Maintenance managers will note that compliance with environmental regulations, in particular the French decree of 4 July 1992, remains essential during any work on refrigeration circuits.
