COOL5® WINTER FULL KIT AC REPAIR is the world’s first and innovative product with a unique action and composition, whose formulation has been developed in such a way that the product contained in one can is equivalent to the entire service procedure used in specialised workshops.

It is a 5-in-1 preparation, which means that in a single application, 5 valuable components are added to the car’s A/C system: dehumidifiers, oils, sealants and gas, improving operation, increasing the efficiency of cooling as well as heating the system, and thus prolonging the life of the A/C system.
The formulation volume has been matched to 95% of the systems found in cars circulating throughout Europe.

The main objective of the COOL5 LAB chemists and technologists was to create a self-application formulation that mirrors the entire service procedure used in specialised workshops. In the first step, the system is dried. Thanks to the ProDry additives contained in COOL5® FULL KIT AC REPAIR – the A/C system is chemically dried from harmful moisture particles contained in the system. Step two is to seal the aluminium components, which corrode over the years and form microperforations that are a source of micro leaks and cavities. The third step is to seal the rubber components, mainly the O-rings and gaskets in the cooling system. The fourth, very important step is to lubricate the system and the compressor with the correct dose of synthetic oil, which is recommended by most A/C compressor manufacturers e.g: Denso. After carrying out the four steps described in this way – the loss of gas in the cooling system is topped up with an equivalent of R134a gas, which is lighter than the original refrigerant but, above all, is a fully ecological gas that does not contribute to the greenhouse effect. Therefore, the use of COOL5® WINTER FULL KIT AC REPAIR can be considered the equivalent of a full service procedure in a specialised workshop.

Thanks to the innovative COOL5® FULL KIT AC REPAIR, the A/C system is chemically dehumidified from harmful moisture particles contained in the system, which freeze in the system in winter and can contribute to compressor damage. COOL5® FULL KIT AC REPAIR is the first and only product on the market which dries the system. without performing a vacuum and without specialised equipment. As a result of this chemical process, the water molecules are bound and transformed into synthetic oil. The formulation has been developed in such a way that the product contained in one can is equivalent to the entire service procedure used in specialised workshops.

Yes – the air conditioning system should and should be cared for all year round. Even in the winter season.
COOL5 LAB has developed a winter service kit as a perfect complement to the maintenance and recommended service interventions that prolong the life of the A/C system – providing the system with all the necessary ingredients for proper and trouble-free operation of the entire cooling system. In addition, by purchasing the set: COOL5 WINTER SAFETY SET you gain three (3) unique additional preparations to improve comfort, visibility as well as the safety of your car in winter (!)
A PROPERLY OPERATING air-conditioning system warms up the vehicle interior in winter much faster than the engine heater, which in some modern diesel engines takes up to 25 minutes to reach heating efficiency. An additional benefit of using the COOL5 Winter Safety Set is the removal of harmful fungi, mould and viruses from the vehicle interior thanks to the effective COOL5 Desinfection BOMB.
