This kit includes everything you need to recharge a standard window unit that had R22 or an R22 replacement refrigerant in it. There are 2 cans of R290 and a can tap with gauge along with adapters, goggles, oil analyzer, a thermometer and instructions. This refrigerant is non global warming - it does not contain ingredients that cause ozone depletion.
R290 operates at lower head pressures and offers colder air and improved performance compared to R22. This refrigerant will extend the life of a system because of the lower head pressures. R290 refrigerant requires approximately 1/3 the amount of the original charge in the system and must be charged as a liquid.
R290 Refrigerant contains an Orange Scent which aids in leak detection and is officially marketed and sold worldwide as a direct replacement for R22 except for in the United States where regulations prohibit officially marketing it as such. R290 is flammable and shouldn't be brought into contact with a flame.
