Product Overview
R22 refrigerant cans are small, disposable, hermetically sealed containers designed for convenient and portable use in air conditioning and refrigeration servicing. These cans are ideal for field technicians, maintenance crews, and small-scale refrigeration applications where portability and ease of handling are essential.
R22 (Chlorodifluoromethane) is a widely used HCFC refrigerant known for its stable chemical properties and excellent thermodynamic performance. In can form, it is typically used for topping up systems, conducting leak tests, and servicing small to medium-sized refrigeration equipment. Available in various net weights from 100g to 1,000g, these cans are suitable for a wide range of applications.
⚠️ Important Note: R22 is an HCFC refrigerant and is being phased out globally under the Montreal Protocol. Please check local regulations before purchase, as its production and use are restricted or prohibited in many markets.
