Propane R290, also known as isobutane in some contexts, is a natural hydrocarbon refrigerant gaining significant traction in the global market. Its excellent thermodynamic properties, coupled with a negligible environmental impact, make it a compelling alternative to traditional synthetic refrigerants. As a chemical supplier specializing in refrigerants, we aim to provide clarity on R290's characteristics and safe usage.

The fundamental properties of Propane R290 are key to its effectiveness. With the chemical formula C3H8 and CAS number 74-98-6, it is a highly pure substance, typically available with a purity of ≥99.5%. Its molecular weight is approximately 44.9 g/mol. Crucially, R290 boasts an ultra-low Global Warming Potential (GWP) of around 0.01 and an Ozone Depletion Potential (ODP) of 0. This environmental profile is a significant advantage, especially as regulations mandate the phase-down of high-GWP refrigerants.

In terms of physical properties, R290 has a boiling point of -42.1°C and a critical temperature of 96.7°C. These characteristics make it suitable for a range of refrigeration and air conditioning applications. Its high energy efficiency means that systems utilizing R290 often consume less power, leading to reduced operational costs for users. When you buy R290, you are investing in both performance and economy.

The applications for Propane R290 are diverse and growing. It is widely used in:

  • Commercial refrigeration units, such as display cases and freezers.
  • Residential air conditioning systems.
  • Low-temperature refrigeration applications.
  • Specialized industrial cooling processes.

As a reliable manufacturer and supplier, we ensure our R290 meets stringent quality indices, including low moisture and acidity levels, to guarantee optimal system performance.

Safety considerations are paramount when handling R290 due to its flammability. ASHRAE classifies it as A3, indicating high flammability. However, with adherence to established safety standards and proper system design, including appropriate charge limits and ventilation, R290 can be used safely. Manufacturers must ensure that equipment is designed and certified for use with flammable refrigerants. For those looking to purchase R290, understanding these safety protocols is as important as verifying the product's purity.

By choosing Propane R290, businesses can leverage a high-performance, environmentally responsible refrigerant. Sourcing from a reputable R290 refrigerant supplier in China ensures quality and reliability for your cooling needs.
