For engineers, R&D scientists, and procurement specialists in the HVAC and refrigeration sectors, a thorough understanding of refrigerant properties is fundamental. Refrigerant Gas R32 (Difluoromethane, CH2F2, CAS 75-10-5) is a critical component in modern cooling systems, and knowing its detailed specifications and handling requirements is vital for safe and efficient operation. This article provides a technical breakdown of R32, focusing on its key properties and best practices for handling, straight from a reputable chemical manufacturer.

Chemical and Physical Properties: The Science Behind R32

R32 is characterized by several important properties that make it a superior refrigerant:

  • Molecular Formula: CH2F2
  • Molecular Weight: 52.02 g/mol
  • Boiling Point: -51.7 °C at 1 atm. This low boiling point is essential for its function as a refrigerant.
  • Critical Temperature: 78.2 °C. This indicates the temperature above which a gas cannot be liquefied, regardless of pressure.
  • Critical Pressure: 5.808 MPa. This is the pressure at the critical temperature.
  • Specific Heat of Liquid (30°C): 0.31 kJ/(kg•°C). Important for calculating cooling capacity.
  • Ozone Depletion Potential (ODP): 0. This means R32 does not harm the ozone layer, a critical environmental advantage.
  • Global Warming Potential (GWP100): 675. Significantly lower than older refrigerants like R-410A.

These properties contribute to R32's efficiency and environmental profile, making it a preferred choice for discerning HVAC system designers and manufacturers. As a dedicated chemical producer, we meticulously control these parameters during our R32 gas manufacturing process.

Quality Standards and Purity Assurance

The performance and longevity of HVAC systems heavily depend on the quality of the refrigerant used. Our R32 refrigerant typically meets stringent quality standards:

  • Purity: ≥99.8%
  • Moisture: ≤10 ppm. Low moisture content prevents system corrosion and ice formation.
  • Acidity: ≤1 ppm. Acidity can degrade system components.
  • Vapor Residue: ≤100 ppm. Ensures complete vaporization and efficient operation.
  • Appearance: Colorless, no turbid.
  • Odor: No strange stench.

These specifications are critical for ensuring reliable operation and minimizing the risk of system failures. When you buy R32 from us, you are assured of meeting these high-quality benchmarks.

Safe Handling and Packaging for R32 Refrigerant

While R32 is a safer alternative in many respects, proper handling is still crucial. It is classified as a mildly flammable gas, meaning it can ignite under certain conditions, especially when exposed to open flames or high temperatures. Therefore, it must be stored and handled in well-ventilated areas, away from ignition sources.

We offer R32 in various packaging options to suit different industrial needs, including:

  • Disposable cylinders (e.g., 10.9kg/24lb)
  • Recyclable cylinders (e.g., 400L, 800L, 926L)
  • ISO-Tanks for large-scale industrial supply.

As a responsible chemical supplier, we provide clear guidelines on safe handling and transportation. Our commitment extends beyond manufacturing to ensuring the product reaches our clients safely and efficiently.
