About R508B Refrigeration Gas

R508B is an HFC/PFC blend refrigerant, primarily used for ultra-low temperature refrigeration (like medical freezers, environmental chambers, below -40C) as a replacement for R-503 and R-13, offering better performance than R-23 due to lower discharge temperatures and higher capacity. Key properties include a low boiling point (around -87.4C), an A1 safety classification, requiring POE oil, and a high Global Warming Potential (GWP), making its use regulated.

Key Details of R508B

Type: Azeotropic blend of HFC (R-23) and PFC (R-116).
Applications: Medical freezers, environmental test chambers, and other very low-temp systems.
Replaces: R-13, R-23, R-503.
Temperature Range: Operates effectively down to -101C (-150F).
Oil Compatibility: Requires Polyol Ester (POE) oil.
Safety (ASHRAE): A1 (Non-flammable, low toxicity).
Performance Benefits: Lower compressor discharge temperatures than R-23, increasing system reliability and compressor life; higher cooling capacity than R-13.
Environmental Impact: High GWP (around 13,396), subject to regulations like the EU's F-Gas Regulation.

Physical & Chemical Properties (Approximate)

Molecular Weight: 95.4 g/mol.
Boiling Point: ~ -87.4C (-125.3F).
Critical Temperature: ~ 11.2C (52.2F).
Critical Pressure: ~ 3.93 MPa (570 psia).

Safety & Handling

Frostbite: Liquid contact can cause severe frostbite due to rapid evaporation.
Suffocation Risk: Vapors are heavier than air and can displace oxygen in confined spaces.
Cardiac Sensitization: High exposure can affect the heart.
Regulations: Recovery and reclamation are mandatory in many regions due to its high GWP.
