25LB R438A Refrigerant Freon for Air Conditioners – Steel Cylinder Packaging Tank-Quality Guarantee

Description

R-438A Refrigerant (MO99™)

R-438A is a versatile, non-ozone depleting HFC blend designed as a direct retrofit replacement for R-22 in existing residential and commercial air conditioning and refrigeration systems. It offers similar performance with zero ODP and is compatible with mineral oil in most cases.

Key Benefits

• ✅Easy R-22 Retrofit
  Designed for direct drop-in replacement in most R-22 systems with minimal changes.
• ✅Mineral Oil Compatible
  Works with existing mineral oil (MO), alkylbenzene (AB), and POE lubricants — no oil change required in most cases.
• ✅Zero Ozone Depletion
  ODP = 0 and non-flammable (ASHRAE A1 safety class).
• ✅Similar Performance to R-22
  Close capacity, pressures, and efficiency — minimal adjustments needed for TXV or setpoints.
• ✅Versatile Applications
  Suitable for air conditioning, medium-temperature, and low-temperature refrigeration systems.

Specifications

• • Composition: R-125 (45%), R-134a (44.2%), R-32 (8.5%), R-600 (1.7%), R-601a (0.6%)
• • Boiling Point: -42°C to -44°C (approx. -44°F)
• • Global Warming Potential (GWP): ~2,059 – 2,265
• • Ozone Depletion Potential (ODP): 0
• • ASHRAE Safety Class: A1 (Non-flammable, low toxicity)
• • Type: Zeotropic blend with moderate temperature glide

Applications

• ✅Residential and Commercial Air Conditioning Systems
• ✅Medium and Low Temperature Refrigeration
• ✅Direct Expansion (DX) Systems, Chillers, and Heat Pumps
• ✅Retrofit of existing R-22 systems (not suitable for flooded evaporators or centrifugal compressors)
