Description
Refrix R‑404A Refrigerant Gas
Refrix R‑404A is a near-azeotropic HFC blend engineered for high-performance, low-temperature refrigeration systems. Offering zero ozone depletion potential (ODP = 0) and consistent thermodynamic behavior, it is ideal for commercial and industrial freezers, cold storage, transport refrigeration, and more. It delivers performance characteristics similar to R‑502, making it an industry-standard solution for sub-zero environments.
Key Features:
-
✅ Zero Ozone Depletion (ODP = 0)
-
✅ Stable Performance in Low-Temperature Conditions
-
✅ ASHRAE Safety Class A1 (Non-flammable, Non-toxic)
-
✅ Excellent Cooling Efficiency for Sub-Zero Applications
-
✅ Compatible with R‑502 system retrofits (with modifications)
-
✅ Globally Accepted and Widely Available
Applications:
| Industry / Sector | Typical Uses |
|---|---|
| Commercial Refrigeration | Supermarket freezers, walk-in chillers |
| Cold Storage | Ice cream, meat, seafood storage |

FAQs
1. Can R‑404A replace R‑502 directly?
Yes, R‑404A is designed to replace R‑502 in existing systems, but you must retrofit components like lubricants and seals, and ensure full system evacuation.
2. What type of oil is used with R‑404A?
Only POE (Polyolester) oil is compatible with R‑404A. Mineral oil or alkylbenzene oils are not suitable and must be replaced during retrofitting.
3. Is R‑404A safe to use in food industry applications?
Yes, R‑404A is non-toxic and non-flammable (ASHRAE A1), making it safe for refrigeration systems used in food processing, cold chains, and transport.
