R454A refrigerant is a HFO low GWP (239) substitute for R404A in new devices. Its features as a substitute for R404A are in optimal balance; It has better performance and higher cooling power as a substitute. GWP‘s decline here is a staggering 94%.
R454A refrigerant has more R32 to ensure better performance
Refrigerant R454C’s GWP value is even lower, but R454A has more R32 refrigerant to ensure better performance.
Advantages of R454A over R404A
- Low GWP (239)
- ODP zero (0)
- Better performance
- Higher cooling power
- Very close to the R404A features – easily convertible to existing applications, minor changes
- Can be removed in case of leakage
- Not toxic and slightly flammable (ISO / ASHRAE 2) A2L
- Allows a minimum fill value of over 1.7 kg (e.g. ISO 5149 or EN 378)
R454A refigerant applications and usage
Low and medium temperature commercial and industrial cooling. For example, supermarkets, decentralized systems: coolers, freezers, preparatory facilities. Condensing units for eg food services, cold stores and independent cooling systems. Also suitable for cooling during transport.
