Our F-Gas certified engineers provide comprehensive R448A refrigeration services for businesses throughout London and the M25 area. Whether you require new equipment installation, routine maintenance, emergency repairs, or scheduled servicing, we are equipped to ensure your commercial refrigeration systems operate efficiently and compliantly.
R448A, marketed as Solstice® N40, is a non-flammable HFO/HFC blend refrigerant commonly used as a lower Global Warming Potential (GWP) alternative to R404A and R507A in various commercial refrigeration applications. Its properties make it suitable for both medium and low-temperature systems, offering a balance of performance and environmental responsibility. We work with all types of R448A systems, ensuring professional and reliable service.
Understanding R448A Refrigerant
R448A is a blend composed of R32 (26%), R125 (26%), R134a (21%), R1234yf (20%), and R1234ze(E) (7%). This composition gives it a GWP of 1387, which is significantly lower than R404A's GWP of 3922. This makes it an attractive choice for new installations and for retrofitting existing systems, aligning with evolving environmental regulations.
Its thermodynamic properties are similar to R404A, often requiring minimal system modifications when used as a retrofit. This includes comparable pressures and temperatures, making the transition smoother for many commercial refrigeration setups. R448A is designed for direct expansion systems and performs effectively across a range of operating conditions.

We carry a range of common parts and have access to a wide network of suppliers, allowing us to resolve most issues promptly. Whether it's a refrigerant leak, compressor failure, control system malfunction, or any other operational problem, we provide reliable repair solutions.
Our 24/7 emergency callout service ensures that critical refrigeration failures are addressed without delay, safeguarding your perishable goods and maintaining business continuity.
Retrofitting to R448A Refrigerant
Many businesses are considering retrofitting their older R404A or R507A systems to R448A to comply with F-Gas regulations and reduce their environmental footprint. Our F-Gas certified engineers can assess your existing system and advise on the feasibility and requirements for a successful R448A retrofit.
While R448A offers similar properties to R404A, careful consideration of oil compatibility, TXV adjustments, and system flushing is often necessary for an optimal retrofit. We ensure that all necessary modifications are performed professionally to maximise system performance and longevity with the new refrigerant.
- Assessment of existing R404A/R507A systems for R448A suitability
- Professional refrigerant recovery and replacement procedures
- System adjustments and component checks for R448A compatibility
- Compliance with F-Gas regulations for refrigerant handling
Frequently asked questions
What is R448A refrigerant?
R448A, also known as Solstice® N40, is a non-flammable, zeotropic HFO/HFC blend refrigerant with a lower Global Warming Potential (GWP) of 1387. It is commonly used as a replacement for higher GWP refrigerants like R404A and R507A in various commercial refrigeration applications.
Why should I consider R448A for my commercial refrigeration?
R448A offers a significant reduction in GWP compared to older refrigerants like R404A, aligning with environmental regulations and F-Gas phasedowns. It also provides good energy efficiency and is suitable for both medium and low-temperature applications, making it a sustainable choice for new installations and retrofits.
Can R448A be used to retrofit older R404A systems?
Yes, R448A is a common retrofit option for R404A and R507A systems due to its similar operating pressures and temperatures. However, a professional assessment by F-Gas certified engineers is crucial to ensure compatibility, address oil changes if necessary, and optimise system performance for the new refrigerant.
Do you offer emergency breakdown services for R448A systems?
Yes, we provide 24/7 emergency callout services for R448A commercial refrigeration systems experiencing breakdowns or critical faults. Our engineers are equipped to diagnose and repair issues promptly to minimise downtime and protect your valuable stock.
How often should my R448A refrigeration system be serviced?
The frequency of servicing depends on the system type, usage intensity, and F-Gas regulations regarding refrigerant charge size. Typically, annual or bi-annual preventative maintenance is recommended to ensure optimal performance, detect leaks, and comply with F-Gas requirements. Our engineers can advise on a suitable schedule for your specific equipment.
