HFC/HFO Refrigerant System Retrofits

HFC/HFO refrigerant system retrofits in Kenya by Refitec Kenya. Professional conversion of R404A and R22 systems to low-GWP refrigerants with genuine parts. Call +254 704 843 613.
Thousands of Kenyan refrigeration systems still run on R404A and other refrigerants scheduled for phase-down, leaving owners exposed to rising gas prices and shrinking supply. Retrofitting to modern HFO blends is a proven, cost-effective upgrade that restores compliance and often improves efficiency without replacing the whole system. Refitec Kenya manages retrofits with factory-grade procedures, from honest feasibility assessment through recovery, component changes, and commissioning, and documents every conversion for the client’s records and future refrigerant planning.

HFC/HFO Refrigerant System Retrofits by Refitec Kenya

Refrigerant regulations are changing worldwide. High global warming potential HFC refrigerants such as R404A are being phased down under the Kigali Amendment, which Kenya has ratified, and older refrigerants such as R22 have already been eliminated from new supply. As these gases become scarce and expensive, retrofitting refrigeration systems to modern HFO blends and other low-GWP alternatives is becoming a commercial necessity for cold rooms, freezer rooms, display cabinets, and process refrigeration. Refitec Kenya carries out professional HFC and HFO refrigerant retrofits for businesses across Nairobi and Kenya.

What a Refrigerant Retrofit Involves

A retrofit is far more than draining one gas and pumping in another. Each refrigerant has its own pressures, temperatures, oil compatibility, and behaviour with seals and components. A professional retrofit follows a disciplined sequence:

1. System assessment. We record the existing refrigerant, compressor type, expansion device, oil type, and operating condition, and confirm the system is leak-free and otherwise healthy enough to be worth converting.
2. Refrigerant selection. We select the appropriate HFO blend, such as R448A, R449A, or R452A as a replacement for R404A, verifying capacity and discharge temperature implications for the specific compressor.
3. Recovery. The existing refrigerant is recovered into certified cylinders for safe disposal or reclamation, never vented to the atmosphere.
4. Component changes. We replace the filter drier, adjust or replace expansion valves where required, change compressor oil to the compatible lubricant, and update labelling and pressure ratings.
5. Charging and commissioning. The system is evacuated to a deep vacuum, charged with the new refrigerant by weight, and commissioned with recorded superheat, subcooling, and current readings.

Benefits of Retrofitting

• Compliance. Systems aligned with the HFC phase-down avoid regulatory risk and refrigerant supply shortages.
• Lower running costs. Modern HFO blends such as R448A and R449A typically deliver measurably lower energy consumption than R404A.
• Future availability. Retrofitting secures access to refrigerants that will remain available for decades.
• Environmental responsibility. Low-GWP refrigerants substantially reduce the climate impact of leaks.

Systems We Retrofit

Cold room and freezer room condensing units, supermarket display cabinets, ice cream cabinets, blast freezers, beverage coolers, and process chillers. We assess each system honestly: where equipment is too old or too worn, we advise on replacement instead of an uneconomical retrofit.

Frequently Asked Questions

Will a retrofit reduce my electricity bill? In most R404A conversions to R448A or R449A, clients see measurable energy savings, though exact results depend on system condition and load; we verify performance after commissioning. How long does a retrofit take? A single condensing unit is typically retrofitted within one day, minimizing downtime; larger systems with multiple units are phased to keep cooling available throughout. Is my old R22 system worth converting? Only if the compressor and components are in sound condition; where equipment is worn, we advise on replacement with a modern system as the more economical path.

Refitec Kenya performs refrigerant retrofits in Nairobi, Thika, Nakuru, Mombasa, and countrywide, with genuine components and documented commissioning records.
