The pressures driving demand for indoor R290 cooling
Regulation is changing and sites are getting tighter. Operators need cooling that works indoors, fits the space they have, and is built for what's coming next.
F-Gas regulation changes take effect from 1st January 2027. Planning your refrigerant strategy now avoids costly retrofits later.
Many operations can't site a chiller outdoors. Roof access, planning and pipe runs make external units impractical.
Teams need confidence that today's investment will still be compliant and serviceable years down the line.
Production layouts change. Cooling needs to move and adapt without major civils or external plant.
Built around real operational challenges
The RC4-1 R290 wasn't designed in isolation. It was developed in response to the everyday problems our customers face when external chillers simply aren't an option.
- Designed around real operational challenges
- Built for indoor process environments
- Developed for smaller operational spaces
- Designed to comply with future F-Gas regulations
- Built using less than 150g refrigerant charge
- Suitable for environments where external chillers are impractical
Built for indoor process environments
From plastics to laboratories, the RC4-1 R290 is at home wherever reliable indoor cooling matters.
Engineered advantages, end to end
Engineered to run safely inside process and production environments.
Built around upcoming F-Gas requirements so it stays viable for years.
Designed for smaller operational spaces where floor area is tight.
Less than 150g of R290 — a naturally low-GWP refrigerant.
Non-ferrous chilled water circuit for cleaner, more reliable operation.
Built to adapt as your production layout and demands change.
Developed and validated by Refcool's own engineering team.
Designed and built in the UK with specialist cooling know-how.
