High-pressure natural refrigerant systems
CO₂ & Ammonia Refrigeration
CO₂ and ammonia refrigeration systems operate at extreme pressures — CO₂ transcritical systems can exceed 10,000 PSI — and demand a level of specialist knowledge and care that goes far beyond standard refrigeration work. These systems are widely used in large-scale food production, cold storage, and agricultural operations, and the South East's farming communities rely on them to keep produce fresh from field to distribution. Telcius provides installation, repair, and emergency breakdown cover for CO₂ and ammonia refrigeration systems. Our engineers are trained to work safely with these high-pressure natural refrigerants, following strict handling protocols to protect both personnel and plant.
- CO₂ transcritical system installation & repair
- Ammonia (NH₃) system servicing & maintenance
- Emergency breakdown response
- High-pressure system safety compliance
- Agricultural & cold storage applications
- Leak detection & refrigerant management
