CO₂ refrigeration plant with heat recovery
Free for buyers. Your request goes to the ColdMatch team, who review it and contact suitable suppliers on your behalf. ColdMatch does not manufacture equipment or guarantee compliance.
What the package includes
- CO₂ (R744) refrigeration plant
CO₂ central plant
- Evaporators and unit air coolers
Air coolers matched to each room
- Refrigeration controls and plant management
Plant control, heat-recovery control and remote access
- Temperature monitoring and alarm system
Independent temperature records and alarms
How the parts depend on each other
- Heat recovery only pays off where there is a use for the heat on site — state hot-water or heating demand.
- Hot-climate sites need the supplier to document performance at your ambient design temperature.
Standards and specification basis
- Refrigerant rules in your market (for example the EU F-gas Regulation or US EPA Technology Transitions) — CO₂ itself is a natural refrigerant.
- Pressure-equipment and machine-room safety codes that apply locally.
Best fit for buyers who
- You want a natural refrigerant with a long service life.
- There is a year-round use for recovered heat on site.
- Local technicians are trained on CO₂ systems, or training can be included.
Commercial benefits
- Avoids exposure to future restrictions on high-GWP synthetic refrigerants.
- Recovered heat can replace other heating where there is demand.
Risks to manage
- Hot climates need specific design measures; performance must be documented for your conditions.
- High operating pressures require trained service staff.
Limitations
- Heat recovery adds cost and complexity; it only helps if the heat is used.
- Service capability for CO₂ varies by country.
Documents to request
- Design conditions and capacity at your ambient design temperature.
- Heat-recovery capacity and how it is controlled.
- Safety concept, commissioning records and operator training plan.
Regulatory notes
- Check pressure-equipment approvals and machine-room requirements locally.
- Confirm technician certification rules for CO₂ systems in your country.
Price ranges
No price range is published for this package: costs depend on capacity, site and country, and ColdMatch has no researched, dated range to show. Planning ranges for whole cold stores are on the cost benchmarks page; real prices come only from suppliers’ written offers.
