Start Free RFQAmmonia refrigeration suppliers: is this the right procurement route?
Ammonia (R717) is the efficiency benchmark for large industrial refrigeration. ColdMatch is a B2B procurement platform: we compare qualified ammonia refrigeration suppliers against your project brief and return normalized quotes — we do not manufacture, install or lend.
Best for
- Industrial cold storage, food processing, dairy, brewery and distribution sites above ~300 kW
- Low-charge packaged NH₃, central two-stage plants or NH₃/CO₂ cascade systems
- HFC-to-NH₃ conversion projects needing compliant retrofit scope
- Buyers who want multiple vetted quotes compared on lifecycle cost, not just headline CAPEX
Not ideal for
- Small commercial split systems or domestic refrigeration
- Sites with no trained ammonia operators and no budget for training/PSM
- Urban locations where total charge limits rule out traditional pumped NH₃
- Emergency repair or spare-parts procurement only
Information checklist before an RFQ
- Total cooling duty (kW/TR) per suction level
- Target evaporating and condensing temperatures or product loads
- Ambient design conditions and plantroom location/constraints
- Applicable safety code and PSM/RMP threshold expectations
- Redundancy, heat-recovery and monitoring requirements
- Power supply, water availability and heat-rejection method
- Target commissioning date and budget range
How does ColdMatch qualify ammonia refrigeration suppliers?
We screen suppliers on IIAR/EN 378 design experience, reference projects in similar climates and duties, pressure-vessel certification, PSM/RMP documentation capability, financial stability, spare-parts logistics and after-sales coverage in the buyer's country. Only suppliers who can deliver the full scope you define are invited to quote.
What is included in a comparable NH₃ plant quotation?
A normalized quote covers compressor package, condenser, evaporators, vessels and pipework, controls and monitoring, safety detection and ventilation, installation and commissioning, performance guarantees, documentation (P&IDs, HAZOP, PSM/RMP), training and warranty. ColdMatch flags exclusions so you see which supplier covers what.
Can ColdMatch manage HFC-to-ammonia conversion projects?
Yes. We source conversion feasibility studies and turnkey EPC scope from specialists who have delivered HFC-to-NH₃ retrofits. Typical scope includes a new low-charge NH₃ package, secondary glycol or CO₂ distribution to reuse existing evaporators, controls upgrade and machine-room compliance work.
- •Low-charge packaged NH₃: 100–500 kW
- •Single-stage industrial plant: 300 kW–1 MW
- •Two-stage frozen-storage plant: 1–3 MW
- •Central NH₃/CO₂ cascade or heat-recovery plant: 3 MW+
Exact system sizing depends on required temperature, ambient climate, product load and turnover rate, door openings, insulation specification, storage duration, redundancy level and operating hours. ColdMatch does not manufacture equipment — we help industrial buyers compare suitable suppliers and technologies against project-specific technical and commercial requirements.
- •Country, project location and site status (greenfield or existing building)
- •Application and product stored or processed
- •Required temperature range and any humidity requirement
- •Storage capacity (m², m³ or pallet positions) and daily throughput
- •Ambient/design climate conditions at site
- •Available power supply and backup or redundancy requirement
- •Preferred refrigerant, if already defined by policy or regulation
- •Indicative budget range and target commissioning date
- •Cooling duty per suction level and target evaporating temperatures
- •Ambient design conditions and plantroom constraints
- •Safety code jurisdiction (IIAR-2, EN 378, PSM/RMP)
- •Redundancy, heat-recovery and monitoring requirements
