Ammonia refrigeration RFQ template: required inputs, document checklist, one-click copy

1. Why the design basis comes first

Most ammonia tenders fail before a single price is quoted: bidders receive an incomplete brief and each assumes a different plant. The template's first three sections exist to prevent that.

• Design ambient and altitude size the condenser — a bidder assuming the wrong one looks cheapest
• Duty per suction level with evaporating temperatures forces every bidder to size the same plant
• A stated maximum charge lets bidders choose the right architecture before pricing, not after award
• Redundancy and heat-recovery expectations stated up front remove the most common scope gaps

2. Safety scope is a line item, not an assumption

Ammonia safety scope is where cheap quotes are simply smaller quotes. The template makes every safety element explicit so it is priced, not discovered later.

• Named design code: IIAR-2, EN 378, ISO 5149 or local equivalent
• Detection layout, emergency ventilation and relief discharge routing as stated scope
• PSM/RMP or Seveso documentation support where thresholds apply
• HAZOP participation and commissioning safety tests included in the priced scope

3. The document checklist is what makes bids comparable

Every bidder returns the same six document groups, so you compare evidence — not brochures.

• Track record: reference plants of comparable duty and climate, with contactable owners
• Compliance: pressure-vessel certification, welding qualifications, country-valid licences
• Performance: compressor selection printouts at your duty, part-load COP, energy at your tariff
• Commercial: itemised exclusions — anything not listed is deemed included

4. From template to comparable proposals

Issue the same document to every bidder, then normalise what comes back before comparing prices.

• Copy the full RFQ in one click, or download it as Word, Markdown or plain text
• Send identical documents to three to five pre-qualified NH₃ suppliers
• Restate every proposal onto the same scope; price the named exclusions back in
• Compare 10-year cost — energy at your tariff, maintenance, overhauls, spares — not headline CAPEX

Best for

Commercial and industrial cold chain projects, typically from USD 250,000 upward: cold rooms, refrigerated warehouses, blast freezers, processing plant refrigeration and distribution hubs.

Not a fit: domestic refrigerators, household or office air conditioning, small repair call-outs, or spare-parts-only enquiries.

Typical cold chain project types

• Fruit, vegetable and horticulture cold storage with pre-cooling
• Meat, poultry and fish chilling plus blast freezing
• Dairy and beverage process cooling
• Pharma and vaccine GDP cold chain (2–8 °C, −20 °C, −70 °C)
• Refrigerated warehouses, 3PL hubs and mobile cold rooms

Cold room vs refrigerated warehouse

A cold room is a single insulated chamber, usually under ~500 m³, serving one process or storage step. A refrigerated warehouse is a multi-zone facility with racking, docks, air locks and a central refrigeration plant, sized by pallet positions and daily throughput rather than by room volume.

What affects project cost

• Storage volume, pallet positions and daily throughput
• Target temperature and ambient design conditions
• Refrigerant choice (NH₃, CO₂, HFC) and plant redundancy
• Panel thickness, doors, air locks and civil works
• Backup power, solar, freight, duties and commissioning

Temperature range checklist

• +12 to +16 °C — bananas, potatoes, curing
• +2 to +8 °C — pharma GDP, dairy, fresh produce
• 0 to +4 °C — meat, fish and chilled distribution
• −18 to −25 °C — frozen storage
• −35 to −40 °C — blast freezing and IQF

RFQ checklist

• Product, temperature and daily intake
• Room dimensions or required pallet positions
• Site location, ambient conditions and power supply
• Backup autonomy and redundancy level
• Budget range, timeline and scope exclusions

Project type cluster

Agriculture and horticulture cold storage

Pre-cooling plus storage for fruit, vegetables and flowers, usually +2 to +12 °C with high humidity control and fast pull-down after harvest. Sized by daily intake in tonnes, not only by room volume.

Meat, poultry and fish cold storage

Chilling at 0 to +4 °C combined with blast freezing at −35 to −40 °C and frozen holding at −18 to −25 °C. Hygienic panels, drainage and separate dirty/clean flows are part of scope.

Pharmaceutical and API cold storage

GDP-compliant 2–8 °C rooms, −20 °C and, for some active pharmaceutical ingredients and biologics, −70 °C. Requires mapping, IQ/OQ/PQ, N+1 refrigeration, backup power and alarm escalation.

Refrigerated warehouse and 3PL distribution

Multi-zone facilities sized by pallet positions, dock doors and daily throughput. Typical scope covers racking, air locks, dock levellers, a central plant and an energy strategy.

Food processing plant refrigeration

Process cooling, chillers, spiral or tunnel freezers and glycol loops integrated with production lines. Usually specified alongside ISO 22000 and HACCP food safety requirements.

Mobile and containerised cold rooms

Plug-and-play 20 ft or 40 ft refrigerated units for seasonal peaks, remote sites and temporary capacity, typically −25 to +8 °C with optional solar or generator support.
