Compare Refrigeration Suppliers: Documented RFQ Scorecard

Direct answer: define the operational result and one common design/scope brief before comparing manufacturers. Apply pass/fail requirements first, then score documented capacity, energy basis, scope, commissioning, support and lifecycle cost. Mark unsupported statements unverified; a brand or low price is not proof of fitness for your site.

Which supplier claims require documents before they earn a score?

Use one row per requirement and one column per proposal. Record requirement, supplier response, document/revision, evidence status, exception and reviewer. Set mandatory gates and buyer-chosen weights before comparing prices; do not invent universal weights or substitute a score for engineering approval. Unknown evidence stays unverified, not compliant. First clarify discrepancies through the ColdMatch team when using managed procurement.

What acceptance evidence should be agreed before contract award?

Specify representative loading, product and ambient conditions, instruments, duration, responsible witnesses and pass/fail criteria with qualified engineering and quality personnel. Include temperature mapping, pull-down where required, alarms, defrost and safe power-loss/restart tests. Agree how deviations are corrected and retested. The ASHRAE commissioning resource describes a requirements-led process; it is not a ColdMatch certification. Request drawings, settings, manuals, maintenance/spares lists and operator training. No manufacturer performance, availability, local service or reference is verified by this article.

What is lifecycle cost in industrial refrigeration?

Lifecycle cost (also called total cost of ownership) is the sum of what a system costs to buy, install, run, maintain and eventually replace or decommission over a chosen period. For refrigeration, running and maintenance costs continue for every year the plant operates, so differences in efficiency, reliability and serviceability can outweigh a gap in the initial price. ColdMatch's article on cheapest refrigeration versus lifetime cost explains the principle; this guide shows how to apply it to real proposals.

Why are refrigeration proposals so hard to compare?

Because each supplier fills gaps in the brief differently. One assumes a lower ambient temperature, another a smaller daily intake; one includes electrical works and commissioning, another excludes them; one quotes a two-year warranty on parts and labour, another one year on parts only. Read hidden costs in cold storage quotations for the lines that most often go missing.

Step 1: are all proposals sized for the same duty?

Before looking at price, put each supplier's design basis side by side. If these differ, ask the supplier to re-quote on the common basis rather than adjusting numbers yourself.

If you have not fixed these values yet, the refrigeration load calculator helps you test them; its result is a planning estimate, not a design.

Step 2: is the scope identical?

List every scope item and mark each proposal *included*, *excluded* or *unclear*. Typical lines: insulated panels and doors, refrigeration equipment, piping and refrigerant charge, controls and monitoring, electrical panels and cabling, civil works and floor insulation, transport and duties, installation, commissioning, training, documentation, spare parts, and post-handover support. Every *unclear* becomes a written question to the supplier.

Step 3: which lifecycle cost lines should you compare?

Use the electricity cost calculator to convert each supplier's stated consumption into an annual energy cost at your tariff. If a supplier does not state consumption and its basis, ask for it; an undisclosed assumption cannot be compared.

How do warranty and service scope change the comparison?

Two warranties with the same length can be very different. Compare what is covered (parts, labour, travel, refrigerant), from when (delivery, commissioning or acceptance), the conditions (approved maintenance, original parts) and the response time for faults. Ask who will service the plant locally after handover and how quickly they can attend. A strong service arrangement reduces downtime risk, which belongs in the lifecycle comparison even though it rarely appears as a price line.

Should the refrigerant or system type decide the comparison?

Not on its own. Different refrigerants and system types suit different capacities, climates, skills and rules, and requirements change over time in many jurisdictions. Ask each supplier to explain why their choice fits your site, what it means for service and future compliance, and what safety measures it requires. A qualified local engineer should review the shortlisted designs against the regulations that apply to you before contract award.

Which cold storage specifications should you compare line by line?

Before choosing a system, put these specifications side by side for every proposal. The right column lists what a qualified engineer should confirm — a buyer can collect and compare the data, but cannot sign off the design. The free technical specification builder and proposal comparison matrix help you organise them.

Then convert each offer into a total cost over the same period with the refrigeration TCO calculator. All results are planning estimates, not quotes.

Complete refrigeration RFQ checklist

Include these items in your request so every supplier answers the same questions. The ColdMatch cold storage RFQ checklist gives a printable version.

• Project summary: products, sectors, site country and region, schedule.

• Duty: temperatures, humidity, daily intake, incoming temperature, storage duration.

• Site: peak ambient conditions, available space, building status, access.

• Capacity: pallet positions or tonnes, layout sketch, growth case.

• Utilities: power supply, outage pattern, water, required backup and redundancy.

• Constraints: refrigerant or energy requirements, local service availability, applicable regulations for local review.

• Scope: list of included items and interfaces with other contractors.

• Requested answers: capacity at stated conditions, annual energy estimate and basis, maintenance plan, spare parts list, warranty terms, response times, delivery and installation schedule, commissioning and acceptance tests, documentation and training.

• Commercial: price breakdown, currency, delivery terms, payment schedule, validity period.

How to score proposals after normalising them

Agree weights before opening prices — for example technical fit, lifecycle cost, delivery schedule, service and support, and risk — then score each proposal against the same criteria. Record why each score was given. Procedures such as these are consistent with the value-for-money approach described in public procurement guidance like the World Bank Procurement Framework, even for private buyers.

What should you ask every bidder about controls and service?

• Which controller and monitoring platform is offered, who owns the data and can it be exported?
• Which alarms are included, who receives them and how is escalation tested at handover?
• What is the planned maintenance schedule and the content of each visit?
• Who services the plant locally, what is the guaranteed response time and which critical spares are stocked locally?
• What training and documentation (as-built drawings, settings, manuals) are delivered?

What should you do — and avoid?

• Do normalise duty, scope and assumptions before comparing prices.
• Do apply your own tariff and running hours to each stated energy figure.
• Do compare over one period and one currency.
• Avoid comparing headline prices with different exclusions.
• Avoid scoring claims that have no supporting document.

Which mistakes cost buyers the most?

Illustrative worked example: normalising two bids

*Illustrative only — invented figures to show the method, not market prices or real suppliers.* Assumptions: two bids for the same cold store. Bid A: purchase price 1.00 M (currency units), stated energy 400 MWh/year, one-year parts-only warranty, controls excluded. Bid B: purchase price 1.10 M, stated energy 340 MWh/year, two-year parts-and-labour warranty, controls and monitoring included. Your tariff: 0.15 per kWh; comparison period 10 years; no discounting for simplicity. Normalise: add the price of controls to A (say 0.05 M, obtained by asking the bidder). Energy over 10 years: A = 400,000 kWh × 0.15 × 10 = 0.60 M; B = 340,000 × 0.15 × 10 = 0.51 M. Subtotal: A = 1.00 + 0.05 + 0.60 = 1.65 M; B = 1.10 + 0.51 = 1.61 M — before maintenance, warranty difference and downtime risk. The result can reverse with a different tariff, running hours or financing cost; the method, not the winner, is the point. Use the refrigeration TCO calculator with your own figures.

Summary

• Same duty, same scope, same assumptions — then compare.
• Convert every stated energy figure into cost at your tariff.
• Compare controls, service, spares and warranty in writing.
• Use one period and currency for lifecycle cost.
• Ask a qualified engineer to review the shortlist before award.

How does ColdMatch help you compare proposals?

After defining the product, route, capacity, temperatures, site and operating outcome, you may optionally prepare an RFQ. ColdMatch reviews the request, coordinates suitable supplier outreach and organises responses for comparison; there is no direct buyer-to-supplier handoff. Buyer procurement is free, with typical USD 250K+ commercial B2B scope. ColdMatch does not manufacture, install or lend and guarantees no savings, performance, availability or approval. Any later exploration of independent external financing is optional and requires consent; no request is automatically sent to a bank or supplier. You can use this checklist without submitting anything.
