Refrigeration, RFQ & Procurement Management FAQ

Question 1

What is industrial refrigeration, and how is it different from commercial cooling?

Accepted Answer

Industrial refrigeration covers large-capacity cooling for cold storage warehouses, food processing, blast freezing, IQF lines and process cooling — typically ammonia or CO₂ plants, glycol chiller loops or large packaged systems. Commercial cooling (display cases, small cold rooms) uses smaller self-contained units. The procurement process differs too: industrial systems are engineered to order, so the buyer's brief and RFQ quality determine whether quotes are comparable.

Question 2

Which refrigerant should a new cold storage facility use — ammonia, CO₂ or HFO blends?

Accepted Answer

It depends on capacity, temperature class, local regulation and available service skills. Ammonia (R717) dominates large plants for efficiency and zero GWP but needs trained operators and safety systems. CO₂ transcritical systems suit medium-to-large facilities, especially in cooler climates. HFO/HFC blends fit smaller packaged equipment but face phase-down schedules in many markets. State your constraints in the RFQ and let suppliers propose — then compare efficiency at your actual operating conditions.

Question 3

How do I estimate the cooling capacity my facility needs?

Accepted Answer

Start with the product load (throughput × temperature drop × specific heat), add transmission through walls and roof, infiltration through doors, and internal loads (people, lights, forklifts, fans). Our cold storage calculators give a planning-grade estimate in kW; final sizing belongs to the supplier's detailed design. Never let a supplier size the plant without seeing your product and throughput data.

Question 4

What temperature class should I specify — chilled, frozen, blast or pharma?

Accepted Answer

Chilled rooms hold 0 to +4 °C for fresh produce and dairy; frozen storage holds −18 to −25 °C; blast freezing pulls product core temperature down fast and needs far higher capacity per tonne; pharmaceutical storage needs validated 2–8 °C or frozen ranges with monitoring and alarms. The temperature class drives compressor selection, insulation thickness and cost — define it before requesting quotes.

Question 5

What should an industrial refrigeration RFQ include?

Accepted Answer

State the same assumptions to every bidder: capacity in kW or tonnes of refrigeration, evaporating and condensing temperatures, refrigerant preference or constraints, noise and footprint limits, applicable standards, delivery terms, warranty and documentation expectations. Add a completeness checklist — equipment schedule, installation scope, commissioning, training, spare parts. Missing line items are the most common reason a low quote becomes an expensive project.

Question 6

Why do refrigeration quotes for the same project differ so much?

Accepted Answer

Usually because suppliers priced different scopes: one includes civil works and installation, another prices equipment only; one assumes a central ammonia plant, another packaged units. A structured RFQ that fixes the assumptions for every bidder is the single most effective way to make quotes comparable line by line.

Question 7

How many suppliers should receive the RFQ?

Accepted Answer

For projects above USD 250K, three to five qualified suppliers is a practical range: enough for competitive tension, few enough that each proposal gets a serious evaluation. Qualification matters more than count — a supplier without a service network in your country or experience in your temperature class should not be on the list.

Question 8

Should the RFQ ask for a turnkey price or equipment-only price?

Accepted Answer

Ask for both, itemized. Turnkey pricing (design, equipment, installation, commissioning) shows the real project cost; equipment-only pricing lets you compare the core plant across bidders and price local civil and electrical works separately. A comparison matrix with both views exposes scope gaps immediately.

Question 9

What does procurement management mean for a cold chain project?

Accepted Answer

Controlling the flow from brief to contract: writing the scope, issuing the RFQ, collecting proposals, normalizing them into a comparison matrix, clarifying deviations, checking references, and documenting the final selection. For projects above USD 250K, a structured process typically saves more than any single negotiation.

Question 10

How should I evaluate refrigeration proposals beyond price?

Accepted Answer

Compare energy performance (COP at your operating conditions, not nameplate), refrigerant charge and regulatory exposure, service network coverage in your country, lead time, spare-parts commitment, and the supplier's track record on similar facilities. A simple scoring matrix across these criteria makes the decision defensible to management and financiers.

Question 11

How does ColdMatch fit into the procurement process?

Accepted Answer

ColdMatch is buyer-side and supplier-neutral. You submit one project brief; a human reviewer prepares it; qualified refrigeration suppliers are approached only after the project is understood. You receive comparable proposals and keep full control of the decision. ColdMatch does not lend, does not rank suppliers for payment, and does not replace your engineering review.

Question 12

What are the most common procurement mistakes in cold storage projects?

Accepted Answer

Buying on capital price alone while ignoring lifetime energy cost; accepting a quote without a completeness checklist; letting the supplier define the scope; skipping reference checks on similar facilities; and signing before deviations from the RFQ are documented in writing. Each is avoidable with a structured brief and a comparison matrix.
