Industrial Refrigeration Supplier Comparison: How to Evaluate Quotes Properly

A 20% price gap between two quotations is usually a scope gap, not a discount. Normalising scope before negotiating is where real value is protected.

• Duty at stated design ambient, not nominal catalogue duty
• Compressor and evaporator selection logic
• Control philosophy and part-load behaviour
• Warranty and refrigerant charge responsibility

• Single-point responsibility and interface management
• Civil, electrical and mechanical scope boundaries
• Programme, milestones and liquidated damages
• Commissioning and handover documentation

• Local licences, certifications and insurance
• Site supervision and quality control
• Panel and pipework workmanship references
• Post-installation service arrangements

• Experience with the specific refrigerant at similar capacity
• Safety design, detection and machinery-room compliance
• Operator training and documentation
• Regional service capability for the technology

• Performance under frozen conditions
• Throughput guarantees and availability targets
• WMS integration and data interfaces
• Maintenance model and spare-part strategy

• Heat load and duty calculations with assumptions
• Equipment schedules and datasheets
• Single-line electrical diagram and connected load
• Layout drawings and panel specification
• Energy estimate with stated operating conditions
• Commissioning plan, O&M manuals, spare-parts list
• Reference list with capacity and temperature

Design ambient, evaporating and condensing temperatures, duty margin, airflow, defrost method, insulation values and control strategy. These, not brand names, determine whether the plant performs.

Ask for annual energy at stated conditions. Compare on the same tariff and operating profile, then check against the OPEX estimator.

Refrigerant affects safety design, permitting, service network and long-term regulatory exposure — it is a strategic, not cosmetic, decision.

Confirm who is responsible for safety studies, pressure equipment compliance, ammonia regulations, fire strategy and authority approvals.

Availability of critical spares, lead times and local technicians frequently matters more than a small efficiency difference.

A supplier without regional presence must present a credible service arrangement, otherwise downtime risk is transferred to the owner.

Ask for installations at comparable temperature, capacity and climate, and where possible speak to those operators.

ColdMatch prepares a single scope for all suppliers, collects responses against it, flags exclusions and inconsistent assumptions and presents a like-for-like comparison. The buyer contracts directly with the supplier they choose.

• One written scope issued to every supplier
• Design conditions fixed and identical
• Exclusions listed explicitly by each supplier
• Energy stated at the same operating profile
• Service and spares terms quoted, not assumed

Indicative planning tools only — not engineering design, refrigeration design or financial advice. Final numbers require supplier, engineer, refrigeration specialist and local regulatory review.
