6. Envelope, insulation & doors
- Insulated panels: PU/PIR, density ≥ 40 kg/m³, class B fire rating minimum (EN 13501 / FM 4880 where applicable). - Panel U-values: chilled ≤ 0.30 W/m²K; frozen ≤ 0.20 W/m²K; deep-frozen ≤ 0.16 W/m²K. - Vapor barriers continuous; floor heating cable grids under frozen rooms with monitoring. - Cold-store doors: motorized bi-parting or hi-speed roll-up, heated frames, safety edge, opening cycle rating ≥ 200,000. - Dock equipment: insulated levellers, inflatable shelters, air-curtains at every reefer bay.
7. Controls, BMS & monitoring
- Refrigeration controls: open-protocol (Modbus TCP / BACnet IP) — no proprietary lock-in. - BMS shall log temperature at ≤ 5-min intervals for a minimum of 24 months with tamper-proof audit trail. - Remote alarm to on-call engineer via SMS + email; escalation matrix documented. - Trending, KPI dashboard and export to CSV / API for buyer's ERP / WMS.
8. Electrical, power & backup
- **Primary supply:** Utility grid with diesel/gas backup genset (N+1) - Backup power shall carry 100% of refrigeration load, 100% of controls, 50% of lighting, and dock equipment. - Auto-transfer time ≤ 10 s; fuel or battery autonomy ≥ 12 h at full load. - Power quality: THDi ≤ 5%; power factor ≥ 0.95 at PCC. - All motors ≥ IE3 (IEC 60034-30-1); VFDs on all compressors and evaporator fans.
9. Testing, commissioning & handover
- **FAT (Factory Acceptance Test):** buyer or nominated inspector to witness; pass/fail criteria pre-agreed. - **SAT (Site Acceptance Test):** performance run over ≥ 72 h at design load; deviations logged and re-tested. - **Pull-down test:** empty and loaded pull-down curves recorded. - **Temperature mapping (empty + loaded):** minimum 12 data-loggers per room, 48 h each phase. - Independent commissioning agent recommended and priced as an option in the bid.
10. Documentation deliverables
Supplier shall deliver, prior to final payment, hard copy + editable soft copy of: - Heat-load calculation, refrigerant charge calculation, pipe-sizing report - P&ID, single-line electrical, control philosophy, cause-and-effect matrix - As-built drawings (architectural, structural, MEP, refrigeration) - Equipment datasheets, serial numbers, refrigerant certificates - O&M manuals in Nigeria local language + English - Training records (minimum 3 buyer staff, 3 days on-site) - Spare parts list with 24-month critical spares priced separately
11. Warranty, spares & lifecycle
- **Warranty period:** 2 year(s) from SAT sign-off, parts and labour, response ≤ 24 h. - **Critical spares stocked:** 2 year(s) of consumables and wear items priced at bid stage. - **Service level agreement (SLA):** MTBF, MTTR and uptime targets shall be quoted for optional 5-year extended service. - **End-of-life:** supplier shall quote refrigerant recovery and equipment take-back option (F-Gas / Kigali compliant).
12. Bid evaluation criteria
Bids shall be evaluated on the following weighted matrix — buyer will not award on lowest capex alone: | Criterion | Weight | | --- | ---: | | Technical compliance (heat load, redundancy, safety) | 30% | | Lifecycle cost (10-year TCO — capex + energy + service) | 25% | | Delivery schedule + local execution capability | 15% | | Warranty, SLA and spares programme | 10% | | References — 3 similar projects in the last 5 years | 10% | | Financing / payment terms flexibility | 10% | Non-conformances must be listed on a dedicated deviation sheet with technical and commercial impact.

Anexar à RFQ Esta especificação é um modelo inicial construído a partir de boas práticas de engenharia independentes (ASHRAE, EN 378, IIAR-2, GDP). Confirme as condições finais de projeto e os requisitos de segurança com um engenheiro de refrigeração qualificado antes de enviar aos fornecedores.
Construtor de especificação técnica: perguntas de compradores
- O que é uma especificação técnica pronta para RFQ?
- Um documento que lista, sala a sala, as classes de temperatura, a redundância da refrigeração, normas e códigos, controles, backup elétrico e testes de comissionamento com detalhe suficiente para que todos os fornecedores cotem o mesmo escopo — permitindo comparar propostas de forma justa.
- A ColdMatch projeta o sistema para mim?
- Não. Esta ferramenta cria um modelo estruturado inicial com base em boas práticas de engenharia independentes. Um engenheiro de refrigeração qualificado deve confirmar as condições finais de projeto, os cálculos de carga térmica e os requisitos de segurança antes de enviar a especificação aos fornecedores.
- Posso anexar isso diretamente a uma RFQ?
- Sim. Use "Anexar à RFQ" para levar os detalhes do seu projeto, salas e normas diretamente para o Construtor de RFQ, onde o mesmo escopo é enviado a vários fornecedores adequados.
- O resultado é neutro em relação a fornecedores?
- Sim. A especificação é independente de qualquer fabricante ou marca de refrigerante específica — ela lista a família de refrigerante, a redundância e as normas necessárias, deixando a seleção de equipamentos em aberto para as propostas dos fornecedores.
