Objectives

To procure, deliver, install, and commission two new medical-grade vaccine refrigerators for secure medication storage at Mandlakazi Clinic. The procurement aims to ensure uninterrupted cold chain integrity, regulatory compliance, and long-term operational reliability through comprehensive technical support and warranty coverage.

Scope

The contract is a one-off supply covering the delivery, installation, testing, and commissioning of two Minus 40 vaccine refrigerators. The scope extends to full handover training for clinical and technical staff, provision of all essential manuals, calibration software, and starter accessories. The successful bidder must provide a minimum 24-month warranty from commissioning and submit a fully costed three-year preventive maintenance agreement upon warranty expiry. All pricing must be firm, inclusive of VAT, transport, installation, and training, with quotation validity set at 90 days.

Technical Requirements

• Performance & Temperature: Refrigerator compartment must maintain +2°C to +8°C; dedicated freezer compartment must operate between -12°C and -24°C.
• Capacity & Dimensions: Minimum 200-litre fridge capacity and 40-litre freezer capacity. Approximate dimensions: 1700mm (H) × 700mm (W) × 650mm (D).
• Cold Chain Integrity: CFC-free R134a refrigerant, 100mm polyurethane insulation, and integrated glycol/water ice banks to guarantee a minimum 48-hour holdover time during power failures.
• System Design: Two independent condensing units (one per compartment), electronic digital thermostat with dual-stage control, internal air-circulation fan, and audible/visual alarms for temperature deviations outside the 2°C–8°C range.
• Safety & Compliance: CE certification, IEC 60601-1 and IEC 60601-1-2 electrical safety standards, SANS wiring code compliance, and hospital-grade 3-metre power cables with built-in voltage stabiliser.
• Documentation & Accessories: Complete user and service manuals (including circuit diagrams, PCB layouts, and fault-finding guides), calibration software, and a starter pack for immediate operation.
• After-Sales Support: Spare parts availability guaranteed for 10 years. A loan replacement unit must be provided if the primary unit is removed for repairs. Local service facility in KwaZulu-Natal required, with technician response within 24 hours.

Skills Requirements

• Bidders must demonstrate a permanent, well-established service and repair facility within KwaZulu-Natal, subject to potential inspection.
• Technical personnel must be original equipment manufacturer (OEM)-certified to perform diagnostics, calibration, and repairs down to the printed circuit board (PCB) level.
• Suppliers must possess the instructional capability to deliver structured training to departmental technicians and end-users, covering installation, routine maintenance, fault resolution, and safe clinical operation.
• Administrative and procurement compliance skills are mandatory, including accurate completion of all statutory returnable documents, Central Supplier Database (CSD) registration, SARS tax clearance validation, and B-BBEE status documentation to qualify for preferential scoring.

Explanation of Unusual or Complicated Terms

• Minus 40 Fridge: A specialised dual-compartment medical refrigerator designed for vaccine preservation. It features a primary cooling zone for standard vaccines (+2°C to +8°C) and a secondary freezer zone (-12°C to -24°C) primarily used to freeze thermal buffers/ice packs.
• Holdover Time: The duration a refrigeration unit can sustain its internal temperature range without grid power. Achieved through high-density insulation and pre-frozen glycol packs, this tender mandates a minimum of 48 hours to protect sensitive medications during load-shedding or outages.
• PCB-Level Training: Advanced technical instruction enabling staff to troubleshoot and repair faults at the component level on printed circuit boards, rather than relying solely on module replacements. This ensures deeper diagnostic capability and reduced downtime.
• WHO Recommended List: An internationally recognised registry of medical cold chain equipment that has undergone rigorous testing against World Health Organization performance, safety, and reliability benchmarks for global vaccine distribution programmes.
