Tender Summary: Minus 40 Fridge B300 Vaccine Refrigerator

Objectives

The primary objective is to procure one (1) new, high-specification vaccine refrigerator with integrated freezer capabilities for Harry Gwala Regional Hospital. The procurement ensures reliable, long-term storage of temperature-sensitive biological products in strict compliance with World Health Organization guidelines and provincial health department standards.

Scope

The successful bidder will manage the complete delivery and lifecycle support of the equipment, including:

• Supply, transport, installation, and commissioning of the unit at the designated hospital.
• Provision of comprehensive operational, maintenance, and technical documentation.
• Delivery of specialised training to hospital staff and Health Technology Services personnel.
• Provision of a minimum 24-month warranty covering all repairs, spare parts, labour, travel, and regulatory testing costs.
• Submission of a fully costed three-year preventive maintenance agreement commencing immediately after the warranty period.
• Maintenance of a permanent service facility in KwaZulu-Natal with guaranteed spare parts availability for ten years.

Technical Requirements

Bidders must offer a brand-new, latest-model unit that strictly complies with the following specifications:

• Capacity & Dimensions: Minimum 200-litre refrigerator compartment and 40-litre freezer compartment. Approximate dimensions: 1700mm (H) × 700mm (W) × 650mm (D).
• Temperature Control: Refrigerator must maintain +2°C to +8°C; freezer must operate between -12°C and -24°C. Both compartments require independent condensing units.
• Power Failure Resilience: Minimum 48-hour holdover time using internal glycol/water ice tanks embedded in the cabinet walls.
• Construction & Materials: CFC-free operation using R134a refrigerant. Outer and inner casings made of roto-moulded polyethylene. Insulation must be 100mm thick foamed polyurethane.
• Electronics & Safety: Digital two-stage thermostat with an anti-freeze heating element. Integrated alarms for temperature deviations. Compliant with IEC 60601-1, IEC 60601-1-2, CE certification, SANS 0142 wiring code, and the Occupational Health and Safety Act.
• Documentation & Software: Two sets of user and original service manuals (including schematics, PCB layouts, and calibration guides). All necessary maintenance software, security keys, passwords, and special tooling must be supplied at no additional cost.
• Accessories: Hospital-grade mains cable (minimum 3 metres), voltage stabiliser, starter pack of essential disposables, and castors for mobility.

Skills Requirements

While the tender does not mandate specific academic qualifications, it imposes strict competency and service infrastructure requirements:

• Technicians must be Original Equipment Manufacturer (OEM) trained to perform diagnostics, calibration, and repairs down to the Printed Circuit Board (PCB) level.
• Bidders must demonstrate a permanent, established service and repair facility within KwaZulu-Natal, subject to physical inspection by Health Technology Services.
• Suppliers must provide comprehensive training to institutional staff on calibration, maintenance, and repair, equivalent to factory-level training.
• Bidders must maintain adequate local spare parts inventory and guarantee technician response within 24 hours of malfunction reporting.

Explanation of Unusual or Complicated Terms

• Holdover Time: Refers to the duration the refrigerator can safely maintain vaccine temperatures during extended power outages, achieved through internal frozen glycol/water reservoirs rather than external batteries or generators.
• Anti-Freezing Light Mechanism: A secondary thermostat stage that activates an internal heating lamp when temperatures approach freezing, preventing vaccine damage without compromising overall cooling efficiency.
• PCB-Level Repair: Requires technicians to possess advanced electronic diagnostic skills capable of identifying and replacing faulty micro-components on circuit boards, rather than performing only superficial or mechanical servicing.
• Loan Set Provision: Mandates that the supplier provide a fully functional replacement unit at their own expense while the primary unit undergoes repairs, ensuring uninterrupted vaccine storage.
• Health Technology Services (HTS) Commissioning: A mandatory provincial health authority inspection and acceptance test that must be successfully passed before the warranty period begins and final payment is processed.
