Objectives

The primary objective is to procure, deliver, install, and commission one new vaccine refrigerator/freezer unit for the Ilembe Health District Office. The contract aims to secure reliable cold-chain storage for vaccines in strict compliance with World Health Organization guidelines, while ensuring full operational readiness through on-site commissioning, staff training, and long-term technical support.

Scope

The scope covers the complete supply and delivery of a single unit, including transportation, physical installation, functional commissioning, and formal acceptance testing. It encompasses incidental services such as the provision of a starter pack of essential accessories, comprehensive user and service documentation, calibration software, and mandatory training for departmental health technology personnel. The contract includes a minimum 24-month warranty followed by a fully costed three-year preventive maintenance agreement. Evaluation follows a three-stage process: administrative compliance, technical specification adherence, and a price-based assessment utilizing an 80/20 preference point system, which allocates 20 points specifically to promote South African-owned enterprises.

Technical Requirements

• Cold Chain Compliance: The unit must be listed on the WHO recommended list for vaccine refrigerators and utilize CFC-free R134a refrigerant.
• Temperature & Capacity: Refrigerator compartment must maintain +2°C to +8°C with a minimum capacity of 200 litres. The freezer compartment must reach -12°C to -24°C with a minimum capacity of 40 litres.
• Power Failure Resilience (Hold-over Time): The unit must sustain safe temperatures for at least 48 hours during grid failure. This is achieved through steel tanks filled with a glycol/water mixture embedded in the cabinet walls, which freeze at -10°C to act as a thermal reservoir.
• Independent Cooling Systems: Two separate condensing units must serve the refrigerator and freezer compartments independently to prevent cross-compartment temperature failure.
• Controls & Alarms: Equipped with a digital two-stage electronic thermostat, internal air circulation fan, and audible/visual alarms for temperatures outside the +2°C to +8°C range. An anti-freezing mechanism automatically activates an internal heating light when temperatures approach freezing.
• Construction & Safety Standards: Roto-moulded polyethylene casing and interlining, 100mm foamed polyurethane insulation, hospital-grade 3-metre SANS colour-coded mains cable, and compliance with IEC 60601-1, IEC 60601-1-2, CE certification, and SANS 0142 wiring standards.
• Documentation & Software: Provision of two sets each of user and original service manuals (including fault-finding guides, circuit diagrams, and PCB layouts), plus all necessary calibration and maintenance software at no extra cost.
• Warranty & Maintenance: Minimum 24-month warranty covering all labour, spares, travel, and radiation control board testing. Downtime extends the warranty period day-for-day. A fully costed three-year preventive maintenance agreement must be submitted upon warranty expiry.

Skills Requirements

Bidders must demonstrate access to a well-established local service facility in KwaZulu-Natal staffed by Original Equipment Manufacturer (OEM)-trained technicians. These personnel must possess advanced diagnostic and repair capabilities, including Printed Circuit Board (PCB) level troubleshooting, which involves diagnosing and repairing faults at the individual electronic component level rather than replacing entire modules. The supplier is required to deliver comprehensive hands-on training to departmental health technology technicians, issuing a Certificate of Competency upon completion. Additionally, bidders must guarantee a 24-hour response time for malfunctions, maintain a local spare parts inventory guaranteed for ten years, and supply temporary loan units if equipment requires off-site repairs. All service agreements, training programs, and incidentals must be fully funded by the bidder.
