Mining Machinery Air Conditioning and HVAC Repairs in Kathu

Working conditions around Kathu

Kathu is the centre of South Africa's iron ore mining region, with very large open-pit fleets, ultra-class haul trucks, drill rigs and extensive maintenance workshops. Extreme summer heat, low humidity and abrasive iron ore dust in a pit environment where condensers and cabin filtration are under continuous attack.

Diagnostic process

• Operator interview and fault confirmation with the machine running under load
• Visual inspection of condenser, belts, hoses, wiring and cabin filters
• High and low side pressure testing against the manufacturer's specification
• Electronic leak detection, dye tracing or nitrogen pressure testing where required
• Electrical fault finding on clutches, relays, pressure switches and control modules
• Written findings, parts list and repair recommendation before work proceeds

Repair approach

• Correct recovery of refrigerant before any component is opened
• Compressor, condenser, evaporator, drier, valve, blower and harness repairs or replacement
• System flushing and drier replacement after contamination or compressor failure
• Vacuum, leak hold test, charge by weight and oil balance to specification
• Function test across the full temperature range with cabin outlet readings recorded

Preventative maintenance recommendations

Scheduled condenser cleaning, cabin and pressurisation filter replacement, belt and clutch inspection, pressure checks and electrical inspection at fixed service intervals reduce the chance of unplanned cabin cooling failures during production hours.
