Rock Drills Air Conditioning and HVAC Repairs

HVAC systems on rock drills

Cab cooling with heavy-duty pressurisation and multi-stage fresh-air filtration where an enclosed cab is fitted. Percussive operation creates severe vibration alongside intense fine dust, attacking both mountings and filtration.

Common faults we find on rock drills

• Vibration fatigue in pipes and fittings
• Filter saturation
• Fan and pressuriser failure
• Electrical connector damage

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

Regular fastener and fitting inspection combined with short filtration intervals.
