LHD Air Conditioning — Performance Testing in Kroondal
This page covers lhd air conditioning in Kroondal, chrome and platinum within the Rustenburg mining belt. Measured verification of pressures, temperature split and airflow so system condition is a recorded number, not an opinion. Chrome handling produces a dense, abrasive dust that packs condenser fins far faster than typical mine dust, so condenser cleaning and filter regimes here are deliberately more frequent.
LHDs in the Rustenburg belt
LHD HVAC repairs arranged through Rustenburg should use the planned surface maintenance window to inspect rock-contact damage and wet electrical connections. A cabin that cools while dry in the workshop may still lose airflow through saturated filters underground. Checking drainage, guarding and sealing alongside the refrigerant circuit makes the release test more relevant to the next tramming shift.
Typical specification
14 000 – 22 000 BTU/h typical cabin duty
Underground ambient conditions combine heat with high humidity, so a functioning system controls both temperature and moisture. Operators working long tramming cycles in that environment are directly affected when cooling degrades, and dust control depends on keeping the cabin closed.
Common problems in this application
- Impact and rock damage to condensers, guards and exposed hoses
- Continuous water ingress and drain blockage in humid workings
- Refrigerant loss at vibration-fatigued fittings
- Corrosion of coils and mountings from washdown and mine water

FAQs
Yes. Kroondal falls within our working area around Rustenburg, and attendance is arranged with your site so access, permits and induction are in place beforehand. Kroondal, immediately south-east of Rustenburg, combines platinum operations with established chrome mining and processing.
