Preparing a Mining Fleet for Rustenburg Summer

Cooling systems that are marginal in winter fail in summer. A machine slightly low on refrigerant, or with a half-blocked condenser, will still blow cool air at 22°C ambient and will not cope at 38°C.

The practical answer is a pre-summer sweep: measure vent temperature and airflow on every machine, clean condensers properly, replace filters on measured airflow rather than hours, and locate leaks instead of topping up. Machines that fail the measured checks get planned into a shutdown before the peak arrives.
