Drill Rigs HVAC for Open-Cast Mining Fleets
Epiroc PV-235/275, Sandvik D45/D75, Atlas Copco blasthole rigs
Static drilling positions where cuttings dust settles directly onto the machine. Static operation means no ram air across the condenser — every degree of cooling depends on fan performance and a clean core.
Dominant failure modes
Condenser fan motor failure with zero natural airflow to fall back on
Drill cuttings packing the condenser and pre-screens
Cab operator-station heat load from mast-side radiant gain
Electrical control faults from dust-bridged relays and connectors

A system that has lost even 15% of its condenser capacity cannot bridge a 20°C gap. That is why fouled cores and marginal charge levels present as complete cooling failure on a Lephalale bench, and why we verify every repair with a measured delta-T under load rather than a gauge reading at idle.
