Mobile Plant HVAC for Open-Cast Mining Fleets
Crushers, screens, mobile compressors, dozer-push units, drill support plant
Semi-mobile plant operating for long campaigns in one pit position. Operator cabins and control kiosks on mobile plant are frequently overlooked in fleet maintenance schedules until they fail outright.
Dominant failure modes
Cabin units left off maintenance schedules entirely
Vibration-induced refrigerant loss at plant frame joints
Control kiosk over-temperature causing electronics faults
Power supply instability damaging compressors and fans

Required cab temp
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.
