Oil Coolers

MineCool hydraulic oil coolers are vacuum-brazed bar and plate assemblies built for the thermal loads of heavy mobile mining equipment – excavators, dozers, wheel loaders, rock trucks and blast-hole drills operating in sustained high-ambient conditions.

Hydraulic oil temperature control is a direct constraint on machine availability. When oil runs hot, viscosity drops, pump and cylinder wear accelerates, seal life shortens, and the machine either derates or comes out of service. A degraded or blocked oil cooler is frequently the root cause, and on large mining assets the replacement lead time from OEM channels can extend well beyond the maintenance window.

Our oil cooler range covers hydraulic, transmission, steering, brake, axle, gearbox and compressor oil cooling duties, in direct-fit configurations for Caterpillar, Liebherr, Komatsu, Hitachi, Sandvik, Drill Tech and other heavy equipment platforms. Each unit is manufactured to fit the original mounting, port and core envelope, so replacement requires no fabrication or hose rework.

Hydraulic oil coolers by duty

Hydraulic oil coolers
The primary implement and swing circuit coolers on excavators, dozers and loaders. The highest-duty cooler on most machines and the most common failure point in high-ambient operation.

Transmission oil coolers
Powertrain cooling on rock trucks, dozers and scrapers, where sustained torque converter load generates continuous heat rejection.

Steering oil coolers
Dedicated circuit cooling on large wheel loaders and mining trucks with independent steering hydraulics.

Brake oil coolers
Retarder and wet-brake circuit cooling on haul trucks, where continuous downgrade braking is the dominant thermal load.

Axle and gearbox oil coolers
Final drive and swing gear cooling, typically on large excavators and rear-axle haul truck applications.

Compressor oil coolers
Blast-hole drill rig compressor circuits, where drilling duty cycles run near-continuous.
