Diesel-electric locomotives generate enormous quantities of waste heat — from the engine jacket water, turbocharger exhaust, and traction motor dynamic braking grids. The central air and cooling system dissipates this heat through a combination of radiator banks, cooling fans, water pumps, and blowers to maintain safe operating temperatures under all load conditions, including sustained full-power operation in high ambient temperatures.

Supco Canada supplies aftermarket cooling system components for EMD® and GE® locomotives — including 48-inch cooling fans, radiator assemblies, water pumps, lube pumps, dynamic brake grid fans, engine air filters, inertial air filters, electric cabinet filters, air discharge motors, auxiliary generator blowers, and the 5GDY gear unit that drives the cooling fan.

What We Supply

Cooling Fans
48-inch roof-mounted cooling fans and hub assemblies for engine radiator cooling — available as complete fan/motor assemblies or individual components.
Radiators & Water Pumps
Engine jacket water radiators and water pump assemblies — critical for maintaining cylinder liner and head temperatures within operating limits.
Air Filtration
Engine air filters, inertial air filters, and electric cabinet air filters — protecting both the engine and electronic equipment from airborne contaminants.
Blowers & Lube Pumps
Auxiliary generator blowers, dynamic brake grid fans, and engine lube pumps — maintaining correct oil flow and component cooling under load.
