Hotstart - Model APU -Idle Reduction Heating System

By providing heat to the engine and lubrication oil, the HOTSTART APU allows locomotives to shut down in any location at any time while retaining the ability to restart immediately – even in the coldest conditions. Eliminating unnecessary idling and maintaining optimal start up temperatures for both critical engine components and oil reduces fuel consumption, oil consumption, emissions, noise pollution, engine wear, and wet-stacking.

Rail freight locomotives are susceptible to damage or delays due to freezing temperatures, requiring them to idle to maintain engine heat or be housed in climate-controlled locations. The HOTSTART APU frees locomotives from these limitations, allowing them to park and start up in any location at any time – maximizing their availability, prolonging their service intervals and allowing them to accommodate strict transport schedules.

Heat loss through wet cooling systems (wet radiator) during heating system operation may reduce or impair the heating system’s ability to maintain optimal heat levels for engine operation or engine start.
