Solutions within APU

APU

Fully Integrated Solutions

A fully integrated Auxiliary Power Unit (APU) is a critical component in next-generation ICE vehicle platforms, designed to support onboard power generation, climate control and thermal management without reliance on the vehicle’s primary engine. Calatherm’s fully integrated APU solutions are engineered within the existing vehicle architecture and work either independently or in co-generation mode. Often sharing common cooling and electrical circuits, optimise energy efficiency and protecting system reliability throughout the vehicle lifecycle.

APU

Auxiliary Power

Auxiliary Power (APU) is designed for when space constraints within the vehicle prohibits the use of an integrated solution, an auxiliary power can often provide a viable alternative, particularly when upgrading or enhancing an existing platform.
