Centramatic's APU's, air conditioning and heating systems are specifically designed for use in the trucking industry. Use of such systems for cab comfort and convenience comply with anti-idling laws and use roughly 75% less fuel as compared to idling the trucks primary engine. Increasing air quality legislation and local enforcement, coupled with soaring fuel costs have greatly increased APU demand.
