Perrin creates SG-09 APU for Smeal Fire Apparatus

The SG-09 was designed to address the growing demand among fire departments for smarter supplemental power generation and climate control systems that meet more stringent engine idling laws, reduce fuel consumption and lower maintenance costs.


"As an ISO-certified designer and manufacturer of vehicle-based APU and HVAC systems, we specialize in assisting OEMs by engineering solutions to complex supplemental power and climate control challenges," Dan Koch, president and CEO of Perrin Manufacturing, said. "We are excited and honored to be invited to bring our expertise to bear on this initiative for Smeal."

The new Smeal APU comes in two models. The SG-09 Parallel System features a completely independent HVAC system with a separate evaporator core and fan installed in the crew area. The SG-09CR Integrated System utilizes the chassis evaporator, fan and air conditioning controls and allows the vehicle's air conditioning compressor to be mounted on the SG-09CR, freeing the chassis engine of the AC burden. With the augmentation supplied by the SG-09CR, fire companies can specify smaller engines and less expensive chassis, while achieving similar performance levels.
