Perrin’s lightweight APU

Dynasys SL APUPerrin’s 18-inch-wide Dynasys SL auxiliary power unit is an automotive-style HVAC system available with a multipurpose HVAC console that fits most day cab configurations and an under-bunk version that accommodates most traditional sleeper cabs. The lightweight system employs a belt-driven AC compressor to generate up to 24,000 Btu/hr of cooling power and heat dissipation from its diesel power plant to deliver up to 8,000 Btu/hr of heating strength.

The APU fits the frame rail mounting space and has a corrosion-resistant stainless-steel outer envelope, a heavy-duty zinc-plated frame with powder coating and an in-cab touchscreen user interface controller. The unit is designed with advanced noise reduction technology and powered by a two-cylinder diesel engine.
