The Patriot II is currently being redesigned and engineered by Canadian Extreme Climate Systems Ltd.
Currently featured on these pages is the Patriot I. Functionality for the Patriot II will remain the same as listed below.


  • Stainless Steel enclosure reduces corrosion and improves the appearance of the vehicle.
  • Easy access to filters from front cover and bottom air cleaner cover.
  • Draws cool outside air for engine combustion through a high performance filter with safety filter inside to protect your investment to the highest standards.
  • Draws air in away from air stream of truck to keep engine compartment much cleaner. Requires only enough room beside the unit to allow access to cover bolts.
  • Engine shut down protection for overheat and low oil pressure.
  • Entire inside of the covers insulated with special material designed to reduce the noise extremely.
  • Temperature controlled engine cooling fan exchanges air in APU only when required to reduce noise, power consumption and increases heat quickly for optimum efficiency of engine.
  • Provides more heat quicker than any other system on the market.
  • Multi chamber exhaust specially designed to reduce noise.
  • Automatic reset breakers for 110vac built into unit – no getting out to reset.
  • Newage double bearing generator with replaceable components.
  • Seltec TM16 compressor for improved volumetric efficiency for air conditioning.
