This compact new model is designed specifically to cool the cab of an 18 wheeler with the intention of creating an innovative way to keep cool while staying in compliance with the new No Idle Laws.  Please call for more details. The Double 8-12 (2-812) is similar to the KAR KOOL (see below) but self-contained! The Double 8 is named for its dual cooling fans (with two 8 inch diamater 12 volt fans) and can be installed with its own water reservoir. The unit has a  float  switch which controls an automatic fill system! Originally designed for 18-wheelers to provide cooling to drivers while parked to accommodate the new "NO IDLE LAW".  The new Double-8 can also be used in other applications, including pick-up trucks, RV’s, campers, small rooms or new additions and much much more!  Please contact us for more information of idle free cooling solutions with no gas mileage penalities.
