The possibilities are endless to utilize the efficient thermal liner fluid warmer design. Simple in-line installation means ultimate flexibility wherever engine coolant is available to recycle the valuable heat that would otherwise be lost. Arctic Fox leads the industry in diesel fuel warming?thousands of units have covered millions of miles in over-the-road equipment. Warmed diesel fuel does not gel in cold temperatures and, in areas where low grade fuel is prevalent, heating raises the efficiency while lowering emissions. Large off-highway equipment with 2-5 GPM / 8-19 LPM fuel flow can easily be handled with one of these three Thermal Liner fluid warmer sizes. In series, these units serve the largest diesel fuel consumers like locomotives and huge haul trucks. Easy installation in the fuel line (1/2? NPT or 1? NPT fittings), and a reasonable cost guarantees warm fuel for trouble free operation in cold climates.
