ith summer on the horizon thoughts turn to keeping cool during the sweltering months that lay ahead. Thinking also migrates to the various cooling systems for trucks on the market, their costs and efficiencies. Of note to many is the ongoing debate over preference between battery powered air conditioning systems and auxiliary power units (APUs). Battery powered systems are quiet and relatively maintenance free compared to APUs that require constant maintenance - oil changes, filters, etc. around every 500 hours. The maintenance issue is a problem for fleets because of the cost related to upkeep of APUs. Fuel used to operate an APU is less than running the truck to be sure, but is in excess of a battery operated system. Noise in APUs is a factor as well. The advantage of an APU, however, is that if an operator has to be somewhere for 2 or 3 days then an APU makes sense as they run for longer periods. Still, as battery technology improves running times are extended. And more recently companies are improving on battery life as well with the use THEME >> PAGE 4
