Minus Forty Technologies introduces a cold plate storage unit that bolts directly to truck floors with no requirement to connect to a vehicle's electrical system. Powered by a self-contained system, the storage unit plugs directly into a 120 volt receptacle at night and left to recharge. The storage unit pulls down to -25 degrees F in an 8 hour span and holds that temperature for 14 hours the next day while the truck is on its deliveries with no power requirement. With no need for rebuilding or redesigning the delivery truck box, the storage unit is a cost effective way of providing a 8 cubic feet of space for frozen foods and ice cream.
