The best solution for distributing ice cream in hot climates with high efficiency is electric cooling unit with cold eutectic plates. when the cooling system plug-in it will charge cold eutectic plates for 8~10hours and the temperature of eutectic plates will decrease to -33oc then it will plug-out and the ice cream truck will load ice creams and go for distributing. Depend on ambient and number of door opening, cold eutectic plates will keep inside temperature in permissible range. Using this cooling unit needs low investment in comparing with diesel units also with less maintenance costs.
