The "Drikold' VanCooler--an efficient, but cheap, thermostatically controlled refrigeration system for retail delivery vans carrying perishable goods—is now being marketed by ICI Agricultural Division.
The unit costs £60 and is designed to be operated with Drikold. ICI's solid carbon dioxide. Unladen, the unit, made from galvanized steel, weighs 621b, is 4ft 6in. high and 1ft 91n. deep. With a full charge of 1201b of crushed Drikold, the maximum cooling capacity of the unit is 32,000 Btu. The VanCooler is easily removed from a vehicle for cleaning or when not required. It is designed especially for use in vans operating at temperatures of 35-50 deg F, where refrigeration is required during the summer months only and where a large capital outlay is not justified.
The Drikold VanCooler is normally positioned free-standing inside the van at the front of the insulated compartment, against the bulkhead. It operates by means of a thermostatically controlled fan which passes air through a bed of crushed Drikold, where it is cooled, and then circulated inside the van.
The doors of a retail van may be opened as many as 60 times a day, each time allowing the cool air inside the van to escape and warm air to enter from the outside. The VanCooler counteracts this temperature rise by operating immediately the doors are closed to bring the temperature down to the level set by the customer on the thermostat, which then cuts out the fan.
