Cold Box Announces New Heating System For Cold Sensitive Cargo

Cold Box is pleased to announce a new alternative heating system to improve freeze protection for cold sensitive cargo that is now being implemented in the production and retrofit of new and existing Cold Box climate controlled containers.

Discovered by Director of Product Development, Tony Cook with the assistance of Director of Manufacturing, Richard Maze, the new heating system was originally developed for the flooring industry and uses advanced high tech carbon heating film to provide an underlying radiant heat source in the lower plenum chamber of the climate controlled boxes. The efficiency of the new alternative heating system far surpasses that of the previous cal-rod heater by providing a triple backup of heating capability for customer’s cold sensitive cargo. This is made possible because the heater is composed of three sheets of ultra-thin carbon film just .012 in. thick which amazingly provide 300W of heating. Empirical tests have shown that the loss of one sheet of film will have no affect on the boxes’ ability to maintain temperature in normal operation and the loss of two sheets will not impede the box from still being able to prevent freezing for cold sensitive cargo. In essence, the new heater is comprised of three independent heaters working together or separately should failures happen.

Another important feature for customer’s with cold sensitive cargo is the new heating system being Class 1, Division 2 compliant for hauling gaseous product. This is accomplished as the advanced carbon film’s radiant heat only reaches 65-71°C (150-160°F), well below the ignition point of a gas.

As new Cold Boxes are produced and existing containers are returned to the depots, all will be retrofitted with the new alternative heating system.
