TEMPERATURE CONTROL Klinge’s redundant refrigerated containers can help shippers meet requirements under the IMDG Code for the transport of certain dangerous goods

The International Maritime Organisation (IMO), in the International Maritime Dangerous Goods (IMDG) Code, has identified a number of substances as requiring refrigeration during transport. Refrigerated units must have a redundant system, with back-up refrigeration and power supply. Included among the list of substances are organic peroxides of Division 5.2 and self-reactive substances of Division 4.1.

Without proper temperature control, uncontrolled decomposition of organic peroxides and self-reactive substances can occur. In fact, self-reactive substances are exothermic and can explode if not maintained at the correct temperature. As such, says Jason Flynn, sales manager at Klinge Corp, “It is no surprise that many of the largest shipping lines in the world will refuse this type of hazardous cargo if it does not have redundant refrigeration and an integral generator set for back-up power supply.”

“Over the last few months we have seen increasing demand by chemical and pharmaceutical companies for redundant refrigeration units to transport organic peroxides and self-reactive substances as required by the IMDG Code,” Flynn continues. “Companies are realising more and more that when it comes to safely transporting and storing chemicals, nothing is as important as the control of temperature.”

Klinge Corp supplies redundant refrigerated containers equipped with a primary and back-up refrigeration unit. It automatically switches to the back-up in the event of a loss of performance or system failure. Similarly, an integral diesel generator can be installed, which is capable of powering the refrigeration unit if there is a loss of external power or during transport by truck.

Klinge’s product portfolio also includes explosion-proof refrigerated containers, refrigerated tank containers and ultra-low temperature transport units. It has recently extended its expertise through the acquisition of Danish company Norfrig Equipment, which specialises in ultra-low temperature and quick-thaw solutions.
