Redundant Refrigeration Units
Klinge Corporation’s Redundant Refrigerated Containers have two (primary and back-up refrigeration units. The refrigeration unit automatically switches to its back-up in the case of a loss of performance or system failure to provide the ultimate peace of mind when shipping hazardous cargo or valuable cargo.
Klinge's line of Redundant Refrigerated Containers are used to transport hazardous chemicals, resins, adhesives, pharmaceuticals, ammunition and other goods requiring extra protection. Klinge Corporation has been providing this model to major chemical and pharmaceutical companies around the world for nearly 30 years.

protection for hazardous of temperature-sensitive goods. Read more.
REDUNDANT REFRIGERATION AND THE IMO
As overheating or a spark could have catastrophic consequences, transportation of chemicals and other hazardous goods poses a major risk to shipping vessels, oil rigs, and manufacturing facilities where fire is a major concern and gas is present. As such, the International Maritime Organization (IMO), has required that International Maritime Dangerous Goods (IMDG) Classes 4.1 and 5.2 must be transported in:
"Dual mechanical refrigeration systems, provided that:
» the two systems are independent of one another;
» each system alone is capable of maintaining adequate temperature
control;
» for substances with a flashpoint lower than the sum of the emergency
temperature plus 5°C, explosion-proof electrical fittings are used
within the coolant compartment to prevent ignition of flammable vapors
from the substances."

IMO & IMDG CODE - BACKGROUND
The International Maritime Organization (IMO) was established in 1948
and was originally called the Inter-Governmental Maritime Consultative
Organization, or IMCO. The IMO was formed as a specialized agency of the
United Nations to develop international regulations, adhered to by all
nations, to ensure safety at sea and environmental protection.
The IMO was first tasked with adopting a new version of the
International Convention for the Safety of Life at Sea (SOLAS), an
international maritime safety treaty. The 1960 International Convention
was a significant step forward in the updating international shipping
regulations and is still the most important treaty addressing maritime
safety. Development of an international code for dangerous goods
transport by sea was among the items contained in the 1960 International
Convention for the Safety of Life at Sea (SOLAS). The International
Maritime Dangerous Goods (IMDG) Code includes guidelines on items such
as packing, container traffic and stowage, and segregation of
incompatible substances.
The IMDG Code was adopted in 1965. Amendments to the Code can be made by
the IMO's working group, the Maritime Safety Committee (MSC). Requests
for amendments may be made by member nations or in response to changes
to the UN Recommendations of the Transport of Dangerous Goods.
Amendments based on changes to the UN Recommendations are made every two
years.
IMDG CODE CLASSES
Dangerous Goods are broken into different classes and are further
subdivided into divisions. The classification can be made by the
shipper/consignor or the appropriate competent authority as specified in
the Code.
Class 1: Explosives
Division 1.1: substances and articles which have a mass explosion hazard
Division 1.2: substances and articles which have a projection hazard but
not a mass explosion hazard
Division 1.3: substances and articles which have a fire hazard and
either a minor blast hazard or a minor projection hazard or both, but
not a mass explosion hazard
Division 1.4: substances and articles which present no significant
hazard
Division 1.5: very insensitive substances which have a mass explosion
hazard
Division 1.6: extremely insensitive articles which do not have a mass
explosion hazard
Class 2: Gases
Class 2.1: flammable gases
Class 2.2: non-flammable, non-toxic gases
Class 2.3: toxic gases
Class 3: Flammable liquids
Class 4: Flammable solids; substances liable to spontaneous combustion;
substances which, in contact with water, emit flammable gases
Class 4.1: flammable solids, self-reactive substances and desensitized
explosives
Class 4.2: substances liable to spontaneous combustion
Class 4.3: substances which, in contact with water, emit flammable gases
Class 5: Oxidizing substances and organic peroxides
Class 5.1: oxidizing substances
Class 5.2: organic peroxides
Class 6: Toxic and infectious substances
Class 6.1: toxic substances
Class 6.2: infectious substances
Class 7: Radioactive material
Class 8: Corrosive substances

Class 9: Miscellaneous dangerous substances and articles
