Coolroom Fixture

Sterilization for Cold Storage

Bacteria and microorganisms grow wherever there is organic material.  In meat and other foodstuffs they proliferate.  In cool storage, the still multiple rapidly and every day that food is stored, the bacteria count increases. The result is the deterioration of the food, a breakdown of tissue, weight loss of the product and an increase of undesirable smells and taste and eventually, complete spoilage.  

Ultraviolet light at the germicidal wavelength of 253.7nm as produced by the CR-308 Coolroom Fixture has the remarkable ability to destroy all types of micro-organisms (including bacteria, mould & slime) thus preserving the quality of  foods in cold storage and greatly increasing their storage life.

Ozone is also produced using the option switch. With ozone produced, it can infiltrate shadowed areas with its own germicidal qualities, destroying unpleasant odours and creating sweet smelling, clean oxygen.  The CR-308 Coolroom fixture purifies air and controls bacteria to achieve a clean cold storage room.

Sterilizing Food Processing and Preparation Areas

• The CR-308 can be controlled by a timer.  When switched on while the room is unoccupied, bacteria and micro-organisms will be destroyed.  When switched off prior to re-entry by persons, the room is left clean and sterile. 
• Manual switching requires a notice of eye protection needed (glass spectacles) when working in close proximity to the CR-308 unit while on.

Protection of Foodstuffs


• Most foods that are subject to rapid deterioration due to the growth and activity of microorganisms can be protected with a CR-308 Coolroom Fixture.
• Fruit, vegetables, processed foods, fish, seafood, meat, etc all benefit.
• Care should be taken with fats and dairy products which may (if not sealed) be subject to a degree of rancidity if stored in an ozone environment. 
• CSIRO research has proved that meat storage life can be extended dramatically by the use of an ultraviolet light unit in a coolroom.
