Imok 2:  I am looking at a variety of rooms for holding food items in transit between processing, ranging from 4m x 2m x 2.25m typical to like 4m x 4.2m x 2.25m. The only common denominator in the dimensions is the height of 2.25m. Its the modular coldroom type with polyurtethane foam insulation. Temperature range +30 deg centigrade to -12 deg centigrade
