Cold room is temperature controlled insulated project, its panel is made of PUF foam, also called Polyurethane sandwich panel, PUR Panel in which polyurethane foam is been sandwiched between the two outer galvanized steel covers. CFC-free insulated PU panel is commonly specification we supplied. B2 level fireproof can make sure the project during building and operation far away from fire accident.
· Cold Room Dimension: 12m*8m*4m use for vegetable after processing.
· Process workshop Dimension: 8mx5mx3m. for vegetable processing.
· Precool area, dimension 8mx3mx3m. for vegetable preparation before loading in Processing workshop.
· Cold Room Inside Temperature: 0℃.
· Precool area temperature: +15℃.
· Process workshop temperature: +12℃.
The vegetable Our customer collect from farm, +35 ℃, Same temperature with ambient temperature.
Need to put them into precool area to cool to +15℃ first, and then do necessary process and packed, transfer to cold room for long time store.

Before starting the assembly of the panels, make sure that the locking devices are at the stop position. To do so, turn the locking devices counter-clockwise, using a wrench, with force, until it stops moving any further.
Push panels together and turn wrench 1/4 turn clockwise. This will engage the male locking device “arm” over female locking device “pin”.
Keep turning the wrench for another _ of a turn until the wrench stops moving any further.If there are any problems during the operation of cam locks, turn the wrench counter-clockwise with force until it stops moving any further. This will put the locking device at its original position and you can try to assemble the panel again by moving the wrench in a clockwise direction.
