POLAIR coldrooms feature different types of door blocks. 

The doors, similar to coldroom panels, have a three-layered sandwich structure and are canted with shockproof PVC profiles; they are complemented with МТН (Italy) accessories. Doors are 80 mm wide. 

Width of door block panels corresponds with wall panel width of either 80 mm or 100 mm. 

All necessary components are included in the standard set. 

For coldrooms with area light of 1200х1850 mm, roll-in (container) or sliding door can be provided. 

Low-temperature coldrooms feature a flat electric heating element along the door perimeter to prevent the door freezing-on (additional option to be purchased separately). 

Door blocks and doors can be purchased independently from coldrooms.
