The DNA Coldspeed 1 is a self-repairing roll up door with a special sandwich curtain. It is specially designed for refrigeration area. Thanks to the high degree of thermal insulation in the 18mm thick curtain it is ideal to divide environments with positive and negative temperatures. The frame structure is equipped with heating cables placed in the sliding self-repair system and in connecting pieces.


This makes the Coldspeed 1 ideal for refrigerated areas where it is important to separate environments with a positive or negative temperature. This avoids condensation and ice build-up which can be dangerous for workers and can impede the operation of the door itself.


The Coldspeed 1 can be installed in both positive and negative temperatures. Thanks to the non-rigid curtains and the sliding self-repair system if a collision occurs the curtain leaves the guide to prevent damage. Once the door is in the open position it will begin to close and automatically reinsert itself.

Dynamicroll Devices

All doors are supplied with a crank handle as standard for use in case of a power cut. A stop is activated for safety purposes, so the door cannot be used while the handle is in place. A Hand chain can be supplied if requested. A UPS Battery can also be fitted to maintain power during a power cut. This should be enough to activate the door a couple of times if needed.

Think safe

Installation is quick and easy as the Motor, Control Panel and Encoder cables are pre-wired into plugs for fast and simple connection on site.

Time saving

The Coldspeed 1 has a patented self-repair sliding system with a side zipping system that creates tightness across the curtain and improves wind resistance. If a collision occurs the curtain leaves the guide to prevent damage. Once the door is in the open position it will begin to close and automatically reinsert itself. This saves time as no intervention is needed.
