Double PVC curtains (airspace between 200 mm)
The DNA Products Coldspeed 2 is a self-repairing roll up door equipped with 2 curtains without any rigid elements. A 200mm divide between the curtains in the closed position creates and insulated air space.
This makes the Coldspeed 2 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 2 can be installed in both positive and negative temperatures and it's a guaranteed of safety for workers and means. 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.

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.
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.
