DMF International has introduced the Insulated Roller Shutter door.
The Insulated Roller Shutter door is essentially an automated roller shutter type door but using an insulated slat (or lath), so as to provide a higher level of insulation to what a standard metal roller shutter door of high speed PVC door can provide.
With either a foamed PU or special option of PIR filling, the slats can be up to 20mm thick, and with an operational speed of about 200mm/sec, this is a good alternative to the sliding doors for coolrooms.
Activation can be by pushbuttons, remote control, or other forms, and the Insulated Roller Shutter door is driven by a tubular motor meaning that side room requirements are minimised.
The Insulated Roller Shutter door is not a high speed door but if this feature is necessary DMF International can help.
