Coldsaver Door
Coolroom, chiller and freezer applications require a specialized door, and over the years, DMF have provided high speed rapid roll doors with polyskin type panels. DMF now have a new flexible high speed door product that can withstand this harsh condition. Loss of refrigerated air can be very expensive, and so this new type of rapid roll door comes with a 15mm thick insulated panel design.
Based on a similar design to our Series RL3000 door, the Series Coldsaver door will offer a greater level of insulation to temperature AND noise, and is suitable for opening sizes up to 4500H x 4500W
