DMF International RL3000-Coldsaver high-speed insulated door

High-trafficked doorways to food processing areas, coolrooms and freezers require a specialised door that will not only operate quickly and efficiently, but provide a high level of insulation. Sydney-based company DMF International has supplied rapid roll doors with flexible PVC type panels for over 30 years and now has a more efficient solution for these applications — the RL3000-Coldsaver high-speed insulated door.

The flexible high-speed door can withstand the harsh conditions of bulk commercial coolrooms and freezers, and the door blade is constructed using a 15 mm-thick door panel using polyskin 900 gsm outer layer and pocketing high-density insulated cores.

Based on a similar design to its Series RL3000 door, the Coldsaver door can provide a greater level of insulation to temperature and noise. It is suitable for opening sizes up to about 20 m² and the doors are custom made to size and specification at its Sydney factory.

With operating speeds of over 1 m/s, and multiple safety sensors that prevent the door closing onto an object, the door is designed for hundreds of cycles a day.
