Curtain

The DS800/DS850 High Speed Roller doors for freezer applications introduced by Eastern Doors in 2011 to enable us to offer a competitively priced door for low temperature applications.

Our door was selected from an overseas supplier who has developed the door over the past five years and whose market has been in Africa, South America, most of Europe and Scandinavia.

High maintenance costs, poor service and initial purchase prices being extremely high, along with high running costs have been reported from customer using competitor products in the UK.

Our criteria therefore was to find a lower cost door, which still offered quality engineering, could offer competitive pricing, minimal maintenance and would be less expensive to run than our competitors.

The door design came from the manufacturers normal doors used extensively worldwide for workshops, warehouses, supermarkets etc. A new fabric was developed specifically for low temperature applications. Heaters were strategically placed in the door construction so that frost build-up could not occur.

The knockout system was incorporated so that in the event of contact with the door, the curtain would be knocked out and could be reinserted, usually by the customers own engineers, using the minimum of tools.

Because of the moisture and humidity, stainless steel was chosen as the preferred construction material for the guides, barrel, endplates and canopy. This gives longer working life and requires no maintenance and it was thought the extra cost of the material was a worthwhile addition.

Their existing control system was tried and tested and so was incorporated into the design of the freezer door. This gives advice on any problems with the door, giving a digital display of where faults occur, so that repairing is simplified.

The DS800 is made in heavy stainless steel, providing, in addition to an easy-to-clean surface, max. strength to resist the impact and shocks which always occur on a busy day of work.
DS800 is available in max. size of 4 x 3.5 m.
DS850 for larger openings, available up to 4 x 5.5 m.

The idea behind this door is quite simple: It is about combining high speed with high insulating power.
The specially developed door leaf will provide effective insulation, and will keep the cold indoors.

We do, of course, believe fully in our products. Therefore, DS800 is protected by a number of patents, particularly on the door fabric and the special sealing system ensuring that cold and warm air will not meet and generate condensation. The door cloth is 43 mm thick, and has built-in stabilization. This offers extremely good insulation, as well as fine resistance to wind/pressure.
