Sara LBS Meets Food Industry Requirements with a Hygienically Designed High Speed Door

The Rapid Food Door is designed for fast opening and closing to ensure constant temperatures can be easily maintained in sensitive areas. The entire door, side frames, top roll and motor cover, and the bottom profile are made of V2A stainless steel with, compatible with standard washdown procedures and aggressive cleaning agents. Smooth surfaces ensure there is nowhere for dirt and debris to accumulate. The side frames are hinged to enable thorough cleaning and disinfecting of internal areas, and the side frames are open at the bottom so that cleaning fluids and water can completely run off, eliminating the possibility of dirt and debris being trapped inside. A gutter on the bottom profile prevents liquids from the curtain from dripping into the clean opening.
The door has a curtain of clear PVC with vertical reinforcement stripes. A wide range of RAL colours for the reinforcement stripes are available on request. An FDA-tested PVC curtain with white reinforcement stripes is also available.

The door is powered by a geared brake motor, which can be fitted on either the right or left side. For increased hygiene, the door can be equipped with a stainless steel motor and barrel cover, with the barrel cover hinged for cleaning purposes. The motor is controlled by an MCC Vector Control frequency converter, with the motor/drive combination delivering rapid opening and closing of the door. The frequency converter’s user interface provides simple, user-friendly controls, and a graphical display for status, diagnostic and troubleshooting messages.

As standard, the door is equipped with an electrical safety contact edge and a door line photocell to ensure user safety. Optionally, a pre-running safety photocell can be installed instead of the electrical contact edge. In the event of interruption or a power failure, the door can be opened manually using a crank handle. As an option, a counterbalance can be fitted to the door, such that the door can be opened automatically during a power failure by pulling the Bowden lever. The Bowden lever releases the brake, and the counterbalance system pulls the door up.

With a space-saving construction, hygienic design, reliable fast operation and an effective seal when closed, the Rapid Food Door meets all the requirements for access in food processing environments. It has been developed to be fully compliant with the hygiene legislation governing the food processing workplace, and with all European safety requirements for power operated doors.
