Assa Abloy Entrance Systems, a supplier of door solutions for people, places, and goods, has announced the unveiling of its automatic door for refrigerated trucks and trailers.

The Assa Abloy MD2000 automated reefer door opens fast, electronically senses the presence of workers and cargo passing through, and quickly closes once the passage is clear. The door will help streamline the food delivery process and ensure a constant temperature and humidity barrier for reefer interiors.

Until now, fleets and workers hauling refrigerated loads have had to contend with curtain-style barriers after opening exterior doors on refrigerated trucks and trailers. Often made of heavy, vertical strips of plastic, the curtains are porous at best, and create friction points for workers, significantly reducing the working dimensions of the opening. The strips are prone to swing, striking workers and dislodging cargo, making trips with heavy pallet jacks and hand trucks both difficult and frustrating.

The Assa Abloy MD2000 automated reefer door provides temperature control, food chain security, and significant fuel savings, while improving overall delivery efficiency. The door was specifically designed for refrigerator and freezer applications and has been tested and validated to operate at 0 degrees Fahrenheit.

The door can be easily installed on the face of a reefer’s interior wall by OEMs or retrofit on existing trailers within just a few hours, and Assa Abloy will send technicians to train qualified customers on proper installation and service techniques. The system comes with its own modular wiring harness kit, and all cables and connectors remain accessible at the point of use for easy service and maintenance.

A red LED light strip is mounted on both sides of the Assa Abloy MD2000 interior door frame and remains on when the door is closed to provide worker orientation in low-light conditions. The lights turn off when the door is open and begin flashing to signal when it is preparing to close.

The door’s closing cycles can even be custom-programmed between 0 and 90 seconds. Once closed, the secure barrier only opens for authorized personnel to prevent theft and potential adulteration.

The flexible door features a large clear window panel and a soft bottom edge, and retracts if it encounters any resistance, protecting delivery workers and eliminating potential damage to cargo. The door will break away in the event of incidental contact and can be placed back into operational position in moments.

The Assa Abloy MD2000 automated reefer door reduces interior temperature variability during frequent stops, keeping food safer. By significantly reducing the time it’s open, the door also prevents humidity from entering the refrigerated space, inhibiting condensation, vision-diminishing fog, and dangerous surface ice from forming on floors.

The Assa Abloy MD2000 automated reefer door ensures product control and integrity and will also positively impact the bottom line of fleets and owner-operators alike. Studies have shown by adding a high-performance door to the temperature-controlled food delivery process, fleets can enjoy fuel savings of up to 40% as well as lower maintenance costs, because the doors reduce the number of defrost cycles.

The Food Safety Modernization Act (FSMA) and 2002 Bioterrorism Act were signed into law to ensure the U.S. food supply is safe by shifting the focus from responding to contamination to preventing it. The Assa Abloy MD2000 automated reefer door addresses these regulatory requirements by providing a more reliable and consistent physical barrier between the products and the outside environment that better protects food quality and safety.
