Doors open at 2m per second

The project was managed by a specialist construction company who facilitated the installation of three SST-L ECO doors. The project formed part of a new ambient and chill warehouse extension and features the Efaflex patented spiral design with door opening speeds of up to 2 metres per second.

The client had previously used a variety of fabric speed doors, but chose Efaflex to maintain critical temperature control between the ambient and chilled food areas. Darren Turrell, Efaflex general manager says: "We offer the first truly single door solution for deep freeze areas, to provide both the fastest operational speeds, coupled the best insulation for spiral doors; they are practically hermetically sealed.”

He adds: "It’s a delicate balancing act for chilled and frozen food processors; that of maintaining consistent temperatures and reducing the impact of ambient areas. Our energy-efficient doors are engineered to the highest quality and feature frames and laths to help substantially reduce energy costs, creating constant climate conditions in deep- freeze units.”

Contact surface heaters are employed throughout the whole door and integrated into the seals and contact bar resulting in a U value down to 0.74 W/m²K, and operational temperatures between plus and minus 30°C. The TK series features 100mm thermally insulated laths and can be matched to any RAL colour.

Designed for up to 200,000 operational cycles per year, Efaflex supplies doors to many chilled and frozen food producers, backed with a full after sales maintenance and service programme to match the client’s use and needs.
