Cold storage and food industrial products

Our doors designed and constructed to suit the demands of cold storage and food industry are manufactured with polyurethane foam technology of a high heat insulating level, with a thickness of 40-160 mm depending on the door types, from stainless steel or polyester coated plates. In each case the doors come with stainless steel frame structure, and in cold storage temperature range the doors are fitted with a threshold sunk below the floor level and with a built-in heating. Smaller doors and doors used in normal temperature range are fitted with a frame closing the panel opening, which is extremely simple to put in and is also suitable for covering the panel edge, so there is no need for a counter-frame or for subsequent panel closing when putting in the door.

For use in cold storage rooms we recommend manually operated or automatic single or double normal-operating, sliding or swing doors, and for use in large food industrial rooms where no heat insulation is required we recommend 40 mm thick sliding, doors, normal-operating doors without insulating rubber, and 3 different types of swing doors. We offer ordinary safety locks or safety locks with emergency handle inside, doors with inspection window, with frame-mounted upper guide-runner, with external mechanical shock-protection and with air-pressure flush-out valve.

Air curtains

We recommend the use of air curtains to reduce heat loss as much as possible, for doors with dense person but first of all forklift truck traffic, where a PVC curtain could get easily ruined by fork-lift trucks. The performance of the air-curtain is determined depending on the size of the door, in a single- or double-motor version, its operation can be synchronised with the opening of the door by installing a limit switch. The external cover of the structure is stainless steel.

Hospital and clean room products

We recommend doors conforming to clean area prescriptions for hospital and pharmaceutical industry uses, where nothing protrudes from or is depressed into the plane of the door wing (e.g. the inspection window and its frame, bottom guide rail) due to this there is not bacteria-collection or dust trap surface. The doors are 50-60 mm thick, their material is polished non-corroding or special polyester coated galvanised plate. The frame structure is in all cases made of a stainless steel material, in customs sizes conforming to the various wall structures or plasterboard structures.

We recommend Swedish BESAM electric door openers for the operation of automatic hospital doors, these are top quality, reliable products. If required we can provide various levels of radiation protection in the doors, in the built-in inspection window and in the frame.
