For temperatures not lower than 20°C

Automatically operated sliding door model BTSA 120/400V (door thickness 120 mm) can be used in refrigerated rooms where the temperature is not below -20°C.

They are equipped with perimeter and base heating elements to prevent ice formation and allow the seals to be effective at all times. The (high-power) heating elements are not inserted inside the seals, but are built into the door structure and the omega floor edge (to increase heat transmission).

Automatic sliding doors are used in environments where there is considerable movement of people and goods with frequent door opening. The technical specifications of the door and the automation are designed to minimise wear and tear and therefore maintenance (except for routine maintenance by the customer).

Various functions and visual checks are already built into the control unit to check the operational status of each component. It is also possible to integrate (even at a later date) multiple devices that can facilitate use and management of the door (e.g. radio control, safety or opening photocells, radar, pull cord, etc).
This allows the automatic door’s operation to be customised according to the customer’s needs.
The BTSA 120/400V model is equipped with an internal and external lever handle to facilitate opening (on all doors).

At the customer’s request, an IP 65 automation system can be installed inside the room, even in a negative environment.

The doors are available in zinc-plasticised sheet metal (various colours), in stainless steel with ScotchBrite finish or in fibreglass.

Optional fittings are available on request, depending on the environment in which the door will be used and the customer’s needs.
• PVC frame cladding with stainless steel and 20/10 stainless steel;
• only one stainless steel or plastic-coated zinc sheet panel in one of the available colours;
• supply of stainless steel connecting sheets.

If the door is installed under special environmental conditions and if there is a raised panel inside the room (forming a step between the door and the outside of the room), it is possible to create a raised threshold of the desired thickness, which can be used by the customer to install a ramp to access the room.
