Isothermal and service doors

The PVC strip curtains are suitable for separating different working areas and they serve as flexible barriers next to isothermal doors, to reduce the thermal loss or the entry of hot air (to prevent condensation) during the daily operation of opening and closing.

They are made of:

  • Plastic support in dark grey color consisting of a profile to be fixed to the panel by self tapping screws and a plastic covering molded as part of the same support, to cover the structure and to give an aesthetical enhanced result, easy to clean and without sharp edges, (dowels available on demand).
  • PVC transparent strip curtains, dim. 200x2 mm with 50 mm of overlapping.

Flexible strip closures in transparent PVC are suitable for creating separate spaces and in particular, as flexible barriers, for use near refrigerator doors to limit thermal dispersion or infiltration of hot air (and the consequent condensation) during the opening and closing of these doors.

They consist of a sturdy load-bearing structure in AISI 304 stainless-steel profile sections and of transparent PVC strips with rapid rocking lock and release fitting in stainless steel.

The strips are available in 2 different versions:

  1. Mod. ST 200 x 2, consisting of transparent PVC strips measuring 200 x 2 mm with 50 mm overlap.
  2. Mod. ST 300 x 3, consisting of transparent PVC strips measuring 300 x 3 mm with 100 mm overlap.

The Transparent Flexible Doors of the CFD series are an effective barrier to the passage of air through isothermal doors in the event they remain open due to intensive traffic, whether pedestrian or trolleys. They offer maximum protection against heat loss, controlling energy consumption.

They are also a valid solution in case a dividing door with maximum visibility is required.

The CFD series doors are available in the single- or double-leaf versions, consisting of:

  1. A special stainless steel and aluminium gravity hinge with two-way rotation forms the load-bearing structure of the door. Due to its special design, it closes the door automatically.
  2. Transparent PVC mantle 3 mm thickness: Polar Type for operating at negative temperature from -20°C to 40°C

The absence of posts allows optimisation of the door opening, unlike the conventional "FLAP" doors. It is much more accessible compared to the traditional Strip Doors as it avoids the hassle of strips that fall against the operator, so passage is easier even when the user's hands are full.

They are easy to install and virtually maintenance-free.

Accessories available:

  • Angular mounting bracket.
  • Door opening edging profiles

The flap flexible doors in PVC, available in a double-door version, consist primarily of a sturdy structure in galvanised steel (painted or optional stainless steel) that sustains a flexible skirt of transparent PVC, suitable for use with positive temperatures or, upon request, with low temperatures, conveniently reinforced in high-stress points and complete with a torsion-spring reclosing mechanism.

They are available in 3 different versions:

  1. Manual (as described above), operates with a simple push
  2. Pneumatic touch, complete with actuation device consisting of two-way pneumatic pistons that allow the doors to open with a light push, in both directions, with a spring catch.
  3. Electro-pneumatic, complete with actuation device consisting of one-way pneumatic pistons that allow the doors to open, in a single direction, following the activation of a remote control such as a photocell, radar, metal detector, button or pull-cord, with a torsion-spring reclosing system.
