CRC Isothermal Door FX

The flap doors in PVC (flexible doors), 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:
Manual (as described above), operates with a simple push.
Pneumatic touch, complete with an 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.
Electro-pneumatic, complete with an 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.
