Metal pneumatic KD flood doors are installed in buildings where there is a possibility of flooding. The doors ensure a perfect water seal up to a height of 3 m as long as they are installed in a watertight wall, since the doors are completely flood-proof.

INSTALLATION:

The installation of the frame of a flood door must be performed in conjunction with the construction, i.e. the concreting of the wall. The frame of the door must be covered in watertight concrete.

SPECIAL FEATURE:

An important advantage of the door is that it is level with the levelling floor, so the passage through the door is not obstructed for any means of transport.

The door and the frame are manufactured from a solid steel construction. The door can also be manufactured from stainless steel.

DOOR DIMENSIONS:

Minimum dimensions (mm)

1100 x 2000

Maximum dimensions (mm)

1900 x 2500


PROTECTION:

The doors are double powder-coated, which ensures a total coating of 120 microns.

The colour can be selected from the RAL colour chart.

The doors have class C3 corrosion protection in accordance with DIN55633 and EN ISO 12944 standards.

STANDARD EQUIPMENT OF PNEUMATIC KD FLOOD DOORS:

  • silicone seal in the form of an inflatable tube;
  • pneumatic mechanism operating at a voltage of 12 V;
  • bolting lever which triggers the operation of the pneumatic mechanism;
  • batteries which enable the operation of the door for up to three weeks in the event of a power failure.

The doors are closed and opened manually. When the doors are closed with the bolting lever, the pneumatic mechanism fitted in the leaf of the door is triggered. This mechanism inflates the seal which fills the gap between the frame and the leaf of the door. The working pressure in the seal must be 1–2 bar. A pneumatic KD flood door is fitted with two inflatable silicone seals (double sealing) which are regulated separately. This ensures the reliability of the product.

As a result of the pneumatic mechanism, the closing and opening of the door is simple and effortless. When a risk of flooding has been predicted, the doors must be closed manually. The doors can also be upgraded with a powered automatic closing mechanism and a sensor for measuring the water level. In the case of a raised water level, the doors close automatically.
