Specification Text for Tenders

METU-SYSTEM Insulated Access Door IRRD-DW1 with PE

Sturdy, press-formed access door for double-wall circular ducts or curved surfaces with various insulation thickness made of dished inner and outer cover plates which are pulled together thanks to two longer bolts and corrosionresistant knobs. In doing so the duct walls are clamped evenly between the two access door covers. The self-adhesive polyethylene (PE) gasket on the inner cover plate makes the access door air-tight even by higher pressures. The oval shape of the access door allows an easy installation into the opening.

METU-SYSTEM Insulated Access Door IRRD-DW1 with SKK (Rubber Edge Molding)

Sturdy, press-formed access door for double-wall circular ducts or curved surfaces with various insulation thickness made of dished inner and outer cover plates which are pulled together thanks to two longer bolts and corrosionresistant knobs. In doing so the duct walls are clamped evenly between the two access door covers. The self-adhesive rubber edge moldings (SKK) are applied along the relatively sharp edges of the duct opening and prevent eventual injuries while making the access door air-tight even by higher pressures. The oval shape of the access door allows an easy installation into the opening.

METU-SYSTEM Insulated Access Door IRRD-DW1 with GF Gasket and Metal Knobs
(for higher temperatures up to + 200°C)


Sturdy, press-formed access door for double-wall circular ducts or curved surfaces with various insulation thickness made of dished inner and outer cover plates which are pulled together thanks to two longer bolts and high temperature resistant metal knobs. In doing so the duct walls are clamped evenly between the two access door covers. The self-adhesive vitreous fibers wool (GF) gasket on the inner cover plate makes the access door air-tight even by higher pressures. The oval shape of the access door allows an easy installation into the opening.

METU-SYSTEM Insulated Access Door IRRD-DW1 with Silicon Gasket (Food Industry)

Sturdy, press-formed access door for double-wall circular ducts or curved surfaces with various insulation thickness made of dished inner and outer cover plates which are pulled together thanks to two longer bolts and corrosionresistant knobs (or metal knobs for operating temperatures between 80 and 200°C). In doing so the duct walls are clamped evenly between the two access door covers. A silicon profile-ring (SI) wrapped around the edge of the inner cover makes the access door air-tight even by higher pressures. The oval shape of the access door allows an easy installation into the opening.
