DonadonSDD Explosion Vent Panels

DonadonSDD explosion vent panels are non-reclosing pressure relief devices designed for process equipment where there is a risk of dust or gas deflagration. When the set opening pressure (pstat) is exceeded, the panel ruptures, venting overpressure in a predetermined safe direction.

Construction and Technical Data

Standard construction is composite and includes:

  • calibrated metallic section,
  • sealing membrane, typically PTFE,
  • protective metallic cover.

Available models: PS/R (rectangular geometry) and PS/C (circular geometry). Typical parameters: burst pressure 0.1 bar g, tolerance ±10% to ±20%, operating temperature up to 260°C, operating margin 50–70%. Options include vacuum support and electrical or inductive activation indicators.

Process Applications

Common installations:

  • dust collectors and bag filters,
  • silos and bulk storage vessels,
  • dryers, sifters, and separators,
  • mixers, troughs, and conveying lines,
  • air systems, boosters, air purifiers.

Suitable for static, pulsating, or cyclic pressure loads in the presence of gas and/or combustible dust.

Standards and Certifications

ATEX PS/EX versions are certified EX II GD or EX II D. Technical documentation confirms compliance with ATEX 2014/34/EU and protection type per EN 14797 for explosion venting devices.

Model Selection

PS/R is selected for rectangular venting surfaces on filters, silos, or flat walls. PS/C is used for circular nozzles or flanged vessels. Selection requires: equipment volume, dust Kst/Pmax, allowable reduced pressure (Pred), temperature, vacuum, ATEX zone, and vent duct presence.

FAQ

Is replacement required after activation?
Yes. The panel is non-reclosing and must be replaced after opening.

Can it be integrated with automation systems?
Yes, via electrical or inductive activation indicator.

Is a machined frame required?
Installation is possible between welded frames or non-machined profiles in carbon or stainless steel.

Description

What is an explosion venting panel? How Does a rupture panel Work?

Explosion vents or rupture panels are crucial safety devices designed to protect personnel, equipment, and buildings from the devastating effects of excessive internal, explosion-incurred pressures. Explosion venting panels serve as a pressure relief mechanism, providing protection against excessive internal pressures caused by explosions in industrial processes. These safety devices are designed to open (or activate) when their opening pressure (pstat) has been exceeded, effectively relieving the pressure.

DonadonSDD specializes in non-self-reclosing explosion vents, featuring diverse shapes, materials, temperature tolerances, pressure resistances, and more. Find the perfect solution for your venting needs with our top-quality explosion vent panels, designed to excel in performance and meet industry standards.

Why choose DonadonSDD explosion venting panels for your industrial safety needs?

Our high-quality explosion vent panels provide optimal protection in various industrial applications where there's a significant risk of explosion due to the nature of the processed materials. Designed to yield under rising pressure and safely vent it, these panels are the ideal choice for critical safety points.

DonadonSDD explosion vent panels consist of three primary layers: a calibrated metal section, a protective base, and a PTFE holding membrane. We also offer panels with counterpressure support and ATEX, EX II GD, and EX II D certifications, if needed.

Suitable for use with gas and/or dust, our panels function well in static, pulsating, and cyclic conditions. They are ideal for installation on dust manifolds, dryers, troughs, silos, separators, mixers, boosters, air purifiers, sieves, and filters. With compatibility for carbon or stainless-steel frames, there's no need for machined frames or expensive containers.

Our ATEX certified venting panels can be installed in areas with explosive atmospheres, adhering to the European Directive ATEX 2014/34/UE classifications. DonadonSDD explosion vent panels are known for their simple installation process, minimal maintenance requirements, extended durability, and swift substitution following an explosion incident.
