Description Vendor

The primary product is the **Explosion Vents** offered by OsecoElfab. These vents are designed for industrial applications where pressure relief is critical to safety. They come in two main types: **multi-layered** and **single-skinned**. Multi-layered vents combine layers of stainless steel and fluoropolymer to create a high-performance solution, offering a dust-tight seal, non-fragmenting properties, and excellent corrosion resistance. They are available in various shapes (square, rectangular, round, trapezoid) and configurations, with a wide range of bolt patterns. The domed design of multi-layered vents provides an operating ratio of up to 80%, making them highly effective under cyclic pressure, back pressure, and vacuum conditions. Single-skinned vents are a cost-effective option, also featuring a dust-tight seal, non-fragmenting properties, and resistance to abrasion, corrosion, and moisture. They are suitable for low-profile applications and offer higher stability in medium vacuum conditions. Both types are certified for ATEX compliance and are available in custom sizes with optional accessories like frames and gaskets. The vents are designed to ensure fail-safe, rapid, full venting and are ideal for use in silos and other industrial environments.

Use Cases

  • Low-profile installations (e.g., silo construction)
  • Applications with cyclic pressure, back pressure, and vacuum conditions
  • Medium vacuum environments (single-skinned domed vents)

Capabilities

  • Provides explosion pressure relief within a defined burst pressure range (0.05–0.49 barg)
  • Operates across temperature ranges depending on design (−40°C to 200°C multi-layered; up to 80°C single-skinned)
  • Supports operation under cyclic pressure, back pressure, and vacuum conditions (domed designs)
  • Available in multiple geometries and sizes to match installation requirements
  • in multiple geometries and sizes to match installation requirements
OsecoElfab OsecoElfab, a global manufacturer of customized rupture discs (bursting discs), explosion vent panels, flameless vents, and burst detection sensors with over 50 years of experience supporting EPC firms, provides pressure relief and explosion protection solutions for the hydrogen safety industry, addressing the reality that hydrogen storage tanks and transport systems require high-integrity, fail-safe pressure relief devices to prevent system pressure from rising above 10% of maximum allowable operating pressure. The company's rupture discs and explosion vents meet the required standards for hydrogen safety, offering exceptional leak-tightness with reliability and accuracy for peace of mind across hydrogen equipment, positioned within a comprehensive product portfolio including the LoKr reverse buckling rupture disc, Oseco Safety Cartridge (a two-piece unit combining traditional three components into one hermetically sealed device), Opti-Gard (95% operating ratio, industry-leading burst tolerance), and PRO+KRGL (best-in-class Flow Resistance Factor) for high cycling performance and demanding applications. OsecoElfab addresses hydrogen's unique storage challenges given that hydrogen is not an energy-dense fuel and must be stored in liquid form or under extremely high pressures and low temperatures to achieve practical energy density for vehicle range, requiring customized design and engineering support from OsecoElfab's pressure relief experts to ensure the right solution for each hydrogen plant, equipment, or vehicle application. Serving industries including chemical processes, refining, energy, pharmaceutical, biotech, industrial gases and cryogenics, electrical energy storage/batteries, and aerospace/defense/propulsion, OsecoElfab continues supplying customized rupture disc and explosion protection solutions supporting the safe storage, transport, and use of hydrogen across the growing global hydrogen economy.
