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
