Description Vendor

OsecoElfab’s MV-RD is a metal vent designed for high cycling applications such as dust collectors, bag houses, and bulk storage units that require a rectangular vent. It is specifically engineered to safely relieve pressure in the event of a deflagration, thereby preventing a large explosion. The MV-RD is suitable for applications that experience vacuum pressure up to 12psig/24.4 inHg and can be exposed to system pressures up to 80% of the stamped burst pressure range. Its high cycling characteristics reduce maintenance and increase the vent’s life cycle. The MV-RD is made from 316 stainless steel and features a non-fragmenting design, ensuring safety and durability. It meets NFPA 61 and NFPA 68 regulations and is available in a range of sizes from 12 x 12 to 36 x 44. The product comes with a 2-year warranty and is ideal for use in ductwork, bag houses, bulk storage, and dust collection systems.

Use Cases

  • Bag houses
  • Dust collectors
  • Bulk storage units
  • Ductwork

Capabilities

  • Provides explosion pressure relief in deflagration events for enclosed systems
  • Suitable for high cycling pressure environments, improving service life
  • Can operate under positive pressure (up to 80% burst pressure) and vacuum conditions (10–12 psig range)
  • Designed for rectangular mounting on industrial enclosures (dust handling systems)
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.
