Powder & Bulk Handling

Protecting life and equipment within applications at risk of deflagrations and explosions within the powder and bulk handling processes

The powder and bulk handling process contains many applications and pieces of equipment requiring deflagration venting protection at various pressure levels, temperatures, shapes, and sizes. OsecoElfab is dedicated to ensuring that your employees, equipment and applications remain safe each and every day.

Our customer-focused explosion protection portfolio includes the innovative Xplo-Gard, flameless vent designed for ease of use and maximum efficiency. Explosion panels, burst detection and rupture discs extend our range of specialist pressure relief solutions for the powder bulk industry.

Xplo-Gard is easy to use and offers safe, accurate flameless venting with maximum efficiency. Innovative features include an access hatch, which allows you to attach the vent body to the ductwork or vessel and then easily install the explosion panel inside it. Inspection windows mean you can easily inspect dust levels and check the panel’s status with no need to de-pressurize the system.

In the event of an unforeseen deflagration or explosion our explosion panels relieve the pressure wave that could otherwise lead to a significant safety event with the facility risking life and equipment. OsecoElfab manufactures a full line of explosion panels for a broad range of applications from dust collectors to bucket elevators. Our products are custom engineered and designed per NFPA 68 specific to your application and equipment rating. Our engineers also provide support with sizing/venting calculations assuring that the proper vent selection.

Our product range covers the standard industry pressures, sizes, and materials as well as specialty vents outside the common specifications. Contact us to discuss your custom requirements in more detail.

Innovative explosion protection

We know that one size does not fit all, so we offer a curved version of Xplo-Gard for mounting directly on to cylindrical vessels with no mounting flange, a sanitary version for food and pharmaceutical environments, and heavy-weight and light-weight versions to accommodate a wide range of pressures. Xplo-Gard also offers the largest size range for flameless vents on the market, so you can be sure of finding a vent that meets your specific requirements.

Xplo-Tel is an ATEX certified burst sensor designed specifically for use with flameless vents. We equip Xplo-Gard with the Xplo-Tel sensor as standard. The inductive sensor does not break when the panel bursts. It can be re-used for a new panel with no need for re-wiring. SVT-03 and Vent-Tel offer non-invasive, ATEX approved, reusable burst detection for explosion vents and panels.


Inventory Management Support
Our Explosion Vent Stocking Program allows you to receive vents at a reasonable cost when you need them in a hurry.

Explosion Protection Engineering Support
Our Technical Support team is there to provide engineering support with the vents, whether that is sizing, guidance per NFPA 68 and NFPA 652, documentation or pressure management advice.

Explosion Vent Sizing Worksheet

Our Vent Sizing Worksheet can help you determine the vent that will ensure your safety and protect your equipment. It covers areas such as:

  • Operating Pressure/Temperature
  • Vacuum
  • Number of cycles per day
  • Burst Pressure/Temperature
  • Kst and Pmax
  • Vent L/D ratio
  • Vessel Volume

Agribusiness Conveying & Bucket Elevators

Many different types of dust are found in the agricultural industry. Sources include grain, cotton, and flour. Many, if not all, are moved from one location to another through different methods of conveying. These include pneumatic, screw, or belt systems or through the use of a bucket elevator system. Each of these needs explosion venting. The code requirements for conveying systems can be found in NFPA 61.

Agribusiness Storage

Agricultural dust is just as deadly in a silo as it would be in a conveying system. Fine dust is always present in silos containing wheat, corn, flour, and other agricultural products. Proper venting can help reduce the damage of a contained deflagration.

Biomass Facilities

Biomass facilities such as wood processing plants, sawdust mills, and sewage works often involve a hazardous mix of dust, gas, and vapour. As a result, they present a real explosion risk that needs effective management. The design of a biomass system should therefore include a pressure relief device, such as a rupture disc (bursting disc) or an explosion venting panel. As the weak point in a pressurized process, vessel, or silo, the disc or panel is designed to burst at a set pressure before an explosion can occur.

Metalworking Dust Collection

The dust a metal shop produces is divided into two general categories: 1) Large dust particles, chips, shavings and 2) fine metal dust. The fine metal dust is extremely combustible and a collection system needs the correct vents to prevent catastrophic deflagrations.

Plastic Baghouses

When it comes to protecting a baghouse or dust collector, you need a vent that can withstand extreme vacuum conditions to maximize your collector’s potential. OsecoElfab offers specially designed vents for baghouse applications.

Plastic Bulk Storage

It's not just wood dust that is dangerous. Dust from rubber, grain, sugar, plastics, metals, and other materials are as hazardous or even more so than wood dust.

Powder Bulk Storage

In many industries, working with and storing powders are a critical part of the manufacturing process. Managing such substances requires special attention with regards to explosion venting. OsecoElfabs explosion vents are a critical part of the safety systems required.

Common Applications

  • Dust Collectors
  • Silos
