Explosion Control & Hazardous Area Protection

Explosion Control & Hazardous Area Protection

Purge and pressurizing solutions are critical techniques employed in various industries to ensure the safety and integrity of equipment, systems, and environments. These methods are especially prevalent in sectors dealing with hazardous substances, explosive atmospheres, and sensitive processes where maintaining controlled conditions is paramount. Purging and pressurizing techniques are designed to create controlled atmospheres within these spaces, preventing the intrusion of undesirable elements and maintaining controlled conditions for optimal functionality.

We specialize in comprehensive site assessment surveys tailored specifically for purged and pressurized panels. Our focus is on understanding the challenges and intricacies associated with these panels, enabling us to propose effective solutions for rectification. Our site assessment surveys serve as a foundation for optimizing the performance and safety of your purged and pressurized panels. By identifying issues and providing actionable solutions, we empower you to enhance your operations, mitigate risks, and ensure that your panels operate at their full potential.

Purge and Pressurisation Safety Device

Purge and Pressurisation safety device ensures the safe operation of electrical machines (Motors, Generators, Compressors etc.) and enclosures within Zone 1/21 and 2/22 hazardous areas.

This is designed in accordance with IEC 60079-2:2014 Ed 6/ EN 60079-2:2007, ensuring a pressurised and leakage compensated enclosure. This creates a non-hazardous atmosphere inside the enclosure by keeping a positive differential pressure between the pressurised enclosure and atmospheric pressure to ensure that no potentially explosive gases enter the electrical equipment.

This Type of Protection Consists of Two Main Stages

Purge Cycle

Activated when the electrical machine is OFF prior to being switched ON. Clean air/inert gas is blown through the machine and monitored to ensure compliance with IEC 60079-2/ EN 60079-2.

Leakage Compensation and Pressurisation Cycle

Once purge cycle is satisfactory the machine is considered non-hazardous and ready to be switched ON. A positive differential pressure to atmospheric has to be maintained. This is achieved by compensating for any air/inert gas leakages that the machine might experience.

Custom Solutions

Our specialty is providing tailored or custom Explosion Protection enclosure & panels solutions suitable for Zone 1 & Zone 2. So, if you need to populate your existing products for use in hazardous areas, our team will help determine the right enclosure configuration to meet your operational needs and achieve a fully certified end solution.

Our expertise in bespoke explosion protection solutions across a range of electrical and non-electrical equipment provides customers the confidence to explore market growth opportunities for their existing products.

For example, if you need a populated explosion proof enclosure but don’t know how to achieve the full certification requirements, we can undertake the project for you and deliver a completed product ready to install with all associated documentation and approvals. Whether it’s all electrical, all mechanical or a mixture of both we have the experience to support the project.

We will select products from our extensive range of enclosures and ancillary equipment and source other suitable 3rd party products to meet the full scope.

Our skilled production team can pre-populate the enclosures with your donor parts and our sourced parts, ready for your final installation on site.

Each enclosure solution will be provided with a final certification document pack.

We work with electrical panel builders and OEMs across a wide range of industries, including oil & gas, chemical & petrochemical, pharmaceutical & biotechnology, and power generation to design, build and certify hazardous area enclosures & panels to customers exact requirements for both gas and dust service.
