EGGER and IEP Technologies join forces

Since 2001, EGGER – a leading manufacturer of wood-based materials headquartered in Tyrol – has relied on systems from the HOERBIGER company IEP Technologies. What began as a single safety measure has evolved into a comprehensive protection strategy. The Unterradlberg site, which opened in 1970 and specializes in the production and coating of chipboard, processes around 650,000 m³ of wood annually – making safety a top priority in this complex production environment.

Smart factory with a focus on safety
“In 2023, our site in Unterradlberg was honored with the ‘Smart Factory’ award as Austria’s most innovative production site. This recognition is both validation and motivation for us,” says Martin Wurzl, Plant Manager for Technology and Production. “EGGER is defined by a holistic approach to automated and networked production. Process optimization systems are essential – including those related to safety and explosion protection.”

At the core of the safety strategy lies a multi-stage, ATEX-compliant protection concept. By combining flameless pressure relief, detection, suppression, and decoupling technologies, hazards are identified and mitigated at an early stage. Chip drying is particularly critical, as wood with less than three percent residual moisture is processed here, and even a small spark can have dramatic consequences.

Millisecond-level response
These systems respond within milliseconds to pressure changes or flame detection. Sensors identify potential explosions before they occur, triggering the release of extinguishing agents. Integrated flame barriers and decoupling mechanisms prevent explosions from propagating through connected duct systems. “When we needed to expand our protection, it became clear that IEP offered the best solution. We could build on existing systems and our long-standing collaboration,” says Thomas Pöll, Maintenance Manager at EGGER.

A key milestone was the integration of flameless EVN valves. Their compact design makes them ideal for use in EGGER’s vibration and screening systems. Since 2023, IsoDisc systems have also been in operation to prevent explosions at backflow openings.

A long-standing partnership based on trust
Cooperation between EGGER, IEP Technologies, and the machine manufacturers was a decisive factor in the project’s success. “The close coordination between EGGER, IEP, and the screening system manufacturer enabled precise planning and implementation of the safety measures,” Pöll explains.

Maintenance and inspections are carried out regularly. IEP Technologies performs annual servicing during planned shutdowns, while EGGER conducts internal inspections every two months. This ensures the system remains reliable – even in an emergency. “Safety and occupational health have always been top priorities at EGGER. That’s why we made the decision to invest further in preventive fire and explosion protection,” says Pöll. The installed systems have proven their worth: “They work reliably, and the personal support – especially during process disruptions or repairs – is extremely valuable.”

Safety as a shared responsibility
Beyond the technology, it is the active partnership that underpins the project’s success. Built over 25 years, this collaboration is founded on trust, technical expertise, and continuous improvement. Thanks to cross-site safety reporting across all 22 EGGER plants, the company stays up to date – and continues to set industry standards in both safety and sustainability.

Markus Häseli, Managing Director at IEP Technologies Europe, sums it up: “The implementation of the multi-stage explosion protection concept at EGGER’s Unterradlberg plant clearly demonstrates how well-designed safety solutions can effectively reduce risk and protect both people and equipment. With this approach, EGGER is setting new standards in industrial explosion protection.”
