One of our customers processes a wide variety of materials in its mixing process, including barium sulfate, metal powders, thermosets, and fibers. To ensure safe extraction, we designed and installed a custom-engineered extraction unit with tertiary explosion protection.

A P 7000 series deduster (22 kW | 23,000 m³/h) is used, featuring an ATEX-compliant design and custom paint finish according to the customer’s specifications.

Emissions are captured right where they are generated: via several ATEX extraction arms mounted on wall brackets or floor stands, via machine connections, and directly at the filling station.

A side-mounted pre-separator removes larger particles. Any remaining dust is then captured by the filter cartridges of the extraction unit. The fully automatic, differential-pressure-controlled jet-pulse cleaning system dislodges the adhering dust from the filter elements, ensuring reliable and trouble-free system operation. In addition, the system is equipped with a HEPA H14 filter stage.

For tertiary explosion protection, the system is designed with a pressure-resistant construction. Two flameless explosion dampers in the raw gas chamber enable flameless pressure relief in the event of an incident. On the clean gas side, a check valve provides explosion-related decoupling. On the return air side, a rupture disc with a signal transmitter is additionally integrated for explosion pressure relief. To monitor the compressed air supply, the system also features a pressure monitoring kit for the compressed air tank. 💪

The separated dust is continuously discharged via a rotary valve and fed directly into a BigBag provided by the customer.

The system also offers flexibility in terms of airflow: A summer/winter switch allows you to toggle between recirculation and exhaust modes. Especially during winter operation, recirculating the purified air can help reduce heat loss and, consequently, the energy required to heat the facility. 🌱
