Explosion protection in the coal handling sector

With Q-Rohr, we provide the best possible explosion safety guarantee while using the optimal layout for your production facility.

Safety and operational efficiency can coexist. Q-Rohr enables explosion venting without flames or dust in a sealed indoor environment. There is no need for complex ducting and the associated rearrangement of production equipment for outdoor venting. With Q-Rohr, we provide the best possible explosion safety guarantee while utilizing the optimal layout for your production facility. Furthermore, Q-Rohr is also very advantageous in terms of running costs. By eliminating vent ducts, you can save not only on installation costs but also on maintenance and upkeep expenses. ▶ Applications Q-Rohr is ideal for indoor installations where there is a risk of dust or gas explosions. It offers a wide range of flexible installation options, so many new plants are directly equipped with Q-Rohr. Modifications are also easily possible. Q-Rohr can be used to protect filters, dryers, and cyclones, and is applicable for gases, hybrid mixtures, metal dust, molten dust, fibers, and more. ▶ Mechanism Flame gases reaching up to 1,500°C are cooled very efficiently within a specially developed stainless steel mesh filter inlet by REMBE. This reduces the amount of gas discharged and helps to quell explosions.

Explosion vent for vacuum or zero to low pressure.

【Application】 The EGV type is suitable for a wide range of applications, including spray dryers, elevators, chain conveyors, light vibration screens, mechanically filled silos, cyclones, and more. It can accommodate both non-pressurized processes and low vacuum or overpressure processes (up to 50% of the static burst pressure) and is usable in various fields. The standard burst pressure is 0.1 bar at 22°C (71.6°F). 【Benefits of Use】 ★ The lightweight burst surface allows for large capacity discharge with full bore opening. ★ It features high stability and a bionic structure that bursts at high speed. ★ Even with cylindrical containers or devices, explosion discharge ports can be directly attached, protecting against powder accumulation and bacterial growth. Complicated flange fittings for installation are not required. ★ Various shapes of the EGV type are available, perfectly adapting to the process. ★ The design of the rupture disk function is less affected by tightening torque, allowing for quick and easy installation without the need for additional mounting frames. ★ The explosion discharge ports with integrated mounting frames and gaskets enable significant space savings. ★ Unique inspections are conducted to guarantee a sealed structure.

Explosion venting port resistant to low to medium vacuum and pressure fluctuations.

The dome-shaped single-layer explosion vent type EDP is suitable for use in processes involving medium vacuum or overpressure (up to 70% of the minimum pressure (Pstat) when the explosion vent is open), as well as some pressure fluctuations. It is mainly suitable for air-filled devices, filters, cyclones, and containers that operate under strong vibrations. The standard burst pressure is 0.1 bar (22 °C). 【Mechanism】 As the pressure increases, the explosion vent will rupture at the designated rupture point at the specified pressure, releasing the pressure and flames from within the container or device to the outside.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

A "non-contact switch" that allows you to open and close doors simply by waving your hand, without directly touching the doorknob or switch! By adopting microwave technology, the risk of malfunction due to condensation in environments with temperature differences, such as cold storage warehouses, is significantly reduced. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, hospitals, nursing facilities, and restaurant kitchens. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ Waterproof and dustproof (IP55 design), allowing the main unit to be washed with water (note: the wall surface (back side) is not applicable) ○ LED display and response sound allow for easy confirmation of detection status ○ Two pattern settings for one-shot and latch output are possible ○ The thinnest in the industry! Only 22mm thick! ◎ For more details, please download the catalog or contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
