The Quench Valve QV II and QV III are explosion isolation devices installed in pipelines to contain explosions at designated points within the equipment. The quench valves are connected to a controller (EXKOP Express or EXKOP TriCon)*. When an explosion occurs, the controller receives a trigger signal (for example, from a Q-Rohr or rupture disc signal device, pressure switch, spark detector, etc.) and activates the connected quench valve, closing it within a few milliseconds. This prevents the propagation of the explosion. After activation, it can be returned to a reusable state simply by pressing a button. ▶ Additional features: ▸ Spark arrestor (e.g., between the mill and product filter) ▸ Overpressure limiter (e.g., between silo trailer and silo) * For more detailed information about the controller, please refer to the product information of related products.

In industrial drying equipment, it is necessary to consider the risks of fire and explosion. When the properties of the fluid change, the risk of ignition or explosion increases. This is particularly true for spray dryers, where caking can occur if process control is not optimal. Additionally, the material may be heated to the point of triggering the Maillard reaction during operation. This is due to exothermic reactions occurring between proteins, carbohydrates, and moisture. The heat generated accumulates without being dissipated until self-ignition begins. Such heating phenomena can pose a risk of igniting existing explosive atmospheres or mixtures. The concentration of carbon monoxide (CO) during the process is used as a parameter for early detection.

"SYMEGA.VO" is a grounding monitoring device that continuously monitors the grounding status of electrical equipment and detects abnormalities early, thereby reducing the risk of explosions due to electrical troubles. It has a wealth of implementation experience in various fields such as process industries, chemical industries, and pharmaceutical industries.
