The Challenge
ARKEMA is operating its plant in a non-stop mode requiring a high level of availability of the equipments as utilities devices as compressed air tanks. To allow high availability of its plant, ARKEMA decided to go for LESER’s new Changeover Valves.
Why did the customer choose LESER products?
For ARKEMA, quality and reliability are the most important decision criteria to decide on Safety Valves and Change-over Valves.
More efficient plant operation with LESER Change-over Valves
The LESER Change-over Valve Type 330 and 320 offers the solution for safe and efficient system availability 24 / 7. It is easy to operate and, in combination with safety valves, provides permanent protection for a permanently running system.
With the help of flow tests and CFD simulations (Computational Fluid Dynamics), a flow-optimized design with minimal pressure loss was developed. Each configuration of these change-over valves has a specified resistance coefficient that enables reliable and precise calculation of the inlet loss. Due to their durable construction, these change-over valves are maintenance-free and lavishly tested. They are the economical solution because an optimal selection can be made for every application.
About the customer
ARKEMA is one of the leading hydrogen peroxide producers in the world. Hydrogen peroxide (H2O2) is used in different concentrations as example for food packaging sterilization. The plant in Shanghai was established in 2000, and expanded in 2008.
