Flow Control (Gas / Liquid): Semiconductors, Flat Panel Displays and even Photo Voltaic Solar Cells are involved in an ever increasing part of our lives.

To manufacture these high tech devices it is important to have reliable and precise Fluid Control. HoribaSTEC is the established world leader in this area offering a full line up of Gas, Liquid, and Vapor delivery products. The company also proposes a range of liquid vapor sources for point of use chemical vaporization. 

HoribaSTEC has released to market an MFC model with Profibus as the communication protocol. Profibus is normally not used by the semiconductor industry but is seen often in other segments of the coating industry. The N100 has many construction similarities to the Z500 series, which has enjoyed worldwide success over past years and which has been adopted by many equipment OEMs as their main MFC. Until recently Horiba could only propose the DeviceNET communication option. The N100 is also available both with all metal seals or Viton seals.

 xtronix custom designs removes the burdensome task of design engineering, parts procurement, assembly, testing and final qualification. We work with suppliers, often companies we actively distribute products of, to obtain the best price and delivery, leaving our customers more time to focus on their own clients and less time worrying about all the intricacies of custom designs.

In addition, xtronix, with its global resources and cutting edge know-how, is often times able to procure custom sub-parts in small quantities. 

We can also custom design & manufacture your gas panels as well as more complex gas blending systems.
