SEMI-GAS® Systems, a supplier of ultra-high purity gas source and distribution systems with robust control technology, has expanded the capabilities of its Xturion™ Blixer™ Gas Mixing Blender to now support specialty ammonia mixtures. Part of its premier line of custom-engineered gas equipment, the Blixer Gas Mixing System for NH3/N2 uses a PLC-based system controller to mix external sources of ammonia and nitrogen gases into an internal accumulator tank, with the output then supplied to the process line. This programmable mixing functionality provides efficiency and versatility to operators, allowing them to mix their specialty ammonia gases on-site and in the specific mixing percentages they need, instead of having to purchase costly premixed gas cylinders.
Configuration of the PLC and monitoring of the mixing system is done via an 8” colour LCD touch screen interface, with mass flow controllers regulating the volumes of each gas to be blended according to the programmed recipe. The PLC controls pressure and flow within the operator’s preset ranges, ensuring flow cycling that maintains accumulator tank pressure to continuously supply gas to the process line.
Analytical reports are included to show that the system has met or exceeded SEMI-GAS®’ standard acceptance criteria of less than 100 ppb for Moisture and Oxygen, and 5 Particle counts per cubic foot of 0.1um–0.3um.
