Applied Energy Systems Develops Compact Fully Automatic SEMI-GAS® Centurion™ Mini Source System for Low Volume Gas Applications

System Combines Proven Centurion™ Design with GigaGuard™ CDM400 Controller for Operator Ease-of-Use

MALVERN, PA, AUGUST 31, 2017 — Applied Energy Systems (AES), provider of high and ultra high purity gas systems, services, and solutions – including design, manufacturing, testing, installation, and expert field service – has unveiled its new Centurion™ Fully Automatic Mini Source System to support low volume gas applications. The SEMI S2 compliant system combines SEMI-GAS’® ultra high purity standard Centurion™ gas source manifold and GigaGuard™ CDM400 controller to safely and precisely deliver gases from small, lecture bottle sized cylinders.

Key design highlights of the system include:

  • A compact, wall-mounted design which mimics the performance and precision of a full sized Centurion™ Source System.
  • A GigaGuard™ CDM400 Controller with a 4.3” color touchscreen, powered by a Siemens S7-1200 Series CPU to enable automatic purging sequences and ensure the system’s safe and intuitive operation. The CDM400 is configurable for 4 or 8 analog inputs and can control up to 12 solenoid valves.
  • Red, yellow, and green front-mounted LED lights and a high performance audible alarm to indicate system status, as well as a front-mounted pneumatic Emergency Off (EMO) button.
  • Transducer-based pressure monitoring and an Excess Flow Switch with user-specified set-points to trigger an automatic system shutdown during undesirable system conditions.
  • A Magnahelic and Switch Exhaust Monitor to indicate air and exhaust pressure differentials.
  • Z-Purge optional upgrade for Class I Division II compliance.

While the system can be tailored for an array of gases and UHP application requirements, AES initially developed the 1-Cylinder Mini Source System to support a semiconductor customer’s mixed signal, connectivity, and embedded systems research and development. The complete turnkey solution for Ammonia included AES’ Applied Services equipment installation; confirmation of system conditions, facility connections, component and EMO function; set up of automated purge routines; validation documentation; and operator training by AES field service experts.

“We strive to be a value-add partner for our customers, from system design to system installation, and the Centurion™ Mini Source System is another example of how our expertise can be leveraged from end to end,” said Jim Murphy, General Manager of Applied Energy Systems. “Not only did we help our semiconductor customer solve a specific delivery challenge– built upon our proven, premier SEMI-GAS® products – but our Applied Services team also helped them get their system up and running quickly, minimizing their process downtime and avoiding costly delays.”
