Applied Energy Systems Develops Ultra High Purity (UHP) Silicon Tetrachloride (SiCl4) Delivery System to Support Fiber Optics Cable Manufacturing

AES’ Expansive Applied Solution Combines Multiple SEMI-GAS® and VERSA-GAS™ Systems for Bulk SiCl4 Delivery

MALVERN, PA, APRIL 28, 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 the latest Applied Solution it developed for a leading global telecommunications cables producer to support the company’s fiber optics cable manufacturing. The Ultra High Purity (UHP) Silicon Tetrachloride (SiCl4) Delivery System is an expansive solution that combines multiple SEMI-GAS® subsystems and controllers, installed across different rooms, with customized VERSA-GAS™ liquid delivery boxes mounted on a high bay steel bridge to push liquid SiCl4 from source tube trailers to the various subsystems.

AES’ custom solution was tailored specifically to the cabling provider’s high-tech manufacturing processes and operating environment. In addition to the source liquid push boxes, the system includes:

  • A secondary set of liquid push boxes installed in the facility’s gas room to supply the system’s day-tank and ultimately feed the manufacturer’s process system.
  • A SEMI-GAS® 500 liter SiCl4 316 L stainless steel day tank and Xturion™ LPX™ enclosure for filling and delivering liquid SiCl4.
  • Two wall mounted SEMI-GAS® GigaGuard™ PLC Controllers with color touchscreens: one for monitoring and emergency shutdown of the day tank system and associated liquid push boxes, and one for monitoring and emergency shutdown of the source liquid push boxes. The controllers have been integrated to communicate with each other for seamless monitoring management.
  • A system design and footprint which allows for future expansion and includes a SiCl4 isolation box for splitting and feeding two duplicate systems.

The system was not only engineered by AES, but installed and tested in the cabling manufacturer’s facility by AES’ Applied Services field team. Services provided included equipment installation; ultra high purity process piping and coaxial line installation to interconnect all system components; on-site helium leak testing and system validation; and equipment commissioning and staff training to ensure optimal system operation.

“The expansive nature of this custom UHP delivery system makes it critical for every component to function cohesively together,” said Jim Murphy, General Manager of Applied Energy Systems. “Our equipment engineers have once again delivered a robust, reliable system that is uniquely custom-built to the needs of our customer, and our field team provided the expert services to streamline implementation of that system for use. With our combined offerings, we were able to simplify a complex challenge for our customer and give them the tools to continue to advance their fiber optics cable manufacturing operations.”
