MDC Precision uses mass flow control for XpressStick gas delivery module

The XpressStick™ MFC Gas Stick MDC Precision has designed an all-in-one solution, eliminating complex hardware specifications in a combination of specialty gas, pressure, precise regulation, and vacuum processes. Its easy programming and precise gas control system allow users to go from bottle to process in one simple step. Designed to meet ultra-high purity process requirements, the XpressStick is also offered in a stainless steel model for corrosive environments.

XpressStick™ MFC Gas Stick with vacuum mass flow controller

“Fast response time, accuracy, and reliability were all key criteria in choosing an MFC instrument for our XpressStick. Based on past experience with Alicat, we knew that they could deliver all three, with an integrated display that enables our all-in-one design.” 

– MDC Vice President of Engineering & Technology, James Moore

MDC integrated Alicat vacuum mass flow controllers into their XpressStick™. The mass flow instrument precisely controls gas flows of up to 20 SLPM with real-time mass flow, volumetric flow, absolute pressure, and temperature measurements. It also provides gas programming functionality to the gas connection module, which links pressurized gas inputs to vacuum chambers. An integrated display allows for the gas module to be programmed directly from the device, and gas type can be easily switched between 98 onboard gas calibrations.

With 30 ms control response times to setpoint changes, this device improves MDC’s vacuum coating end products and helps eliminate target poisoning. Additionally, no warm-up time means the XpressStick is ready to control process flows in just one second.
