Brooks Instrument Launches Upgrades to GF 40/80 Series Thermal Mass Flow Controllers

April 24, 2013 - "Press Releases"

HATFIELD, PA (March 18, 2013) – As a world-leading provider of advanced flow, pressure, vacuum and level solutions, Brooks Instrument has expanded its GF 40/80 Series portfolio of thermal mass flow controllers. The expansion includes broader capabilities, including increased flow rated up to 50 slpm and a “normally open” valve for non-hazardous gas applications, are ideal upgrades for users of Aera (Hitachi), Celerity, Tylan, Mykrolis, Millipore and Unit mass flow controllers, as well as other competitive devices.

The GF 40/80 Series is leading the market in long-term zero stability at less than 0.5 percent per year. This means the device will return more reliable accuracy data fro a longer period of time, giving users greater confidence in the numbers reported. The series is also available with Brooks’ patented MultiFlo™ which is a powerful technology the enables users to re-program the gas and/or range in minutes without the cost or trouble of removing the mass flow controller from service. Brooks has expanded the flow rates for the GF 40/80 Series from 30 slpm to 50 slpm, making these devices an excellent choice for applications that require a higher flow rate with the flexibility of a MultiFlo-capable mass flow controller.

Newly expanded RS485 communication protocols increase the flexibility and application range of the GF 40/80 Series. These versions of the RS485 protocols are ideal for users of Aera (Hitachi), Celerity, Tylan, Mykrolis, Millipore and Unit mass flow controllers. The Celerity, Tylan, Mykrolis, Millipore and Unit brands are part of the Brooks product line following its acquisition of Celerity Instrumentation in 2009. These end users can now upgrade to a device that offers better accuracy and repeatability while keeping the same communication protocols.

The GF 40/80 Series also integrates the EtherCAT communication protocol, which is a high-performance, ethernet-based fieldbus system designed for process control applications requiring short data update times with low communication “jitter.” Adopted by leading-edge technology companies, EtherCAT makes it easier to network instrumentation for advanced process control and diagnostics capabilities.

Normally open valves are desirable in applications where it is preferable for the valve to remain open even if a facility loses power, so that the mass flow controller continues to provide maximum purge gas flow from the system. The GF 80 also features a new Teflon® valve seat. The valve seat is non-reactive, which allows the GF 80 to be used in applications for corrosive and reactive gases.
