CIRCOR Tech NeSSi ™ Product Development & Market Snapshot

1. CIRCOR Tech NeSSi™ Product Development & Market Snapshot Patrick Lowery IFPAC 2007, 1.29.07

2. “Just Yesterday”

3. Technology Roadmap NeSSi™ Roadmap End of 2007 (full IS and Control Solutions available TODAY (Gen 2) Only 6 months ago (“Gen 1.5”) Initiative started 6 years ago NeSSi™ is a trademark of the Center for Process Analytical Chemistry, University of Washington

4. Progress • At present, CIRCOR Tech has built and lab tested several different categories of sample system devices based on the Siemens I2C Maxum™ GC Digital Bus • Pressure Sensor • Solenoid Pilot Valve • Fluid temperature probe • Pressure, flow combination sensors • 2nd iteration with IS design circuits are in process for • All the above components, plus • Multi-variable sensor (Pressure, temp, flow) • Low-powered combi-valve for closed loop, IS (Zone 1, Div 1), flow and pressure control • Filter monitoring modules Maxum™ is a trademark of Siemens Energy and Automation

5. CIRCOR Tech “NeSSi-Bus” Devices

6. Progress • In addition, preparations are being made to test power supply schemes for low powered CAN Bus as per the CiA (CAN in Automation) Intrinsically Safe CAN Bus Working Group • Working network of sensors, valves, and control devices will be online in late Feb according to proposed IS power supply and communication scheme • CIRCOR Tech Core sensing and control modules will have different bus flavors available according to end user or analyzer OEM preference (I2C, CAN Bus, Modbus, RS-485) • Will be working with CAN and other PLC and/or hybrid controller companies to bring control solutions for retrofit activity outside of smart GC’s

7. Progress • CIRCOR Tech has also co-developed a set of Microsoft “smart” Visio™ tools that will allow a future migration of standard modular or ISA P&ID symbols and system design graphics to have some portability into a live XML-based HMI or GUI for sample system control and visualization

8. Is this a success? We are still here!!! Significant achievements so far, but far from success

9. What’s Next? • Mainstream customers will not adopt a “discontinuous” technology without: • Having the “whole product concept” fulfilled • Having the entire core product (s) augmented by EVERYTHING that is needed for the customer to have a compelling reason to buy • Distributors or sales people skilled in the new technology • Good warranty, strong company, and strong support • 2nd Sources and a Competitive Marketplace • This includes the product (s) along with training, support, manuals, cables, connectors, accessories, additional hardware and software, etc. • Example: One cannot implement an IS CAN Bus solution without a certified IS Power Supply, an IS CAN Bus Isolator Repeater, Special Cabling, Wiring Documentation, and Config. Software

10. What’s Next? Being developed • Example of IS CAN Bus Network (courtesy of CiA IS CAN Bus working group Needs further development and certifications Being developed

11. What’s Next? • What is still needed to fulfill the Whole Product Concept for Digital Bus? • More power supply components • Repeaters, Isolators, and Barriers • Connectors and Cabling • Configuration Management Software • A Standalone SAM (Sensor Actuator Manager) for non-GC analyzer applications with HMI • What is needed for overall NeSSi system success? • End users must “change behavior” in order to adopt a discontinuous technology innovation • At a certain point, innovation must cease to allow customer to digest what is currently being offered. Otherwise, they are waiting on the next revision

12. What’s Next? • Examples of what to expect • Digital bus system maintenance will require software and hardware interaction between analyzer and sample system • Could get stuck in information overload mode if streaming data is provided rather than mission critical decision making information • Sample system purge systems go away, potentially exposing the digital devices to concentrated chemical vapors continuously • Compromises may have to be made to make digital bus sensors cost effective in these extreme environments • IP65 ratings a necessity, corrosive resistance a must, 85 deg C operation • Hot Swap, Plug and play, C1D1, Zone 1 (possibly Zone 0) certifications become necessary • Digital devices must be field addressable rather than “software addressable” which means that windows, access ports, must be available • Some sort of visual indication of system health would be desirable rather than going back and forth between SHS and analyzer • CAN IT ALL BE ACHIEVED COST EFFECTIVELY???

13. What’s Next? • Examples of what to expect, cont. • Energy budgets will become important due to the relatively high cost per milliwatt of special IS power supplies • Terms like “average cost per node”, and “average power per node”, will used to as a technical selling advantages for smart digitally controlled sample systems • Multi-function, multi-variable devices will be leveraged to gather multiple pieces of information with a single bus node, minimizing connection cost • Digital bus node functionality and failure modes (FMEA) will have to be taken into account when performing system design and safety reviews of smart sample systems • Will integrators adopt this responsibility quickly?

14. Summary • CIRCOR Tech has developed, and is continuing to develop, solutions for this emerging technology • Things are starting to get exciting, but require complete follow through by multiple parties to bring whole product concept to market • Will need a complete change in mentality of how systems are designed, built, integrated, and maintained
