Conax exhibits EtchDefender™ at SEMICON West

For the first time in the United States, Conax Technologies exhibited its new EtchDefender™ Technology at SEMICON West. EtchDefender™ is a proprietary coating that extends the life of quartz items exposed to temperatures up to 1200˚C and Hydrochloric etch cleaning cycles. This technology will allow parts to last longer and thereby reduce the frequency of maintenance cycles required to keep tools up and running.

We would like to thank all who stopped by our booth to discuss applications for EtchDefender™ as well as applications for our other temperature measurement and compression seal fittings. We will be following up with those people who discussed applications with us in the days and weeks ahead. For more information about EtchDefender™, click here.

Conax returns to SEMICON West with exclusive EtchDefender™ Technology

Visit us at Booth #5722
July 11-13, 2017

Longer TC life. Lower spend.

Visit us at SEMICON West Booth #5722 to learn about our patent-pending EtchDefender™ Technology. This exclusive coating extends the life of quartz thermocouple sheaths in ASM® EPSILON® epitaxial reactors up to 3 times longer to reduce your annual TC spend. Click here to preview our video and find out more.

Profile and Spike Thermocouples

We also offer standard or custom designed Profile and Spike Thermocouples for vertical and horizontal furnaces. Our thermocouples are high-precision temperature sensors, engineered to address the critical process temperature measurement and control required for the semiconductor, photovoltaic and LED industries. Talk to us about the wide range of thermocouple designs we manufacture for use on all the leading furnaces.

Pressure/Vacuum Feedthroughs

We are a leading source of pressure/vacuum feedthroughs. We offer various standard products and have the capability to custom design a solution for any application or equipment. We also specialize in HAST feedthroughs for reliability testing.

See us at Booth #5722 to find out more.

Pressure and Vacuum Sealing Assemblies

Conax Technologies manufactures a complete range of pressure and vacuum seal fitting assemblies to carry probes, sensors, wires, electrodes and other elements, satisfying diverse application requirements across a broad spectrum of industries.


  • Are used when probes and other elements must pass through a pressure or environmental boundary.
  • Maintain the integrity of the seal at the point of feedthrough penetration.
  • Employ “soft” sealant technology so that probes can be adjusted, removed and replaced yet are not deformed during installation.
  • Satisfy pressure, vacuum and environmental sealing applications in many industries—from process control and power generation to semiconductor fabrication and steel production.
  • Frequently reduce the overall cost of ownership, when compared with other sealing techniques, through reductions in installation time, downtime and the cost of replacement parts.
  • Unlike many conventional compression fittings or glands, Conax fittings can carry multiple elements (e.g., probes, wires, electrodes) in a single fitting assembly.

Upgrade in exhaust gas thermocouple sensors to be demonstrated at Texas trade show

Reduce maintenance time with improved replacement sensors

Our team will be in San Antonio, Texas on June 20th for the Frame 6 Users Group trade show to present a unique upgrade kit for Frame 6 turbines.

For older GE Frame turbines, we’ve improved replacement exhaust gas thermocouple sensors that fit older radiation shields. With this new kit, there’s no need for the entire thermocouple to be replaced. The upgrade kit provides a longer lasting sensor that also features lower maintenance time at change out and offers easier maintenance over the OEM products.

Cable assemblies that are purchased with this sensor may be custom manufactured to a desired length. Cables remain fixed in the turbine hot box and only the sensor needs to be removed. Cable assemblies are made from 18 AWG stranded conductors with PFA insulation and are jacketed with stainless steel over braid.

If you’re in San Antonio, stop by Booth #20 to check out a demonstration.

Our comprehensive solutions have been applied to many industries including Power Generation, Semiconductor, Oil & Gas, Aerospace, Pharmaceutical, Glass Production and others.

Conax is AS9100 certified meaning all products are manufactured according to the highest quality standards.

Last year’s trade show saw 586 exhibitors from 32 nations. We’re thrilled to join this year’s exhibit. Join Conax in Hall 1, Stand 1-635.


A Solution to Reduce Premature Failure in Standard Exhaust Gas Sensors

One small spring for a sensor.

One giant leap for sensor longevity.

Standard exhaust gas sensors in 7F and 9F class turbines are at risk of premature failure due to vibrations caused by gas flows, input vibrations and thermal expansion mismatch.

Conax has developed the solution

Conax Technologies’ patented Spring-Loaded Exhaust Gas Sensors have a high temperature compression spring that is inserted between two spacer tubes to dampen vibrations and keep the temperature sensor tip seated within the radiation shield.

Available exclusively from Conax

Conax’s Spring-Loaded Exhaust Gas Sensors are interchangeable with OEM parts and tested to OEM specifications.

When used in 7F and 9F class turbines, these sensors have proven to significantly increase sensor life and provide thousands of hours of field operation without failures. In addition, these exclusive Conax sensors:

  • Are interchangeable with OEM parts
  • Have been tested to OEM specifications
  • Significantly increase sensor life

Conax Technologies announces the acquisition of Arizona-based Quartz Engineering

Conax Technologies is pleased to announce the acquisition of Quartz Engineering, a manufacturer of quartz sheaths for temperature sensors headquartered in Tempe, AZ. S. K. Choi, former President of Quartz Engineering, will stay on and help with the integration of Quartz Engineering and Conax. Choi has 40 years of experience in the semiconductor segment of the quartz industry and 20 years of experience in the fabrication of the specific type of sheaths primarily used by Conax.

This acquisition represents a commitment to improving the company’s responsiveness and the quality of products the company can provide to customers in the semiconductor industry. Conax Business Unit Manager Michael Ferraro stated, “We’re expanding our focus in the growing Semiconductor industry. Many of the temperature sensors used inside process chambers need a semiconductor-grade quartz sheath to protect them from the chemicals and temperatures present. With the acquisition of Quartz Engineering, we now have in-house capabilities to design and manufacture quartz sheaths for temperature sensors.”

Ferraro explained, “By producing the sheaths in-house, we maintain greater control over quality and supply; and we can provide our customers with the solutions they need faster.”

Manufacturing operations will remain at the Tempe, AZ facility. Headquartered in Buffalo, NY, Conax Technologies is a designer and manufacturer of standard and custom engineered temperature sensors, compression seal fittings and feedthroughs, probes, sensors, wires, electrodes and fiber optic cables. The company has locations on the US west coast, as well as in Canada, Europe and Asia.
