Way back in 1956, a group of scientists wanted to develop high-performance temperature sensors focused on rocket-engine testing for government research and military applications. With that goal in mind, Nanmac Corp. was formed.

Today, over 60 years later, the Holliston, Mass.-based company manufactures thermocouples and RTDs with accessories for measurement of thermal events up to 2300°C (4172°F) used in a variety of applications. The veteran-owned MTI associate member holds patents on temperature sensors, erosion gauges and multifunction sensors.

Nanmac serves the following industries: aerospace/defense, heat treatment/thermal processing, medical, OEM furnace manufacturing, oil and gas, petrochemical, pharmaceutical, power generation and semiconductor.

With the advent of newer material systems and requirements for better and more precise temperature controls under varying atmospheres, suppliers are now faced with the need to up their temperatures and process controls. Newer thermocouple materials and more robust sensors – along with the need to ensure you are running at the most optimum point – requires manufacturing excellence, material expertise and the very best calibration service support. Nanmac Engineering, which boasts more than 50 years of experience working at the leading edge of thermal technology, meets those requirements.

Nanmac works out of a 12,000-square-foot facility in Holliston, where all operations are set up as lean processes, reducing labor and increasing throughput. This has reduced turnaround from 10 days about 24 months ago to less than three days at present. The average employee has more than five years of experience at Nanmac. All employees are trained on new methods and assembly techniques, which leads to reduced scrap and less than 2% rework. The company has earned ISO 9001:2015 registration, and its calibration lab is accredited under ISO 17025 for direct comparison calibrations to 1700°C.

The company has had a busy year. Over the past 12 months, Nanmac has completed projects for:

  • Turbine testing at very high temperatures and in harsh environments using devices up to 2000°C and in wind conditions approaching Mach 0.6
  • Sintering processes at 1650°C for turbine blades, with control of temperatures to within +/-5°C
  • Rocket-nozzle testing and in-situ engine testing with very high speed TCs
  • A molten salt storage facility using various thermal devices, some of which were invented to meet the requirements

Nanmac is continuing to identify new materials (insulators for temperatures over 1700°C), better thermocouple elements and related thermocouple construction processes to optimize existing and evolving thermal sensing and measuring systems. Patented technologies in very dense thermocouples for use in medical and ultrahigh-temperature applications (12 TCs in a 1-inch sheath) are leading to continued developments that were initially only affordable for R&D and military applications. However, volume and performance are moving them rapidly into the commercial market, where the risk to the user is reduced considerably because the use data is developed under more extreme environments.
