Service distinguishes TGM from other component heater manufacturers Our focus is building a turnkey Sublimation Prevention System that is measured, designed, and field installed by our engineering team.

Pyewch® SPS patented technology sets a new benchmark for thermal safety, efficiency, and reliability.

Pyewch Concept
Pyewch® is a system of custom heated removable insulation jackets designed to meet your specific needs for controlled heat. Measured-Engineered-Installed, The Pyewch® system is a comprehensive turnkey solution

  • Pyewch® is unique, in that it senses and controls the pipe temperature
  • Our covers have a well-insulated core that is 'Cool to the Touch’
  • We use an ultra-clean silicone jacket that is durable
    and waterproof.
  • The low profile jumpers are constructed using military type connectors that are extremely rugged, and
    moisture resistant when mated.
  • Power indicator lights will immediately identify a problem.
  • Pyewch® efficient design operates on ultra-low power consumption.

Safety is an important part of the Pyewch® system
Your safety is important to us. That is why we have included as many safety features as possible and will continue to shape our product design around safety

  • Each heater jacket has built in over-temp protection to prevent any run away condition.
  • Each heater jacket has an integral ground plane over the heating element just in case a cover is accidentally cut or punctured.
  • GFCI (Ground Fault Circuit Interrupters) with 5mA trip are standard and built into our multi-zone control cabinets and cord set model is used with single zone units.
  • Pyewch® exterior surface temperatures are well below personnel protection standards and exceed the SEMI S2-93, ASTM C1055,
    and the US Navy MILSPEC-769 guidelines.

Gas Supply Lines
Certain gases used to convey dopants that are deposited on the
wafer surface require heat. Constant moisture free gas flow is important. Included in this category are SiH2Cl2, BCL3, C5F8, and WF6. These gas delivery lines are heated using electric heat trace and insulation.

We have found that controlling the temperature in incremental zones from the gas source to the mass flow valve in the tool produces the best results.
