Benchmark provides the semiconductor industry with a full compliment of thermal components with the following features:

  • Uniform or profiled heat throughout or in discrete zones.
  • Temperatures to 475 DegF (246 DegC).
  • Temperature control through thermocouples or imbedded thermostats.
  • Overtemperature protection through thermostats or thermal fuses.
  • Control of surface temperature by insulation provides operator safety.
  • Nylon coated snaps for operator protection.
  • Clean room compatibility.
  • Foam molded parts for precision fit.
  • Stock and custom configurations .
  • Agency approvals and conformance to UL, CE, and NEC 427.


With the above features, Benchmark Thermal holds a competitive advantage with...
Price. Never pay for quality you don’t receive. Continuous innovation into processes and materials keep Benchmark Thermal ahead of the competition in price and quality.

No amount of price reduction can compensate for poor performance. Benchmark Thermal has been manufacturing heaters since 1984 with high quality and low defect rates. Processes and controls meet the standards of ISO 9002 with traceability on key components.

When you want answers, there’s nothing worse than hearing “voice mail.” At Benchmark Thermal a real human is there to answer questions with the technical expertise to do the job. We have a fully staffed engineering department with the tools to craft any heater design.
