ThermoJet ES Precision Temperature Cycling System

FTS ThermoJet ES Precision Temperature Cycling System

ThermoJet Environment Simulator is a precision-controlled temperature forcing system that delivers an airstream of up to 20 SCFM to rapidly change the temperature of a product or Device Under Test (DUT).

ThermoJet provides temperature transition speeds unmatched in the industry, and can sustain air cooling temperatures of –80°C at 20 SCFM. It is made with the proven and reliable Dual Cool cascade refrigeration system and does not require complex and difficult blended gases.

The ThermoJet provides the smallest footprint for a floor model air stream temperature cycling system.

 

KEY FEATURES

  • Temperature range of +225°C to -80°C
  • High Temperature option of +375°C
  • Delivers 5 to 20 standard cubic feet of air/minute
  • Temperature transition from +200°C to -65°C in less than 15 seconds -80°C to +200°C in less than 15 seconds
  • Reliable and robust Dual Cool cascade refrigeration system does not require difficult blended gases
  • Small footprint allows maximization of space usage
  • External Device Under Test thermocouple for controlling temperature accuracy at the device
  • Configured with no holding arm, pneumatic arm or mechanical arm for easy air stream placement
  • Dry air purge to help protect test site
  • Selection of shrouds and boxes to meet your application
  • Built in air dryer with oil, water and particulate filters
  • Enhanced BTU/watt removal capabilities provided by higher air flow rate
  • Effortless change temperature and air flow set points

 

KEY BENEFITS

  • Significantly greater heat removal with up to 20 scfm air flow throughout temperature range
  • Decrease testing time with faster transition rates
  • Saves space with smallest footprint for floor model air streams
  • Less downtime and cost with superior, time tested, cascade refrigeration package and globally available, environmentally friendly and inexpensive refrigerants.
  • Avoid costly software conversion by utilizing universally compatible command set
  • Expand performance capabilities with optional thermal chambers.
  • Precise and reliable temperature control for device testing characterization
  • Thermally isolated environments provided by shrouds for precise temperature control
