Control and instrumentation
- Control
- Watlow F4T controller with Hanse ChamberCore software: programmable temperature ramps and closed-loop cascade control of the product temperature, over Ethernet
- ChamberDAQ
- 24 universal inputs on each Watlow F4T (thermocouple, RTD, mA, mV/V), with more F4Ts for more inputs, plus up to eight WebDAQ modules for 128 external thermocouple channels
Safety
- Door interlocks
- Opening a door shuts off system operation
- Emergency power off
- EPO shuts off system operation
- Over/under limit
- FM-approved, with its own sensor in the air stream
- Interlocks
- Heaters and LN2 interlocked to the fans; three-phase supply monitored for phase loss and balance
- Electrical code
- Built to NEC code with UL / CE marked components
Options
- Extended temperature — down to −150 °C and up to +400 °C, as an option or custom build.
- Humidity — direct water injection, 10 to 85% RH from 25 to 65 °C, with a capacitance sensor.
- More thermocouples — 14 more, for 16 monitored in all.
- Floor plug — an insulated plug that reduces the working volume.
- Anti-condensate heaters — for the door, windows and outer surfaces.
- LN2 system — complete installation, piping and controls.
- Vibration — add a standalone 6-DoF vibration table, or choose the VTC-25 HALT/HASS chamber.
Warranty and support
- 1-year equipment warranty from shipment: parts and labor for the first 90 days, then parts at no cost other than travel.
- Supported for the long term — including controller retrofits for older systems.
- Built in Allegan, Michigan — designed, fabricated and supported in the US since 1993.
