Designed for demanding applications, especially where testing large or heavy products. Powerful airflow ensures good thermal tracking of products under test and the strengthened versions can take several tonnes of load. There are even versions for AGREE styled testing – combined temperature and vibration.

Tornado chambers are available in a wide range of Temperature and/or Humidity ranges as well as internal sizes. Integral or remote cooling plants are available.

Temperature/Humidity Testing

Tornado chambers are designed for large or heavy loads and are suitable for both Thermal Stress and temperature/humidity cycling applications. Special attention has been given to achieving a high, front-to-rear air-flow. This ensures consistent conditions throughout the chamber volume and therefore more meaningful test results.

The Heating/Cooling Plant on the Tornado chambers is sized to suit each requirement and can vary from 1 to 10°C/min (and higher with LN2boost). Standard chambers are available with two temperature ranges, using single stage (-40ºC) or cascade (-70ºC) cooling plant, and a maximum temperature of +180ºC. Remote or water-cooled plant can be specified to minimise heat and noise in the test area.

The SIMPLEtouch touch-screen programmer makes it easy to set-up and monitor the chamber conditions, and is particularly useful for simplifying the programming of complex cycles.The chambers are attractively styled to blend in with modern production and laboratory equipment and a wide range of sizes are available.

Typical Applications

  • Thermal Stress testing
  • Temperature/Humidity Testing
  • Testing of Materials, Components and Assemblies
  • Electronics, Automotive and Aerospace
Custom chambers and options

Sharetree are able to offer cost effective custom chambers and options where standard solutions are unsuitable, via our in-house manufacturing capabilities. We have many chamber variations and options in our design library that are not shown as standard options.

Sharetree has extensive experience of providing complete test systems and will be pleased to discuss specific product interfacing and testing requirements.

Humidity control

The Tornado chambers are designed to accept a wide range of humidity control options to enable a variety of steady state and cyclic damp heat tests to be performed.

Close control of temperature/humidity conditions is achieved by means of an electronic microprocessor controlled dual loop programmer. An electronic capacitive humidity probe is fitted as standard for high reliability and minimum maintenance.

Humidity generation requires a supply of de-ionised water. This may be supplied from a local reservoir or automatically from a mains supply, where available, via an optional de-ioniser unit. Chamber condensate is normally re-circulated to minimise water consumption, but may be drained at programmable intervals if required.

Construction

The inner chamber is fabricated from high grade stainless steel for corrosion resistance and easy cleaning. All internal joints are seam welded to ensure a vapour tight construction. The mild steel outer cabinet is attractively styled and has an easy to clean epoxy paint finish.

Dense mineral wool insulation blankets the entire chamber to ensure energy efficient operation.

Full access to the interior is gained through the hinged front door. This has a double sealing arrangement, pressurised by the door catch, to prevent moisture ingress at low temperatures.

Powerful fan(s) are used to ensure low thermal gradients and uniform testing of products. The fan motors are mounted outside the chamber for maximum reliability.

The refrigeration plant consists of a single stage or cascade system (depending on temperature range), and is generously sized for long term reliability. Anti-vibration mounts and vibration eliminators minimise noise and vibration.

Remote plant and water cooled compressors are available as options.

SIMPLEtouch programmer

All Cyclone chambers now come with our latest SIMPLEtouch touch-screen programmer at no extra cost. The Sharetree SIMPLEtouch Chamber Programmer enables the temperature (and humidity where fitted) to be easily programmed and displayed on Sharetree test chambers.

The touch-screen window gives a clear, user-friendly interface with a constantly updated display of the current set and actual values for temperature and humidity*.

SIMPLEtouch uses only commercially available components to ensure low cost of ownership over the lifetime of the chamber.

Combined Temperature/Vibration Test chambers

Tornado-V AGREE* style test chambers are temperature cycling chambers with a removable floor. This enables a vertical shaker to be installed below the floor, with the armature protruding through the floor, allowing the product to be vibrated during temperature cycling.

The vibrator and floor are sealed during operation to minimise heat losses, but can be removed for maintenance, or replaced by a solid floor for temperature-only testing.

*Advisory Group on Reliability of Electronic Equipment

Tornado-V Customising

The test chamber heating and cooling plant can be optimised for a specific test load.

Single-stage (-40⁰C) and cascade (–70⁰C) plant can be sized to give the required temperature ramp rate for a specific thermal load. Remote plant and/or condensers can be used to keep heat and noise away from the test area.

Optional features

  • Alternative temperature ranges and ramp rates available
  • Multi-glazed heated window
  • Internal lighting
  • Product Protection thermostat
  • Cable ports
