Tornado Range
Maximise throughput without compromising accuracy
A range of chambers designed for accurate testing of substantial loads with minimal chamber footprint – ideal workhorses for a busy test laboratory.
Typical Applications
- Bulky and/or heavy loads (such as automotive and aerospace sub-assemblies or oil industry components)
- Test houses which need the flexibility to accommodate many kinds of loads under a variety of test conditions while controlling operating costs
- Temperature/humidity testing under fixed or cyclic conditions, satisfying numerous IEC 60068 test requirements plus a wide range of equivalent specifications
Advantages
High Performance even under Load
Tornado chambers are designed for demanding applications with heavy loads and/or high dissipation. In addition, the thermal plants are sized to perform under loaded conditions.AGREE versions available
The Tornado-V range is built to allow a Shaker table to be installed below the chamber floor to provide combined temperature and vibration testing.Interior sizes up to 5250ltrs
Single-frame construction up to interior volumes of 5250ltrs.Wide Temperature and Humidity Ranges
Temperature ranges of +180°C to either -40°C or -70°C are available and even +250°C with our Evaporator Protection feature. Liquid Nitrogen chambers are available with ranges up to +250°C to -100°C. Mechanically cooled chambers can be fitted with humidity covering all areas (10% to 98%RH, 10 to 100°C)ATEX interiors
Safe interior versions available with spark resistant impeller housings, temperature limited heater elements, Zener barriers on probes, etc.Suitable for Testing most Standards
Suitable for testing most environmental standards such as IEC 60068, etc.Custom Versions Available
As well as the standard range of Tornado chambers, our inhouse design and manufacturing (based in the UK) means we can produce custom versions, as required.SIMPLEtouch

Tornado Thermal Chambers
Choose from three different cooling mechanisms depending on your requirements.
Compressor Cooling
- Refrigerant gases in a closed-loop system are repeatedly compressed and expanded to cool the air in the chamber (same principle as domestic refrigerators)
- Maximum temperature = +180°C; minimum temperature = -70°C (multi-stage or cascade compression as standard)
- Temperature ramp rate = 2-15°C/min with load
- Offers reliable continuous operation with no ancillary services required
- Ideal for testing large or heavy loads with low to medium heat dissipation
Direct Liquid Nitrogen (LN2) Cooling
- Liquid nitrogen injected directly into the chamber to rapidly cool the interior
- Maximum temperature = +250°C; minimum temperature = -70°C
- Temperature ramp rates up to 30°C/min
- Requires continuous supply of LN2 and safe venting of nitrogen gas during operation
- Can cope with greater heat output from components under test than compressor cooling
- Ideal for thermal stressing and accelerated life testing
- Caution – reduced oxygen levels can occur inside the chamber
Forced Ambient Air Cooling
- Range of heat-only chambers (ovens) with same dimensions and volumes as ranges above (model numbering TC Tornado 800 600 800, etc)
- Controlled cooling to avoid thermal shocking of components under test
- Maximum temperature = +250°C; minimum temperature = ambient + 20°C
Tornado Environmental Chambers
Combine temperature cycling with precise control of the relative humidity.
- Same cooling mechanism as compressor-cooled thermal chambers
- Maximum temperature = +180°C; minimum temperatures = -70°C (multi-stage or cascade compression)
- Water vapour added to air from heated water bath and removed through condensation on cooled copper coil
- As standard, achieves humidity conditions within region A in chart below; can be modified to meet regions B and C if required (amend model number to TH(AB)C/TH(AC)C/TH(ABC)C as appropriate)
Humidity – Standard Operating Regions
A – Typical region of humidity control in chambers
B / C – Optional regions for specialised applications
