- Effective and convenient heating and cooling
- Air cooled Peltier hood and plate; sustainable and cost efficient
- Temperature control with minimized temperature gradients from -50 °C to +220 °C
- Modular system for combination with rheo-optics accessories
- For cone-plate, parallel-plate, and cylinder measuring systems
Peltier temperature control systems are ideal for applications such as lubricants, paints, cosmetics, foods, hot melts, and even polymer melts. Based on counter-cooling with a fluid circulator or only air, the systems are capable of high heating and cooling rates and excellent temperature accuracy. Each one of the different models is easily integrated, exchanged, and operated, due to patented features, such as Toolmaster, which automatically recognizes and configures all connected devices.
Key features
Plate systems for configurations with one drive
Peltier temperature devices for cone-plate and parallel-plate geometries offer fast and accurate temperature control. With the widest temperature range on the market (270 °C), they’re ready for temperatures between -50 °C and +220 °C. With the air-cooled version – which uses CoolPeltier technology – the range is -10 °C to +220 °C. An optional hood is available, which reduces temperature gradients to ≤0.1 °C, enabling measurements according to AASHTO T315 and other international bitumen standards. The hood’s unique design, with built-in LEDs, illuminates the measurement area and enables 360° trimming of your sample. Replacing each of the more than 30 different screw-on plates takes less than five seconds, so that using the right surface or material for your application is easier than ever before. Each Peltier device comes with the patented Toolmaster technology, which automatically recognizes measuring systems and supports plug-and-play installation in less than a minute.
Cylinder systems for configurations with one drive
The Peltier temperature devices for cylinders comprise an innovative heat transfer system for fast and accurate temperature control from -30 °C to +200 °C when working with fluid circulator counter-cooling, or from 0 °C to +180 °C using the air-counter-cooled device. These devices are dedicated for use with concentric cylinder and double-gap measuring systems. In addition, a Peltier temperature device is available which can be combined with pressure cells to measure in a closed environment or under increased pressure.
Cylinder and plate systems for configurations with two drives
For rheometer configurations using two rotational drives, a specialized Peltier temperature device ensures precise temperature control across a range of -20 °C to +180 °C for cone-plate and parallel-plate systems, and -20 °C to +150 °C for concentric-cylinder and double-gap measuring systems. This setup supports measurements in both separate motor transducer mode and counter-movement mode, and features a thermally coupled hood to ensure the lowest temperature gradients within the sample. The lower measuring systems include a temperature sensor near the sample that enables accurate determination of the true sample temperature.
Ready for advanced material characterization
In addition to the standard Peltier temperature devices, Anton Paar offers modular Peltier systems that can be combined with rheo microscopes, a small-angle light-scattering system, a polarized imaging option, a Raman or dielectric spectrometer, or self-designed optical accessories. This provides information on the smallest microstructure changes in the sample. The macroscopic “big picture” can be determined with simultaneous rheological measurements. The temperature control unit, suitable for covering a temperature range from -20 °C to +200 °C, can also be combined with a UV light option to perform rheological characterization of UV-reactive samples.
Additional accessories and solutions
In addition to standard models, devices with disposable measuring systems and application-specific surfaces are available to meet even sophisticated measuring demands (e.g., to prevent wall slip or characterize curing reactions). The Peltier temperature device can be combined with solvent traps to prevent evaporation and drying of the sample (for coatings, paints, and food rheology), or an immersion option to characterize the sample in a fluid environment.
A patented (AT525.752 B1) passive temperature device is also available. This provides precise temperature control by generating convection, minimizing temperature gradients in the range from 0 °C to 50 °C without the use of active Peltier elements.
