The stable, responsive temperature control system of choice for fluids characterization
The ARES Advanced Peltier Control System (APS) is the best temperature control device for liquids, offering unmatched accuracy through precise, direct temperature measurement at the sample. The APS is compatible with a wide range of fixtures, including parallel plate, cone in plate, and concentric cylinder configurations. Additional quick-change plates come in a variety of sizes, surface finishes, and materials. Compatibility with other accessories and easy Smart Swap TM mounting empowers users with temperature control without sacrificing broader applications.
The APS is a Smart Swap Peltier temperature controlled environmental system with a temperature range of -10 to 150 °C, with a maximum heating rate of 20°C/min and a temperature accuracy of +/- 0.1 °C. Unlike some Peltier temperature systems, the APS can accommodate parallel plate, cone and plate, and concentric cylinder configurations meet a wide range of demanding applications. The new quick-change lower plate comes standard with a 60 mm diameter hardened chromium surface and a unique bayonet fixture that allows the user to quickly and easily adapt the plate surfaces to crosshatched or sandblasted finishes. The APS also features an efficient solvent trap cover for blocking evaporation during testing of volatile materials.
Technology
The Advanced Peltier System, equipped with an array of multiple Peltier elements, controls temperature through a non-contact heat transfer mechanism. A 50 μm gap between the Peltier elements and the system core allows for the most pure sample deformation while allowing efficient heat transfer across the thin gap. Temperature measurements are made using PRTs placed in intimate contact with the center of the lower plate or cup. The temperature signal is transmitted to Printed Circuit Boards, from which the temperature reading is transferred through a non-contact (wireless) mechanism to secondary boards in the motor. These temperature readings enable direct control the temperature, resulting in accurate and responsive temperature control.
Cone & Parallel Plate Geometries
Several upper geometry types are available based on the needs of the test at hand. Heat break collars reduce heat transfer and improve temperature uniformity while maintaining the ruggedness and chemical resistance of a stainless steel plate. Low expansion and low thermal conductivity polyphenyl sulfone (PPS) plates further improve temperature uniformity.
Plate Surface Textures
Both upper geometries and lower quick change plates are available with a range of surface textures. Roughened surfaces effectively eliminate slip, an artifact which can occur with many materials, particularly filled systems.
Quick Change Plates
The APS features a Quick Change Plate system that allows several lower plate covers to be easily attached using a simple bayonet-style locking ring. These plates can be selected based on material, diameter, and surface finish. Disposable plates are also available for curing materials.
