    In many situations, the object being cooled generates little or no heat. In these cases, the combination of TE cooling and thermal insulation produces large temperature differences. For a hot side around room temperature, temperature differences of about 72°C and 125°C can be achieved by single-stage and multi-stage TECs, respectively.

    2015-2-4 · Unlike pure viscous- or elastic-based materials, Sorbothane reduces vibrations over millions of cycles without degrading. Because it’s a visco-elastic material, it absorbs, isolates, and reduces vibrations simultaneously. It is capable of absorbing nearly 95% of shock energy and reducing more than 50% of vibration energy.
