From Laird Technologies, these SealTEC™ thermoelectric coolers provide maximum protection from water condensation when equipment is working at or below the 'dew point' or in humid conditions. The thermoelectric coolers prevent feature a SealTEC™ barrier that prevents water or gases from contacting elements and electrical conductors. The barrier is also effective for foam when used with thermal insulation techniques

Thermoelectric Modules - Peltier Effect

A range of semiconductor thermoelectric devices working on the Peltier effect. When supplied with a suitable electric current, they can either cool or heat. When subject to an externally applied temperature gradient these devices will generate a small amount of electrical power.The larger devices can be used for cooling or controlling the temperature of sub-assemblies. The small size of the mini module makes it ideally suited for cooling miniature electronic components such as infra-red detector chips, microwave IC's, fibre-optic lasers and detectors.,Alternatively, it may be used to minimise the effects of temperature coefficients on oscillator stability, reference voltages, amplifier offsets etc. by providing temperature control.
