Thermoelectric Modules & Systems

Presently companies worldwide demand compact, noiseless and reliable systems for industrial cooling and temperature control. Thermo Electric Coolers (TEC) meet all of the mentioned requirements. Typical TEC consists of thermocouples connected electrically in series and sandwiched between two alumina ceramic plates. The number of thermocouples may vary. This makes it possible to construct a TEC of a desirable cooling capacity ranging from a fraction of a Watt to hundreds of Watts. When the constant electrical current passes through the thermoelectric module the temperature difference is generated between its sides – one (cold) side is cooled, another (hot) side is heated. If efficient heat withdrawal is provided for on TEC hot side, for example, by heat sink, the temperature can be obtained on its cold side being by tens of degrees below the ambient temperature. Shyam International is sole distributor for India for Thermo Electric Coolers and related systems produced by Kryotherm, Russia. At present TECs are widely used in such high technology fields as telecommunications, electronics, space, medicine, etc. TECs are also used in such consumer goods as portable refrigerators, freezers, water coolers, wine cabinets and beer coolers, compact air conditioners etc. These are available in single stage or multi stage coolers depending on cooling requirements. Main benefits of TECs are: environmental safety, low-noise operation, maintenance free and saves energy in considerable level.
