Comparison list for the substitution of Russian Peltier modules     We can provide!   DEAR CUSTOMERS,   the recent developments in eastern europe add some extra pressure on the already tense supplying situation in the electronic industry. We at QUICK-OHM choose our sources and suppliers with great care, we audit all our partners frequently and we are fully convinced to provide the best possible product for a reasonable price. In the past we already qualified some alternatives to the well-known russian TE-companies and with this conversion table, we would like offer susbtitutes to the standard ranges of several manufaturers. Customized TECs can be offered on request, but most of the listed modules are available from stock and can replace the russian counterparts without any problems.     more information & the alternative list

Peltier modules or thermoelectric coolers (TEC) are basically thermoelectric heat pumps. It means that by supplying electrical energy, heat can be transported against its natural gradient, from one side of the peltier module where heat is absorbed to the other side, where heat is released. Thus, it is possible to use these peltier modules for heating or cooling applications. This behaviour is defined by the direction of the current. Theoretically, the temperature difference can go up to 73K for a simple element and up to over 100K for multi-level elements. In general, peltier modules are used wherever cooling with a small temperature difference, precise control and dynamic behaviour is necessary. The application of Peltier modules are very diverse, starting from complex analysis technology in the field of medicine to light-sensitive CCD sensors and mobile cooling applications.
