Multistage thermoelectric coolers

Terms and conditions of sale

Ecogen's multistage thermoelectric cooling modules are used if a single-stage module cannot provide the required temperature difference of more than 70K. Ecogen has developed and serially produces multistage Peltier cooling modules with up to five stages. Each subsequent stage increases the temperature difference, but also increases the consumption of electrical power. This leads to a relative decrease in refrigeration capacity and efficiency with an increase in the number of cascades.
