Further modifications are available on request, in addition to the basic types. We would be pleased to advise you on the exact options available for a specific element. Examples are:

According to RoHS directive requirements, serial thermoelectric coolers do not contain lead or any other forbidden materials. For the top stages an optimized thermoelectric material that allows us to reach the big value ΔТ with a smaller amount of stages is used. This makes it possible to produce multistage modules with optimal dimensions and low power consumption. We also offer thermoelectric coolers, installed or integrated in the standard — ТО (ТО3, ТО8 etc.), HHL, DIL, butterfly or special bodies.
