Multistage thermoelectric coolers

Applied in deep chilling systems, refrigerators with a large temperature difference, cooling systems for scientific and research.

Main fields of application:

freezers
thermostats
scientific and laboratory equipment
thermocalibrators
step coolers

Technological features:

For the top stages an optimized thermoelectric material that allows us to reach the big value dТ 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.

Abbreviations and definitions

TEC	thermoelectric cooler
TGM	thermoelectric generating module
DTmax	maximum achievable temperature difference between the hot and cold side of a thermoelectric cooler
Imax	input current through a thermoelectric cooler resulting in greatest DT (DTmax)
Umax	voltage on a thermoelectric cooler contacts at DTmax
Qmax	maximum cooling capacity of a thermoelectric cooler. It is determined at maximum current through a thermoelectric cooler and at zero temperature difference between hot and cold sides
Rac	electric resistance of a thermoelectric cooler measured at an alternating current with the frequency of 1 kHz
