Multistage thermoelectric coolers

2-stage thermoelectric coolers, Peltier elementsApplied in deep chilling systems, refrigerators with a large temperature difference, cooling systems for scientific, research and special devices. Also used for cooling infrared photodetectors, X-ray detectors, etc.

Main fields of application:

  • CCD-matrix and infrared photodetectors cooling
  • cold cells and freezers
  • thermostats
  • scientific and laboratory equipment
  • thermocalibrators
  • step coolers
  • different coolers and thermostabilizers of detectors
  • night vision equipment

Technological features: 3-stage thermoelectric coolers, Peltier elements

For the top stages an optimized thermoelectric material that allows us to reach the big value ?Т 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
