Liquid Series LA-075-24-02
MFG Part Number: LA-075-24-02-00-00
Liquid Series Thermoelectric Cooler Assembly
The LA-075-24-02 thermoelectric cooler assembly offers dependable, compact performance by cooling objects via liquid to transfer heat. Heat is absorbed through a liquid heat exchanger and dissipated thru a high density heat sink equipped with an air ducted shroud and brand name fan. The thermoelectric modules are custom designed to achieve a high coefficient of performance (COP) to minimize power consumption. It has a maximum Qc of 71 Watts when ΔT = 0 and a maximum ΔT of 42 °C at Qc = 0. The liquid heat exchanger is designed to accommodate distilled water with glycol. Corrosion resistant turbulators are enclosed inside channels to increase heat transfer. Mating port adaptors are sold separately.
Features
  • Compact design
  • Precise temperature control
  • Reliable solid-state operation
  • DC operation
  • RoHS-compliant
