The LL-120-24-00 thermoelectric cooler assembly offers dependable, compact performance by cooling objects via liquid to transfer heat. Heat is absorbed through one liquid heat exchanger and dissipated thru a second liquid heat exchanger. The thermoelectric modules are custom designed to achieve a high coefficient of performance (COP) to minimize power consumption. It has a maximum Qc of 122 Watts when ΔT = 0 and a maximum ΔT of 42 °C at Qc = 0. Heat exchangers are designed to accommodate distilled water with glycol. Corrosion resistant turbulators are enclosed inside channels to increase heat transfer. Mating port adaptors are sold separately.
- Compact design
- Precise temperature control
- Reliable solid-state operation
- DC operation
- RoHS-compliant
