Thermal Wizard - Thermoelectric Assemblies Datasheet


Overview: SuperCool Series
The SAA-110-24-22 Air-to-Air thermoelectric assembly is a high performance thermoelectric based air conditioner. It is designed to temperature control small chambers used in medical diagnostics or sample storage compartments in analytical instrumentation. This unique, patent pending design offers a high performance hot side heat dissipation mechanism that convects heat more efficiently than conventional heat exchanger technologies. The design utilizes custom thermoelectric modules to maximize cooling capacity and premium grade fans to reduce noise. Moisture resistant insulation is used to keep condensation from penetrating into the TEM cavity. This unit operates at 24 VDC and is designed for indoor lab use environment. It has a maximum Qc of 100 Watts when ΔT = 0 and a maximum ΔT of 39 °C at Qc = 0.
