Tunnel Series offers cooling capacities exceeding 100 W. Available in standard and custom configurations, the thermoelectric assemblies offer a compact form factor that fits inside analytical and medical instrumentation with tight space constraints. They use either air-to-air or direct-to-air heat transfer mechanisms designed with optimized thermoelectric modules (TEMs) for high efficiency. Other features include improved sealing to prevent moisture intrusion when running in dewpoint conditions and a reduced number of airflow paths required to operate more efficiently compared to traditional impingement-flow thermoelectric assemblies. When combined with the company’s SR-54 Series temperature controller, the assembly offers temperature control to within ±1°C.
