Multistage MS Series

With temperature differential up to 129ºC

The Multistage MS Series of thermoelectric coolers are able to reach colder temperatures than single stage thermoelectric coolers. It offers the highest temperature differential (ΔT), up to 129°C. This product line is available in numerous temperature differentials, heat pumping capacities and geometric shapes. The Multistage Series is designed for higher current and lower heat-pumping applications. It is ideal for applications operating in a room temperature environment. Custom designs are available upon request, however MOQ applies.
