PowerCycling PCX Thermoelectric Coolers

Tark Thermal Solutions PowerCycling PCX Thermoelectric Coolers are tested to withstand rigorous cycle testing based on the latest PCR industry test protocols. Thermal cycling exposes thermoelectric coolers to mechanical stresses as the module expands and contracts from repeated heating and cooling cycles. This stressful process can quickly degrade the long-term performance and operational life of a standard thermoelectric cooler. These Tark PowerCycling PCX Thermoelectric Coolers are assembled with next-generation thermoelectric materials and enhanced module construction, providing improved performance and long-life operating in thermal cycling applications.
