TEC Thermoelectric Cooler Modules Wakefield-Vette TEC Thermoelectric Cooler Modules meet the requirements of higher currents and large cooling. The Peltier devices are sealed by white RTV silicone providing moisture protection, and feature 150mm standard wires. The long-term working temperature of the devices is recommended to be below +90°C, but the ambient temperature can arrive at +100°C. The TEC Thermoelectric Cooler Modules are often applied to experimental, scientific, and biomedical instruments, laboratory equipment, consumables, and industrial/electrical equipment.
