Thermoelectric Assemblies TEC Assembly Series Air to Air Thermoelectric Cooler Assemblies Wakefield- Vettes TEC Assembly series of Air to Air Thermoelectric Cooler Assemblies are usually used to cool (or heat) objects in enclosures. Heat is absorbed and dissipated by heat exchangers equipped with fans. To install, simply cut a hole, plug in the assembly and connect it to a power source. Our coolers are compact and dependable. All models are optimized for T and efficiency. A variety of voltage options from 12 to 48 volts and cooling capacity from 15 watts to 200 watts are available, Typical applications include cooling electronics cabinets, analytical instruments, commercial refrigeration, food transportation boxes and small electronics enclosures.
