OptoTEC OTX/HTX Thermoelectric Coolers

Tark Thermal Solutions OptoTEC OTX/HTX Thermoelectric Coolers feature high-performing thermoelectric material that boosts performance and tightens process control. OptoTEC OTX coolers have a maximum operating temperature of +120°C, and the HTX coolers are designed to operate in temperatures up to +150°C. These coolers are primarily used in applications to stabilize the temperature of sensitive optical components in the telecom and photonics industries. Tark Thermal Solutions OptoTEC OTX/HTX Thermoelectric Coolers offer a miniature footprint, no sound or vibration, and reliable solid-state operation.
