There are many applications of industrial lasers. Whether used for cutting, welding, micro-machining, additive manufacturing or drilling, industrial lasers generate a significant amount of heat that can affect accuracy and repeatability of the system. Efficiently cooling lasers ensures proper, long-term performance of the laser. Compressor-based refrigeration systems have long been used to cool laser systems, while thermoelectric-based chillers or coolers offer spot cooling for low power lasers and optical components. Larger systems greater than 500W typically require an external compressor-based chiller while systems smaller than 500W use a thermoelectric based chiller or thermoelectric coolers.
Nextreme Recirculating Chillers
Compressor-based refrigeration systems are traditionally used in industrial laser applications because of their high coefficient of performance (COP). Laird Thermal Systems’ Nextreme Recirculating Chiller Series delivers reliable and precise temperature control for industrial laser systems. The chiller utilizes high-performance variable speed motors for low noise operation and reduces energy consumption by up to 50% compared to conventional compressor-based systems.
UltraTEC™ UTX Thermoelectric Coolers
Laird Thermal Systems UltraTEC UTX Series is a high performance thermoelectric cooler used for applications in industrial lasers and optics where high heat pumping capacity is required in a small surface area. The UltraTEC UTX Series features a higher thermal insulating barrier that creates a greater temperature differential compared to standard thermoelectric coolers. Assembled with advanced thermoelectric materials, the UTX Series of thermoelectric coolers offers a 10% boost in heat pumping capacity.
