D.A.T.E. (Developpement Et Application Des Techniques De L Energie) designs and manufactures custom heat exchangers and thermal management systems for extreme environments. The company manufactures plate heat exchangers for liquid-to-liquid, gas-to-liquid, and liquid-to-gas thermal transfer applications. It also produces brazed aluminum exchangers optimized for gas-to-gas applications, as well as fin-and-tube heat exchangers for compact thermal transfer in constrained spaces. Additionally, the company manufactures cryogenic heat exchangers for ultra-low temperature applications, including sub-Kelvin environments used in quantum computing systems. It also provides integrated thermal management turn-key systems that combine air coolers, hydraulic circulators, and thermal modules. The company carries out engineering, modeling, design, fabrication, testing, and validation of custom-engineered thermal solutions, and its manufacturing capabilities include welding, brazing, adhesive bonding, sheet metal work, and assembly and wiring operations across stainless steel, aluminum, and copper materials. The company supplies thermal solutions for fighter aircraft, ground-based and airborne radar systems, frigates, submarines, and satellite test chambers. It also supplies thermal solutions for particle accelerators, high-energy physics research facilities, quantum computing systems, aerospace and space systems, high-density data centers, cryogenic liquid systems, and liquid hydrogen applications. It serves defense, aerospace, scientific research, and industrial technology customers. D.A.T.E. (Developpement Et Application Des Techniques De L Energie) was incorporated in 1978 and is based in La Motte-D'Aveillans, France. D.A.T.E. (Developpement Et Application Des Techniques De L Energie) operates as a subsidiary of DOPAMINE.
