To satisfy the increasing requirements of process industry for reactions at low temperatures, Polaris has developed a cryogenic units for rector cooling for temperatures as low as -100 °C. The process is based on cooling of an heat transfer fluid using liquid nitrogen as source of cold. The heat transfer is carried out on a special cryogenic heat exchanger designed by Polaris to obtain the best efficiency and solve the problem of temperature control unit and formation of solid organic ice.
In this case the combination of cooling and heating gave the customer a compact and integrated solution for an accurate control of the reactor in a wide range of temperature. Additionally the supply of the temperature control unit was integrated with the design and supply of the reactor itself for an highly engineered, but cost effective solution.
