Air-cooled screw chiller

New chillers for Arla dairy processing plant


Processing of milk products requires the correctly designed process in order to attain end products of the highest quality. Processing of milk involves pasteurization, a technique that destroys pathogens in milk and makes it safe to drink. Pasteurization necessitates the use of chilled water to cool down the milk after the heating-up process to prevent the deterioration. During the cooling process, the pasteurized milk has to be cooled to 0°C. Thus, the production of chilled water for dairy processing operations is a vital part of producing safe and high-quality consumer products. Tight thermal control is also a crucial requirement for dairy processing facilities.

V-shaped microchannel coils for chiller applications


The efficiency of air-cooled chiller is dictated by the condensing temperature, which may be decreased with increasing heat transfer performance of the condensing coil. Microchannel heat exchangers have become popular in chiller applications due to better thermo-hydraulic characteristics in comparison to conventional finned tube heat exchanger designs. The most straightforward way to improve heat exchanger performance is to increase its face area by combining two microchannel coils in V form.
