SQD series

Dry expansion evaporator

The dry expansion evaporators from the SQD series have been developed for air conditioning and process cooling applications. Their unique square design enables high heat transfer performance while making efficient use of the available installation space. Thanks to the patented tube bundle and optimised internal design, they are ideally suited for liquid chillers with medium to high efficiency.
