Economisers

For improved efficiency

WITT economizers are used to improve the efficiency of screw compressors. By using an economizer, the amount of flash gas at the low-pressure level is reduced. This often allows for the selection of a smaller compressor and separator, significantly increasing overall system efficiency. Thanks to their simple construction and mechanical operation, WITT economizers are highly reliable and  maintenance-free.
