Horizontal compressors for pressurised LPG and NH3 transfers

Horizontal compressors are used for transfers of liquefied gas from one vessel to another by forcing the media through a pressure increase in the gas phase with following vapour recovery to maximise the transferred volume. They are used in bulk transfers, barge and rail loading and unloading, pressure boosting and many more.

Horizontal compressor

Product description

As the capacity of a vertical compressor may not always be sufficient for all tasks, the horizontal compressor is the ultimate alternative as it provides the largest liquid transfer capacity.
