Ammonia Compressor Soft Start


Due to the continues on/off control on 30x350kW compressors to maintain certain set points on a refrigeration plant. Ceres Fruit Growers had to reduce their maximum demand and needed to look at ways to save electricity. By replacing old Star/Delta control panels with new and advanced Soft Starter technology, the maximum demand was reduced dramatically.

HmT Mechatronics got involved in this project at the end of 2012 and beginning of 2013. We replaced 2x 315kW Star/Delta control circuits with the latest SSW06 Soft Starter from WEG. The installation also included integration with the old compressor control panel via alarm signals like over pressure and fire sirens as well as shutdown and start-up procedures.
