Out with the old and in with the new
Our client has three vertical Stal screws running their cold store (two run and one standby). With one beyond economic repair and the age of the two, a decision was made by the customer to renew all three compressors. In preparation for the removal of the 'non runner' we spent three weekends installing double block valves on all lines to all three machines. The lines are dry suction, discharge, liquid feed to the oil cooler, return from the oil cooler and the economiser. The first new compressor to be installed is a Sabroe 151.
