J & E HALL LIMITED

The ammonia-based system is at the heart of the Victorian plant in Wiltshire. Brewery chiefs turned to J & E Hall's expertise after deciding it made economic sense to replace an old ammonia-based system.

The new equipment serves a transfer beer chiller, a cask conditioning room, three cold rooms as well as several condition tanks involved in the cask conditioning and refining processes where temperature levels are key. It was out with the old and in with the new for a HallScrew HSO 3221 on fixed speed with slide valve control and HSO 3216 on a variable speed drive, running between 1250 rpm and 2500 rpm to match the production loads.

J & E Hall Fridgewatch controllers were used to control the new compressors and the inverter. These were connected to new control panels which were manufactured and installed within the project. The existing evaporator and condenser set-up was kept.
