COMPRESSORS As one 565kW HallScrew compressor is the equivalent to six
reciprocating types, for this project, it meant we could use just four compressors; 24, 90kW reciprocating compressors would have been needed to achieve the same results. Overall, this led to reduced installation complexity, including the number of components – and things that can go wrong. With only three to install and maintain. Balanced compression, due to the main rotor which meshes the two diametrically opposed star wheels, means main bearing life is extremely long – over 100,000 hours – which leads to reduced lifecycle costs. A robust single piece casing enhances this simplicity and longevity.

Upgrade and save clear, including savings which make a return- on-investment swift, there is no place for outdated cooling; a false economy that will hamper the path to Net Zero and the success of any organisation sticking with old-fashioned systems that do not deliver
Compressor upgrade in action: Makios Logistics is one of the largest
logistics companies in Greece, handling a wide-range of goods, including chilled food products.
At its site in Thessaloniki port, Makios
required a total upgrade of its Freon refrigerant system. Freon, or R22, has been phased out due to its high Global Warming Potential (GWP). Apart from having poor environmental credentials, the old system threat due to their forever chemical constituents. J & E Hall was called upon
to provide new compressors for the system upgrade, a

refrigerant solution, both the running costs and sustainability have been
dramatically improved.
