Terry Young of J&E Hall will share his knowledge during an informal talk at this event.



Join us on the 4th December at this IOR Anniversary Networking Event in association with the London Refrigeration Society.  

On the 8th December 1899 the IOR was formed at a meeting chaired by R Leonard with 16 interested individuals. Initially known as the Cold Storage and Ice Association reflecting the early days of refrigeration in the UK, which was based on ice imports. 

This celebratory meeting will take place at the RAF Museum in Hendon. Meet fellow RACHP professionals and hear an informal talk exploring the history of the screw compressor.  

Before the presentation, those attending will have the opportunity to explore the Museum and discover the fascinating story of the RAF.  


In 1972 J & E Hall recognising the growing use of screw compressors began the design and development of their own screw compressor, using a concept of single main rotor plus two gate rotors. 

This talk describes the challenges encountered during the development process, from the first open drive prototype to decades later a compressor that encompasses innovations and advanced design features necessary to meet today’s shifting world of refrigeration.



  • Delegates will have until 15.30 to explore the museum. Click here to plan your visit.
