The IOR's RACHP EngTech Section has been updating its catalog of good practice guides and bulletins. Our latest updates, listed below, are a source of practical "toolbox talk" style information for technicians:

Alternative Refrigerants for Existing HFC Systems (GN31)

Recovery of Refrigerant (GPG11)

Brazing Leak Free Connections (GPG32)

Refrigeration Piping for Oil Return (GPG35)

They will be of interest to technicians, service engineers, installers and maintenance experts. If you are a Technician or employ Technicians please pass this information on. 

Section members are sent new printed bulletins every quarter and IOR members can also download past publications for free from the IOR website. (Non members pay £6 per bulletin).   Membership of the section is just £42 per year and includes quarterly bulletins, immediate access to all downloads, and annual CPD certificate.   New members also receive a torque tool.  Find out more about joining at
