Nuremberg, with its walled inner city and wealth of German history, has an appeasing attraction to out of town visitors. For international visitors, Nuremberg is situated on an extensive network of rail, road and air connections to European cities and overseas destinations. With so many industry role players converging on

Chillventa— held every alternate year— it is often a time to renew old acquaintances and build new memories.

‘ Less energy input and less impact on the environment’ was a common focus of many exhibits throughout Chillventa; in particular, halls 5, 6, 7, 7a, 8 and 9, which focused on refrigeration, insulation and industry associations. Manufacturers of compressors, valves, controls and supermarket vending cabinets all had new products specifically for CO 2

, R290 or ammonia. One system used the most basic natural refrigerant: water( R718).

At the eurammon natural refrigerant forum, Bernd Kaltenbrunner, chair of eurammon, commented,“ At the first Chillventa in 2010, CO 2 was not prominent among exhibitors. Today, CO 2 as a natural refrigerant with zero ozone depleting potential [ ODP ] and a global warming potential [ GWP ] of only 1, is promoted throughout the show. Sourcing of components, compressors and all controls for subcritical or trans-critical CO 2 systems is no longer a problem.” Low GWP refrigerants were high on the promotion list by all of the refrigerant traders, and most were confident about the inclusion of HFCs in the Montreal Protocol( which has since been realised).

and techniques in recycling, recovery, reclaiming and leak detection were promoted alongside refrigerant and refrigerant cylinder management systems.

A-Gas set a new trend with their Gas- Trak Online( GTO) to track cylinders, calculate GWP, and report on refrigerant usage. The GTO is available as a web portal or a mobile app, providing realtime tracking of a fleet of cylinders in use by a team of service technicians. At a

click, a service manager can view the amount of refrigerant on hand and the monetary value tied up in cylinder deposits. Converting refrigerant leakages to global warming impact is easily done with the GWP calculator, which is part of the GTO.
