“There is a sense of momentum when it comes to naturals,” said Marc Chasserot, managing director,Shecco, who moderated the two-day event. “There is something happening here.” And while much of the conference featured case histories of ongoing refrigeration projects involving natural refrigerants, Chasserot acknowledged that a major impact will only come when many more end users and service contractors see that there is a cost-effectiveness and energy-efficiency distinctive compared with f-gas refrigerants most commonly in use.
