An Update on R-22 Retrofits
Stephen Spletzer, Arkema
Napa Room C
R-22 is being phased out under the Montreal Protocol. ln order to sustain the installed R-22
base and provide quality service, technicians must be able to navigate the many, and
sometimes conflicting refrigerant claims to find appropriate solutions. This session will promote
responsible retrofit selection by exploring the gamut of issues that should be addressed before
a retrofit can begin. Particular emphasis will be placed on best work practices and dispelling
some of the many refrigerant misconceptions that exist in our industry today. Attendees should
be able to make an informed selection when choosing an R-22 retrofit, as a result of this class.
Instructors should also be able to pass along this information to their students.
