Elastomeric Seal Changes Required:
Minimize Potential for Leaks
HFC refrigerants cause seals to swell at a different rate
than HCFC/CFC refrigerants

Minimal Control Adjustments
Evaporator and condenser pressures are similar to R-22.
No set point changes are needed during the retrofit; however, some minor
adjustments may be necessary to optimize system performance after the
retrofit.

•Hourly energy consumption of ISCEON® MO99 was statistically the
same as R-22 within the variability of the data
•Suction and discharge pressures of ISCEON® MO99 were similar to
R-22.
•Minimal control setting changes were required
•Use of liquid subcooling improved ISCEON® MO99 energy
performance
•Case temperatures with ISCEON® MO99 were similar to case
temperatures with R-22
