R123 is a HCFC, which replaced R11 in low pressure centrifugal chillers. It is being phased out due to its high ozone depleting potential.
Product Features and Benefits
- R123 equipment has been engineered with the correct materials of construction and sized properly for the intended job
- Retrofitting existing R11 chillers to R123 may require replacement of seals, gaskets, and other system components to obtain the correct operation conditions and prevent leaks
- The ASHRAE safety rating for R123 is B, which indicates that lower levels for personal exposure are allowed in normal daily operation and service conditions
- Extra Precautions and machinery room requirements must be observed (specific requirements are spelled out in the ASHRAE Standard 15, Safety Code for Mechanical Refrigeration)
