Forane® 123 Refrigerant

 

Technical Specifications

 

 

Forane® 123 is a single-component refrigerant with properties similar to R-11 that has one of the lowest ozone depletion potential values of all HCFCs. In addition, due to it's overall energy efficiency, Forane® 123 leads to an optimal total equivalent warming index.

 

Operating Considerations for New Systems

--------------------------------------------------------------------------------
Most new low-pressure centrifugal chillers are designed for use with Forane® 123. Most of the basic properties of Forane® 123 are close to those for R-11, including boiling point and vapor pressure, indicating that new Forane® 123 chillers should provide operating conditions and performance close to what has been seen with R-11 equipment. However, new equipment must take into consideration the differences in properties to optimize the performance of Forane® 123.

New chillers using Forane® 123 generally use the same lubricants as those for R-11. If installation procedures or service conditions call for addition of lubricant or replacement of components, please consult the equipment manufacturer for specific recommendations.

 

Retrofitting R-11 Systems

--------------------------------------------------------------------------------
When retrofitting R-11 chillers with Forane® 123, the differences in properties require that changes be made to controls, components, and/or the impeller drive train in order to minimize performance losses. Testing has shown reduced capacity and efficiency where the only modification was changing the refrigerant from R-11 to R-123. To obtain the maximum performance from Forane® 123, original equipment manufacturers offer recommendations, and in some cases, retrofit kits.

Forane® 123 is chemically compatible and miscible with the same lubricants used in R-11 equipment. Follow the manufacturer's recommendations regarding the choice of lubricants or procedure for oil changes during retrofit.

Forane® 123 is chemically stable in contact with common materials of construction. However, the refrigerant may affect the size, shape, or mechanical properties of plastics or elastomers present in R-11 chillers. Check each system carefully for any materials that will not be acceptable when Forane® 123 is introduced into the chiller. Obtain suitable replacement parts from the equipment manufacturer.

Some original equipment manufacturers (OEMs) may have different lubricant, safety, or retrofit requirements. Consult OEM guidelines for details.
