R-13B1

R-13B1

R-13B1 has properties that allow it work well in low temperature refrigeration systems with application temperatures from -40 F down to -60 F. R-13B1 is used in applications colder than R-22 while maintaining reasonable operating pressures, good capacity, and lower discharge temperatures in standard refrigeration equipment designs. In most cases, R-13B1 systems can be retrofitted to R-403B with adjustments in charge size, capillary tube length, and will result in lower suction pressures.

The evaporator will operate in a vacuum when the low side temperature is below -55°F. When existing R-13B1 systems are retrofit to R-403B, the capillary tube must be replaced with a longer/more restrictive size. The original lubricants can be used for R-403B, along with any additives the manufacturer may recommend.
