1) HFC-23 is used as refrigerant, sometimes as a replacement for CFC-13.
2) It’s used in semiconductor industry, in plasma etching of silicon oxide and silicon nitride.
3) It’s used as a total flooding fire extinguishing agent.
4) It’s used in very low temperature refrigeration systems, typically on the low stage of multi-stage systems. R-23 has properties similar to R-13 and can be used as replacement R-13 in existing systems. R-23 has higher discharge temperatures than R-13, that’s why this gas should be used to equipments without temperature working limits. Polyester (POE) lubricants should be used to charge hydrocarbon oil additives to ensure proper oil return.
