Using cylinders without high-level shutoff, overfill protection: a risk not worth taking.

Type of article: Article

Summary

With the increase in reclaiming CFC and HCFC refrigerant comes the danger of overfilling a re-usable refrigerant cylinder. 80% full is the maximum safe quantity of liquid that may be contained. Reliance on weight measurement cannot be safe when the liquid contained may be a mixture of refrigerant and an unknown quantity of oil which has a much lower density. The solution suggested is to fit all such cylinders with a float sensor and switch. This can be linked simply to the reclaim compressor drive to break circuit when the 80% level is reached. D.W.H.
