MackFri - 01c
MackFri® - 01c
ASHRAE Name : R-401c
(33% HCFC-22 / 52% HCFC-124 / 15% HFC-152a)
The Blends for replacement of R-12.
MackFri®-01c refrigerant. It is a zeotrope average pressure blend with temperature glide Dtgl = 4,5...5 К. Physical qualities of this blend are given in the table down. The refrigerant is intended for retrofit of operating on R12 refrigeration trucks. Thermodynamic and physical qualities of the refrigerant allow to fulfill effective and safe substitution of R12. At retrofit of the facilities operating on R12, before changing for MackFri®-01c refrigerant they substitute the filter-dehydrator and mineral oil for alkylbenzene.
