MackFri® - 507

MackFri® - 507
ASHRAE Name : R-507
(50% HFC-125 / 50% HFC-143a)

The Blends for replacement of R-502 and HCFC's.

MackFri®-507 refrigerant.. Blend composition: R125 and R143a are correspondingly 50 and 50 % according to their mass. Boiling point is -46,7 oС. Molecular mass is 98,86 gm/mole. Ozone depletion potential ODP = О, global warming potential GWP = 3900. The refrigerant has been developed for retrofit of the low-temperature refrigeration systems operating on R502 and for charging of the new equipment in combination with the use of polyester oils. Characteristics of MackFri® refrigerant are given below.

Packing: 11.0 Kg. (25 lb.) Net nonrefillable Steel cylinders and individual neutral carton outside.
