HFC - R507 Blends based on R-32, R-125, and R-134a, intended for use in low and medium temperature refrigeration. These blends are generally not supported by the equipment manufacturers and are not as popular because of the higher temperature glide and availability of other products. The main benefit is that these blends can be used to retrofit low temperature R-22 systems while significantly lowering the discharge temperaure. They require POE lubricants and any retrofit project must flush the existing oil. Part# Description Deposit 25R507 25 LB. CYLINDER $0 100R507 100 LB. RETURNABLE CYL. $125 1400R507 1,400 LB.
