1994 Krack 130 Ton Blast Freezer Coils, removed from IJ White Spiral Freezer, Model: S1.5/334-8810-232-RBA-HGU/WD-LH. Suction temp: -40F, Room temp: -26F,TR: 130,airflow: 210,00 cfm, FPI: 2 / 3,coil rows: 4 / 6,op. wt. 222937, not included were 8 10 hp fans, were being supplied ammonia from a 250 hp high stage screw with +20F suction and 95F condensing and a 200 hp booster with -40F suction and 20F condensing. The coils are in very good condition with no rust on the coils or fins, the staining you see on the fins came from rusty bolts that dripped water from a Frame behind the coils and that rusty water was pulled though the coils, we think that it might clean up which we will try to do once the coils arrive in our yard
