Isophase Bus Duct Cooling Coils

Engineered Cooling for Ducts & Power Cables
Isophase (isolated-phase) Bus Duct Coolers circulate dry air through the main bus to cool the phase conductors, which can nearly double the ratings of the same conductors when used in a self-cooled system. The cooling air is recirculated across the cooling coil, which maintains the bus at its optimum operating temperature. These cooling systems typically are non-safety related. SRC’s engineers use their expertise to match fit and function of existing equipment or to add enhancements as needed inside the air handler’s unit.
