Galaxy Steam models

High efficiency models, with intermittent pilot and vent damper, are also among the most efficient steam boilers you can buy. The Galaxy produces dry steam and delivers it to system through a 2 1/2" supply tapping. This ensures lower steam velocity and quieter system operation. The speed skimmer trough built into Galaxy “PZ” steam boilers, makes cleaning the boiler water easy by skimming of surface films of grease, oil and other contaminant's.

Low profile GXHA models

A built-in integral draft diverter on the four GXHA models reduce clearance requirements above the boiler to 18", making them ideal for use in locations with low chimney breaching or with overhead obstructions.
