The Santa-Fe III Series Hydronic Air Handler with 13 Seer Cooling allows you to create a true hybrid system utilizing a boiler as the central heat source. In an integrated hybrid system a boiler is utilized as the heat source for all heating requirements, including radiant for hard surfaces such as tile, a loop of hot water baseboard or a ducted system for warm air via the air handler. The Santa-Fe can then be coupled with an A/C condensing unit to cool the structure. Since the boiler is being used as the heat source, various supporting equipment, including a Crown Boiler Mega-Stor or Maxi-Therm indirect water heater, can easily be integrated with this type of system. The Santa-Fe III Series with 13 Seer evaporator coil has capacities ranging from 1.5 to 5.0 Tons A/C. The multi-position cabinet can be used in upflow or horizontal installations. The Santa Fe III is also available as a heating only or cooling only unit.
