Crown Santa-Fe is a new addition to our growing line of hot air equipment. The Santa-Fe air handler allows you to create a true hybrid system utilizing a boiler as the central heat source.

In many retrofit or new building construction applications, various types of heating are desired, such as radiant, baseboard, or warm air along with the need to provide cooling to the structure.

Utilizing separate equipment for each application is costly and requires more space than allotted for the various mechanical equipment.

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, driveway snow melt, a loop of hot water baseboard or a ducted system for warm air via the air handler. Versatility is unlimited.

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 an indirect water heater, pool or spa heater can easily be integrated with this type of system.

Another use for air handlers is to provide supplemental heat to a radiant system. There are several reasons why the contractor may want to provide supplemental heat. If a system is designed as an on/off system then it takes time to drive up the temperature in the slab. Using a two stage thermostat, the air handler will provide heat to make the space comfortable until the radiant has ramped up and can then take over.

Temperate days in the spring and fall provide another opportunity for this type of application. On temperate days when there are mild heat demands combined with solar gain to the structure, the space is prone to over heating. This is especially true in newer homes with a lot of glass. Again, utilizing a two-stage thermostat, the air handler can be used to take the chill out of the air without over heating the space and provide cooling to the structure when needed.

The Santa-Fe hydronic air handler is designed to provide for ultimate system flexibility and the slide out component design speeds installation and servicing.
