VHBXB-HW Series VARIABLE SPEED HOT WATER/DX AIR HANDLERS ON ENTIRE UNIT

The addition of variable speed drive affords increased efficiency, higher humidity control, and quiet operation. The variable speed drive slowly “ramps up” when the unit is turned on and “ramps down” when the unit is turned off. Variable speed operation is approximately 20% more efficient than constant speed operation. These units are for Upflow and Horizontal application. Not for conterflow use.

Aqua-Therm fan/coil units provide the advantages of efficient, hydronic heating in combination with either conventional cooling, or the heating/cooling capacities of a heat pump. Compatible with most major brands of outdoor equipment and all hydronic boilers, and water heaters. High efficiency evapo- rator coil for use with equipment up to 14 SEER.

Multiple air handlers may be connected to a single heating source for whole house heating and cooling. Each air handler includes a high efficiency cooling coil, separate hot water coil, drain pan, air filter, 120 volt variable speed blower, and multi-function microprocessor control. Optional flow control module package provides circulator pump, relay, check valve, and purge valve (ordered separately and installed outside of unit). Air handlers used with boilers normally do not require optional flow control module package. R-22 refrigerant.

Note: Use of third party (First Company) air handlers with outdoor units will not allow registration upgrades from the standard manufacturers warranty on the outdoor unit.
