Water Source Heat Pump Now with Energy Recovery

Aylmer, Ontario - 14 October 2008

The Senior Series represents a rather new addition to a line of customizable air handling units specifically designed for school classroom ventilation and heating and cooling needs. In particular, the Senior Series offers a water source heat pump design compatible with either water-loop (traditional boiler/cooling tower application) or geothermal applications. Now, the Senior Series is also offered with an energy recovery option.

Energy recovery takes place through the addition of an dessicant wheel. The wheel is constructed of a lightweight polymer and coated with a permanently bonded gel desiccant. A stainless steel frame provides rigid support. The wheel is AHRI certified.

When the wheel is integrated into the Senior Series air handler, its true power is realized. The Senior Series offer an impressive list of classroom advantages. Available in 2.5 to 7-ton capacities with standard scroll compressors. Supply air velocities range from 1000 to 2000 CFM.

With the energy recovery option, 70-80% effectiveness is realized, resulting in up to 30,000 BTU/hour of recovered energy. An economizer damper, with full bypass of the recovery wheel is standard with the energy recovery option. The wheel is available with one or two relief fans providing from 450 to 800 CFM.

Maintenance was a primary consideration in the design of the Senior Series. Filters are easily accessible. The recovery wheel is washable with detergent or an alkaline coil cleaner and water. For major repairs, the entire wheel matrix is easily removable.
