Modine Mfg. Co.: DX and Heat Pump SystemThe Airedale ClassMate® single packaged vertical DX and heat pump system has been redesigned. It offers efficiency, noise reduction, and a smaller footprint, providing great flexibility for school installations, said the company. The system is offered in four capacities, from 24-60 MBtuh in two cabinet sizes. Inside the new unit is the CF® microchannel evaporator coil. The smaller coil, combined with a reduced refrigerant charge and airside pressure drop, allows extra space to be opened up for multiple supplemental heat exchangers such as a hot gas reheat coil, hot-water coil, or electric heat elements. According to the manufacturer, the result is a more compact model that does not require a plenum for additional heat and reduced installation time. Features include modulating, electronically commutated fan motors; availability of combination energy recovery and economizer modules, permitting either heat recovery for outside air or fully modulating 100 percent economizer; front access to all components; use of R-410A refrigerant; and modulating economizer damper for 100 percent free-cooling and fresh-air requirements. Optional features include factory-supplied BACnet- or LonWorks-compatible controls, hot-water heating coil and valve/piping packages for hydronic heating options with top or bottom connections, and demand control ventilation.
