System technology from Viessmann
Nu-Air HA Series is a hydronic air handler, which works directly with a Viessmann boiler to provide perfectly conditioned air for any home or small commercial building all year round. Heating capacity: 25 - 102 MBH, cooling capacity: 1 - 3 tons.
Ideal cooling & dehumidification
When combined with an evaporator coil and air-conditioning unit.
Flexible installation
With built-in filter rack for upflow, downflow, and horizontal installations.
Peace of mind
Integrated safety sensors provide constant monitoring of your home in case of thermostat failure.
Maximum comfort for your home
The Nu-Air HA Series uses micro-processor control technology for maximum comfort by providing warm or cool comfortable conditioned air with the quietest of operations. The integrated control logic provides efficient management of multi-stage heating and cooling systems allowing for greater energy savings, reduced utility bills and a healthier indoor environment.
During the heating cycle, the high efficiency ECM fan motor provides a gradual flow of warm comfortable air without the noise and on/off operations of typical set speed PSC blowers.* This gradual increase of fan speed prevents the circulation of cool air and also allows your ductwork to warm up reducing duct expansion noises.
Optimum efficiency
Unlike standard forced air furnaces, the Nu-Air HA Series is capable of covering a wider range of heating output. This allows the unit to precisely match the heating load of even the most energy efficient homes. With this wide range of outputs, there are fewer on/off cycles, reducing wear and tear on the unit, increasing longevity and optimizing fuel efficiency.
