Nordair Niche gas fired air heaters incorporate a high efficiency gas fired heating coil with a lower thermal efficiency of 91%. The gas fired heating coils have a variety of advantages compared to traditional heat exchangers and enable the heat exchanger section to be closely matched with the filter sizes etc to reduce the airflow resistance and lower the specific fan power required. The heating coils also provide an excellent turn down ratio for close temperature control.
