To select the Niagara Coolers with capacity to maintain a given room temperature, take from factor table the factor at desired room temperature and refrigerant temperature. Then divide the required B.T.U. absorption by this factor which will give a required rating. The corresponding rating may be selected from the basic rating table. 564 Niagara Blower Company Air Conditioning NIAGARA FAN HEATERS For the heating and ventilating of large areas, industrial plants storage buildings, etc. Especially recommended for packing plants, dye houses and wherever ventilation is required Niagara Fan Heaters put the heat immediately where needed in the working zone, give quicker heating up to working temperatures, prevent cold floors, cold corners.
