Air Conditioning Atmospheric Gonditiozving Corporation Monadnock Block Chicago Main OJice 921 Lafayette Building Philadelphia Singer Building New York Territorial Offices in the Principal Cities of the United States Also Throughout Canada and London, England Humidifying, Dehumidifying, Cleansing, Cooling, Humidity Control Modern Ventilation Modern Ventilation practice demands the removal of dust and foreign matter from incoming air whether it be for in suring comfort or providing healthful con ditions for audience, student or employee and applies to efficiency and accuracy in many manufacturing processes. Of more importance, however, is the maintenance of the proper relative hu midity by the addition or removal of mois ture from the air according to season or local conditions. The design, manufacture and in some cases the installation of air conditioning apparatus in many types of buildings is our sole undertaking and during fifteen years of research and practice we have furnished hundreds of equipments with remarkable results. In Schools, Auditoriums, Theatres, Ball Rooms, Dining Rooms, Cafes, Court Rooms and all spaces where people gather in large numbers our type of equip ment has become essential. Humidifiers have been furnished for' producing and maintaining the proper relative humidity. Webster Spray Nozzle Used in All Atmospheric Installations Dehumidifiers have been installed in Industrial Plants where excessive humid ity must be removed, for drying or process work. This being accomplished either by evaporation of the spray water or the use of artesian well water. In many cases it is found necessary to resort to refrigeration and in this type of equipment we have excelled.

The removal of excessive humidity when high moisture content in the air prevents .proper drying or carrying out of certain processes. Maintaining either high or low tempera tures where local conditions or specific ma terials demand such treatment. The maintenance of uniform humidity conditions within 2 per cent of that for which control is set. The maintenance of working space at the Comfort Zone to insure efficiency of employees. 236 .

Webster Air Washers Type .A Apparatus, designed primarily for air washing in connection with ventila ting systems in public buildings, where a moderate cooling effect by evaporation is desired. Type B Apparatus, designed for air washing in public buildings and industrial plants, where the greatest possible cooling effect by evaporation is desired. Webster System of Humidity Control may be applied to the various types of Webster Air Washers, Humidifiers and Dehumidifiers. Perfect in principle and accurate in operation--the chief control ling thermostat subject to water, a me dium with four times the specific heat of air. Service Each Air Conditioning problem is a separate study and it has been found im possible to set forth in catalogue or bulletin form such information as would apply to any specific case except in a general way. We have such catalogues and bulletins as would give the prospective purchaser a general idea as to what the apparatus would consist but we find that in the end a personal interview is desirable. We gladly render service to those in terested, in the form of recommendations Atmospheric Dehumidifier, in successful operation since 1918 in large plant manufacturing food products and quotations, no charge being made ex cept for actual equipment furnished. We will not undertake a contract where we cannot accomplish just the results the buyer wishes, but where w;e do accept an undertaking we will give our best thought and skill to its complete accomplishment. 237
