AIR WASHER CERTIFIED CLIMATE A complete system for conditioning the factory atmosphere, with positive air circulation and controlled ventilation. One or more air washer units. High humidifying and evaporative cooling capacity. Heating, filtering and refrigerated cooling where needed. Ducts with adjustable outlets distribute condi tioned air uniformly. Slight air pressure also improves uni formity. Centralized maintenance. Used with or without booster humidification. Under gradual acting automatic con trol. Multi-speed control of fan improves economy. Central Station Air Washer Units. Nozzles and Self-Cleaning 'Tank Screens for Centra! Station Air Washers. AUTOMATIC AIRCHANGER Improved system of forced air change and distribution used with direct humidification. Insures fixed uniform humidity and and maximum evaporative cooling. Amount of air change, operation of humidifiers under gradual automatic control. For complete new installations or for supplementing existing direct humidifying equipment. Includes heating, refrigeration, filter ing, where needed. With or without ducts. DIRECT HUMIDIFICATION Atomizer humidifier for all uses. Evaporative capacities up to 16 pounds of water per hour. Turbomatic--gravity type, onana-off, fixed output, several sizes. GraduVac--full range modulating control, applicable to any gravity type atomizer system. Gradumatic--water under pressure, full range modu lation. All types--self-cleaning, used alone or with Airehangers or as boosters for air washer systems. LABORATORY AIR CONDITIONING An essential of good testing is adequate and dependable air conditioning. Accuracy in testing is maintained only when samples and room atmosphere are free from fluctuations in both temperature and humidity. A vertical or horizontal unit is located within or adjacent to the laboratory. Includes equip ment for beating, humidifying, dehumidifying, refrigeration circulation, filtering. Adjustable recorder-controller Heat by steam or electricity. CERTIFIED CLIMATE REGULATION Air-conditioning (CH-type) LEdPODRYERS arc used for automatic lowering of relative humidities in many types of industrial applications INDEPENDENTLY CONTROLLED DEHUMIDIFICATIQJ TOR INDUSTRIAL APPLICATIONS AND AIR CONDITIONING Air-conditioning (CH-type) Lectrodryers provide an efficient, economical means of dehumidification in industrial areas in winch the material in process or in storage requires a relatively dry atmosphere. Lectro dryers are used for this purpose in pharmaceutical houses, food processing plants, metal storage areas, and many types of packaging plants. The uninterrupted production, higher quality and safer storage made pos sible by the introduction of dry air in such applications often save the user many times the cost of the Lectrodryer. In addition, operating costs are negligible. The dehumidification process is continuous and com pletely automatic. It is completely independent of any air-conditioning apparatus that might serve the same general area. If cooling is desired along with dehumidifi cation--either for comfort air conditioning or in con junction with an industrial application--an after-cooler is mounted directly on the Lectrodryer. Wide Range of Sizes and Capacities Relative humidities of 35 percent or lower are obtained with standard CH-type Lectrodryers. Capacities range from 350 cfm to as high as 15,000 cfm. Moisture is re moved from the air by means of a solid adsorbent-- activated alumina--with automatic reactivation being ^ accomplished by gas, steam or electricity. Lectrodryers require almost no maintenance. The only moving parts are the motor and blowers, and the valve drive mechanism. Units are shipped completely as sembled, ready for easy installation. All are manu factured to rigid standards that have made Lectro dryer one of the world's foremost manufacturers of adsorbent dryers. Write for full details.
