Air Conditioning Central Systems Parks - Cramer Company Fitchburg, Mass. Charlotte, N. C. Atlanta, Ga. CERTIFIED CLIMATE Industrial air conditioning systems, including humidifying or dehumidifying, cooling by evaporation or refrigeration, ven tilating,Altering, air washing; with automatic control of hu midity, temperature and air change. Engineered, manufac tured, installed and serviced by Parks-Cramer. i I?;' M 2$ Air Conditioning Parks - Cramer Company Fitchburg, Mass. Charlotte, N. C. Atlanta, Ga. Industrial Humidifying and Air Conditioning Since 1904 AUTOMATIC AIRCHANGER An improved system of forced air change and distribution used with direct humidi fication. Insures fixed uniform humidity and maximum evaporative cooling. Amount of air change and operation of humidifiers controlled by humidity and temperature Psychrostat. Designed for either complete new installations or for supplementing existing direct humidify ing equipment, especially Gradumatics. Includes heating, refrigeration, filtering, where needed. GRADUMATIC HUMIDIFYING SYSTEM Vastly improved direct humidifying system for use alone, with Airchangers, or as booster for Central Station system. Air and water under pressure, water pressure always less than air. Safe. Economical. Humidifier is self-cleaning. CENTRAL STATION AIR CONDITIONING A complete system for conditioning the factory atmosphere, with positive circulation and controlled ventilation. One or more air washer units. High humidifying and evaporative cool ing capacity. Heating, filtering, and refrigerated cooling where needed. Ducts with adjustable outlets distribute conditioned air uniformly. Slight air pressure also improves uniformity. Centralized maintenance. Used with or without booster hu midification. Under gradual acting automatic control. Exclu sive multi-speed control of fan improves economy. Central Station Air Washer Units. Nozzles and Self-Cleaning Tank Screens for Central Station Air Washers. LABORATORY AIR CONDITIONING An essential of a good testing laboratory is adequate and'dependable air conditioning. Accuracy in testing is maintained only when samples and testing equipment are free from fluctu ations in both temperature and humidity. A vertical or hori zontal unit is located within or adjacent to the laboratory. Includes equipment for heating, humidifying, dehumidifying, refrigeration, circulation, and adjustable recorder-controller. Heat by steam or electricity. 1236 tit. "Cl V. H Has few component parts, easy to take apart and reassemble. Proper operation as sured without testing. No adjustment required. When humidification is needed, heads operate continuously, evaporative output being varied gradually and auto matically by Certified Climate Psychrostat to suit requirements for constant humid ity at all times. CERTIFIED CLIMATE PSYCHROSTAT For gradual control of humidity and temperature. Improved model more sensitive than ever before. Rugged and reliable. Use of the wet and dry bulb principle permits Psychrostat to perform the many and varied tasks in the field of humidity and temperature control which contribute to the success of Certi fied Climate systems. THE PETTIFOGGER (not illustrated) A compact centrifugal humidifier, with fan, for offices, storerooms, experimental rooms, hospitals, or other isolated departments. Self-contained in lacquered copper casing. Easily connected to water and electrical supplies. Automat ic control. Adjust able capacity. 1237
