Air Conditioning onu s^ms Pittsburgh Lectrodryer Corporation Foot of 32nd Street Pittsburgh, Pa. FOR INDEPENDENT CONTROL OF DEHUMIDIFICATION IN COM FORT AND INDUSTRIAL AIR CONDITIONING The results of years of experience in the independent control of industrial de humidification are now available for com fort air conditioning in the form of sturdy, dependable, thoroughly tested machines for controlled adsorption de humidification. LECTRODRYER equipment using Ac tivated Alumina, a solid adsorbent, is widely used in maintaining lower than normal relative humidities in the chem ical, pharmaceutical and other indus tries. In comfort air conditioning these ma chines handle the latent heat load with only the sensible heat load left for refrig eration or water cooling. With this type system, only the air needed for the sensi ble heat load is cooled and no reheat is required. Machines are available for steam, gas or electric operation, whichever the pur chaser specifies. Standard machines are -available in several sizes ranging from 350 cfm upward. t LECTRODRYERS are shipped com plete as self-contained automatic units in that they require no regular manual attention except for starting. They are built for continuous operation with reac tivation being carried on simultaneously with the drying operation. Write for full details.
