This machine protects equipment in storage by maintaining a relative humidity of S5 per cent or lower. Small automatic air conditioning type LEC* TRODRYER used for providing lowered rel ative humidities. FOR INDEPENDENT CONTROL OF DEHUMIDIFICATION IN COM FORT AND INDUSTRIAL AIR CONDITIONING The results of years o." experience in the independent control of industrial de humidification are now available for com fort air conditioning in the form of system, only the air needed for the sensi ble heat load is cooled and no reheat is required. Machines are available for steam, gas sturdy, dependable, thoroughly tested or electric operation, whichever the pur machines for controlled adsorption de chaser specifies. Standard machines are humidification. available in several sizes ranging from 350 cfm upward. 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 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. eration or water cooling. With this type Write for full details. 1113
