IN PFIZER WORKROOMS A constant iow humidity is vital to operations centering around the production of penicillin, streptomycin and similar drugs. That's why Chas. Pfizer & Company, Inc. takes such care to exclude moisture from workrooms like that pictured here. Air from t h e r o o m s served b y this CHX Lectrodryer is constantly recirculated through this DRYing machine, holding it at 12% relative humidity. About 5% make-up air is added. Action of the machine is automatic, with fresh beds of Activated Alumina being brought into the air stream every few minutes, while others go out of service for reactivation. Have you a problem in DRYing? Our engineers will recommend equipment to handle the job, calling on many years of experience to advise you. Lectrodryers are DRYing air, gases and organic liquids in thousands of plants all over the world.
