A BWC-750 Lectrodryer dries all compressed air delivered to the various chemical, metallurgical and liquefaction research jobs at the Air Reduction Research Laboratories, Murray Hill, New Jersey.
Clean, DRY air is part of their formula at (KRCO) # # • Air that's clean and D R Y to a measured degree, won't upset the delicate c o m p o u a d i n g of chemicals and gases. In fact, clean D R Y air is an ingredient which many times e o a b l e s an experiment to succeed. Air R e d u c t i o n R e s e a r c h L a b o r a t o r i e s obtain a constant supply of clean air at a preset l o w relative humidity by the c o m b i n e d use of a Lectrodryer* and Lectrofilter* installed at their air compressors. Perbaps you can benefit by a similar installation. Lectrodryers can D R Y air and gases in volume to dewpoints b e l o w — 1 0 0 ° F . . . . can

These constant conditions are obtained continuously, automatically and economically. If your research, production processes or manufacturing space require l o w relative humidity, learn m o r e about types of Lectrodryers available.
