SOLID STATE HIGH FREQUENCY ELECTRONIC CONTROL BOX
COOLING FAN
The most efficient ozone generator available It's the Lowther plate-type ozonator developed by Davison with Purification Sciences Inc. of Geneva, New York. Basic dielectric-coated steel electrode units are manifolded forfeed gas and 0 3 flow, and are air cooled. This plus high frequency/low voltage operation results in higher yields, easier maintenance, with less stringent feed-drying requirements. The LG-90 generator will produce 300 pounds of 2 % 0 3 per day from - 4 0 ° F dew point 0 2 . Modular units are space-efficient, too, producing approximately 8.5 pounds/day of 2 % ozone per square foot of floor OZONE CELLS space.

Improved method of concentrating 0 2 from air. Based upon Davison's extensive background in molecular sieve adsorbents, the Grace Pressure Swing Oxygen Generator is a highly versatile system capable of produc ing a wide range of oxygen concentrations (40-95%) from compressed air at room temperature. And at a low cost, thanks to im proved design. So it's adaptable to a large number of applications in water pollution control and chemical processing.
