Drytech designs and manufactures a range of pipeline dryers or in line dehydrator cartridges that are used for purifying and drying ECS/engine bleed air for waveguide pressurization. These inline filters can also be used in specialized compressed air or gas systems. Typical effluent dew points achieved are < -65°C DP. By selection of different types of zeolites, other contaminants can be removed as well as moisture vapor.
