The DHP Series of blower purge desiccant air dryers ensures that your dry air requirements are met. The DHP can provide you with ISO 8573.1 Class 2 dewpoints. Couple your DHP dryer with the appropriate FIL filtration to achieve up to ISO 8573.1 Class 1 for solids and oils.
Gardner Denver DHP externally heated series is designed for applications that were previously forced to accept a -40° F pressure dew point when simple protection against seasonal freezing is the issue. The standard design delivers ISO 8573.1 dew points between Class and Class 3 automatically. Class 2 (-40°) dew points protect against freezing during low ambient conditions and class 3 (-4° F) dew points keep your air system bone dry during the heat of summer. Applications that require class 2 (-40°) dew points year round simply need to select controller A or B.
