SPX Deltech Desiccant Dryers


WM Series Heatless Dryers

5 - 25 scfm



Minimum purge air usage saves the heat of adsorption, maximizing the moisture holding capacity of the purge air which minimizes the amount required. Standard 10 minute cycle gives increased desiccant life over units operating on shorter cycles. WM Series dryers allow the off-stream tower to fully repressurize before going on-stream preventing bed movement and loss of pressure downstream.

ZP Series Blower Purge Dryers

500 - 4300 scfm



ZP Series dryers improve air system efficiency by the use of a dedicated axial blower, instead of a percentage of dehydrated purge air, to regenerate the off-line desiccant tower. ISO 8573.1 Class 2 (-40°F/-40°C) dew point performance is guaranteed. HBP Series compressed air dryers will produce the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig.

HOC Series Heat of Compression Dryers

3750 - 10000 scfm



The Deltech HOC Series provides a cost effective solution to remove moisture from compressed air. The sustainable energy saving design reduces operating costs and delivers instrument quality air. Thermal energy generated during the air compression process is effectively utilized to regenerate the off-line desiccant bed. Ideally suited for oil-free air compressors, HOC series dryers turn “waste heat” into energy savings.

RP Series Externally Heated Dryers

250 - 3200 scfm



Deltech RP Series dryers will produce the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig. 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 2and Class 3 automatically. Class 2 (–40°F) 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°F) dew points year round simply need to select the Free-Air (FA) Supercharger option package.
