Produce 100% Efficient Air Systems

Compressed air users rely on Deltech to provide compressed air treatment solutions for applications around the world. 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.

Reduce Energy Consumption

As the air compressor is the most costly system component to purchase and it uses more electrical energy than the rest of the system combined, it is wise to ensure that the smallest air compressor is installed. ZP series dryers are 100% efficient at delivering full supply side compressor capacity.  Therefore, users benefit from the ability to purchase a less expensive air compressor and, a 20% reduction in compressor operating costs.

Filtered compressed air enters on-line desiccant-filled, drying Tower 1 through valve (A). Up-flow drying enables the desiccant to strip moisture from the airstream.  Clean, dry compressed air exits through (E) to feed the air system. Tower 2 (shown in regeneration mode) valve (B) closed, depressurizes to atmosphere through muffler (C). Valves (D&F) open and the heater turns on. 

The high-efficiency blower draws ambient air and feed it through the heater.  The ambient stream passes through valve (F) and flows downward through the moist desiccant in Tower 2, collecting water vapor before exiting valve (D).  Once the desiccant is fully desorbed, the heater turns off.  Valves (F&D) close and Tower 2 is repressurized. 

At a fixed time interval, valve(B) will open and Tower 2 will be placed on-line to dry the air stream and valve (A) will close.  Operations switch and Tower 1 will be regenerated.
