Problem:
Imagine producing dry high-pressure air (1000–6000 psig compressor discharge pressure) without the expense of complex equipment and maintenance issues associated with the constant cycling valves and desiccant replacement. (back to top)
Solution:
CACTUS® High-Pressure Air Dryers make air drying for high-pressure applications simple. They have no moving parts and can be installed and operated at up to 1200 psig between stages of a high-pressure compressor or as a freestanding unit after the compressor. The only maintenance is regular replacement of the filter elements upstream of the membrane. Save money on the regular replacement of valves and desiccant with the CACTUS High-Pressure Air Dryer.

Benefits:
-
Simple to operate. They contain no moving parts.
-
Smaller than desiccant dryers of comparable capacity.
-
Lower life-cycle cost than desiccant dryers.
-
Used by the US Navy to replace all desiccant dryers on aircraft carriers. (back to top)

Performance:
Three models, HD-4020, 4030, and 4050, are offered to accommodate various feed pressures and air flow rates (see chart below). The dehydrators are designed to operate with feed pressures from 400 to 1200 psig and feed flow rates from 20 to 170 SCFM at inlet temperatures of 65–135°F to produce dew points of –70°F (atmospheric) or lower. The purge loss is less than 10% of the rated flow. The dehydrators, with stainless steel shells, are 6" in diameter and vary in length from 42 to 53 inches.
