Compact, reliable, without electricity needed
The High Pressure Dryers are designed to be used in critical applications where clean-dry-air is essential for continuous operations.
The High Pressure Dryers are encased in a 316L stainless steel shell with 1-inch JIC flare fittings to connect into your system. The High Pressure Dryers are routinely used between stages of multi-stage compressors to remove moisture before the final compression step. They are capable of handling very high pressures up to 1200 psi (82 Barg) to address some of the most demanding air supply requirements.
The high pressure membrane dryers are manufactured with durability and performance in mind. They use no electricity, making them ideal for use in remote applications, compressor stations, or shipboard installations. Built from high-performance stainless steel, The high-pressure dryers withstand the most grueling environments.
The principle is simple, but very effective. As air at high-pressure flows along the outside of the membrane fibers, water is removed by selective permeation. Dry air exits at the opposite end. For optimum performance, a user-adjustable portion of the dried air is injected as a purge stream.
