Refrigerated Air Dryer

Simple, Reliable, Inexpensive, and Easy to Maintain

Dry air doesn't have to be complicated. A refrigerated dryer cools compressed air down to around 35°F, water condenses out, and you get air that's dry enough for most shop tools, air motors, and general industrial use – without spending a fortune on energy or maintenance. 

No purge air, no heater, no complex controls. Just plug it in, set it, and walk away. With a typical pressure drop of less than 0.02 MPa (3 psi) and maintenance intervals of up to 8,000 hours, it quietly protects your pipes, valves, and pneumatic components year after year. 

For SMT lines, packaging equipment, spray painting booths, and your everyday compressed air system, this is the workhorse that never complains – reliable, efficient, and ready to run 24/7.

Frequently Asked Questions

What is a nitrogen generator, and how does it work?

A nitrogen generator is a device that produces nitrogen gas (N₂) from compressed air. It uses separation methods, such as Pressure Swing Adsorption (PSA) and Membrane Technology, to remove oxygen and other gases, leaving purified nitrogen gas.

What are the advantages of having a nitrogen generator over purchasing bottled nitrogen?

Cost savings: Long-term savings are achieved by eliminating the recurring costs of purchasing bottled nitrogen.

Convenience: Continuous on-site nitrogen generation eliminates the need for deliveries and reduces the risk of running out of nitrogen.

Customization: On-demand nitrogen generation allows you to tailor the flow and purity to your needs.

What is the difference between PSA and membrane nitrogen generators?

PSA (Pressure Swing Adsorption): Uses carbon molecular sieves to separate nitrogen from other gases in compressed air under varying pressure.

Membrane Technology: This technology uses selective permeable membranes to separate nitrogen from oxygen based on the size of the molecules.
