Tsunami RSD-220 220 CFM Refrigerated Air Dryer – 1-1/2″ NPT, 230V

Short Product Description

The Tsunami RSD-220 Refrigerated Air Dryer provides reliable moisture removal for compressed air systems up to 220 CFM . Designed for manufacturing, CNC machining, fabrication, automotive facilities, and other industrial applications, the RSD-220 helps protect compressed air piping, pneumatic equipment, and production processes from damaging moisture.

Featuring 230V single-phase power , 1-1/2″ NPT connections , an integrated automatic condensate drain, and less than 1 PSI pressure drop, the RSD-220 delivers dependable refrigerated air treatment for larger industrial compressed air systems.

Full Product Description

The Tsunami RSD-220 Refrigerated Air Dryer is engineered to remove excess water vapor from compressed air before moisture reaches downstream piping, pneumatic equipment, machinery, and production processes.

Rated for 220 CFM , the RSD-220 cools incoming compressed air so water vapor condenses out of the airstream. The condensed moisture is then separated and automatically discharged through the dryer's integrated condensate drain system.

The Tsunami RSD Series uses an efficient heat exchanger design to pre-cool incoming compressed air while reheating the treated air before it exits the dryer. This provides effective moisture removal while maintaining a pressure drop of less than 1 PSI .

Designed for larger compressed air systems, the RSD-220 operates on 230V / 1 Phase / 60 Hz power and runs automatically once properly installed.

Frequently Asked Questions

What is the airflow rating of the Tsunami RSD-220?

The RSD-220 is rated for 220 CFM under its rated operating conditions.

What dew point does the RSD-220 provide?

The Tsunami RSD Series is designed to provide an approximate 37.4°F to 50°F refrigerated dew point , depending on operating conditions.

Does the RSD-220 include an automatic drain?

Yes. The dryer includes an integrated electronically controlled condensate drain that automatically removes collected moisture.

What electrical power does the RSD-220 require?

The RSD-220 operates on 230V, single-phase, 60 Hz power .

What size air connections does the RSD-220 use?

The RSD-220 uses 1-1/2″ NPT inlet and outlet connections .

What is the maximum pressure rating?

The RSD-220 has a maximum rated inlet pressure of 232 PSI .

What is the maximum inlet air temperature?

The maximum rated compressed air inlet temperature is 130°F .

Do I need a prefilter before the dryer?

Yes. Upstream filtration helps prevent oil and particulate contamination from accumulating inside the dryer's heat exchanger. Tsunami also requires a prefilter as part of the RSD Series warranty requirements.

How should I size the RSD-220?

Dryer sizing should account for airflow, inlet pressure, inlet air temperature, ambient temperature, and desired outlet dew point . Changes in operating conditions can increase or decrease the dryer's effective airflow capacity.
