Tsunami RSD-175 175 CFM Refrigerated Air Dryer – 1-1/2″ NPT, 115V

Short Product Description

The Tsunami RSD-175 Refrigerated Air Dryer provides reliable moisture removal for compressed air systems up to 175 CFM . Designed for manufacturing, CNC machining, fabrication, automotive facilities, woodworking, and other industrial applications, the RSD-175 helps protect compressed air piping, pneumatic equipment, and production processes from damaging moisture.

Featuring 115V single-phase power , 1-1/2″ NPT connections , an integrated automatic condensate drain, and less than 1 PSI pressure drop, the RSD-175 delivers dependable refrigerated air treatment for larger shop and industrial compressed air systems.

Full Product Description

The Tsunami RSD-175 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 175 CFM , the RSD-175 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 air-to-air heat exchanger to pre-cool incoming compressed air while reheating the treated air before it exits the dryer. This process provides effective moisture removal while maintaining a pressure drop of less than 1 PSI .

The RSD-175 operates on 115V / 1 Phase / 60 Hz power and is designed for automatic everyday operation once properly installed.

Technical Specifications

Why Choose the Tsunami RSD-175?

The RSD-175 provides 175 CFM of refrigerated drying capacity while still operating on 115V single-phase power. Its larger 1-1/2″ air connections help accommodate higher system airflow, while the 232 PSI maximum pressure rating provides flexibility for a wide variety of compressed air applications.

For facilities operating larger rotary screw compressors or multiple pneumatic processes, the RSD-175 provides an effective way to reduce moisture before compressed air reaches valuable downstream equipment.

Warranty

Tsunami RSD Series refrigerated dryers are covered for 18 months from the factory shipment date or 12 months from installation/start-up, whichever occurs first , subject to Tsunami's warranty requirements.

A properly sized prefilter and non-corrosive upstream piping are required for warranty coverage.

Frequently Asked Questions

What is the airflow rating of the Tsunami RSD-175?

The RSD-175 is rated for 175 CFM under its rated operating conditions.

What dew point does the RSD-175 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-175 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-175 require?

The RSD-175 operates on 115V, single-phase, 60 Hz power .

What size air connections does the RSD-175 use?

The RSD-175 uses 1-1/2″ NPT inlet and outlet connections .

What is the maximum pressure rating?

The RSD-175 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 solid particles and oily residue 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-175?

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.
