FS-Curtis RNB150 Non-Cycling Refrigerated Dryer 150 SCFM #FRNBX00150-1XA5XX

FS-Curtis RNB150 — 150 SCFM Refrigerated Air Dryer

A shop that needs real 150 SCFM capacity but doesn't have 3-phase power run to the compressor room yet can still get there — the RNB150 is the largest RNB model still built for standard 115V single-phase service.

That's what the FS-Curtis RNB150 solves — a 150 SCFM non-cycling refrigerated dryer, a solid, no-surprises way to keep moisture out of the system without paying for capability this application doesn't need. It's also available with a factory-matched Filter Package (prefilter CF7-28-8-DGL + afterfilter CF5-28-8-DGL) as an add-on option, which means your install crew connects one pre-matched assembly instead of sourcing, sizing, and piping filters separately.

Who the RNB150 Is Built For

• ✅ A multi-bay shop running a mid-size rotary screw compressor (typically 15-30 HP) where several techs pull air from the same line throughout the day
• ✅ A shop that already has 3-phase power in place and wants a dryer sized to actually match the compressor's real output, instead of undersizing and choking the system
• ✅ An operation that needs consistent dew point control across a full 8-10 hour shift, not just intermittent weekend-warrior use
• ✅ A shop that's grown out of a smaller single-phase dryer and is tired of it cycling or falling behind once two or three bays are running air tools simultaneously
• ✅ A facility running sensitive downstream equipment — spray booths, sandblast cabinets, precision pneumatic tools — where wet air causes real, expensive problems

What the RNB150 Is NOT Built For

• ❌ Small single-bay shops with light, intermittent air demand — a smaller RNB model in the 115V tier saves real upfront cost
• ❌ Very high-volume industrial operations that exceed this unit's rated SCFM — check the 200+ SCFM models instead so the dryer isn't the bottleneck

What Makes the RNB150 Different

Heat Exchanger

The RNB150 uses a stainless steel brazed plate heat exchanger, engineered for reliable, consistent dew point control at 150 SCFM without fouling or excess pressure drop.

Condensate Drain

Timed electric drain removes collected moisture automatically — there's no manual valve to open — the unit clears condensate on its own timed interval.

Refrigerant & Air Quality

Uses R513A refrigerant, a low global-warming-potential option, and delivers ISO 8573-1:2010 Class 4–5 pressure dew point — dry, reliable air for general shop and industrial use.

Optional Filter Package

Choose the “Includes Filter Package” option to add a factory-matched prefilter (CF7-28-8-DGL) and afterfilter (CF5-28-8-DGL), sized to this dryer's flow rate and ready to plumb — one less step for your install crew.
