FS-Curtis RNB600 Non-Cycling Refrigerated Dryer 600 SCFM #FRNB00600-4XA5XX

FS-Curtis RNB600 — 600 SCFM Refrigerated Air Dryer

When a large rotary screw compressor outpaces its dryer, the symptom isn't a dramatic failure — it's a slow creep of wet air complaints, corrosion in the lines, and a maintenance team that can't figure out why moisture keeps showing up downstream. The RNB600 exists to remove that bottleneck at genuinely high continuous throughput, matched to the compressor instead of choking behind it.

That's what the FS-Curtis RNB600 solves — a 600 SCFM non-cycling refrigerated dryer, engineered to run reliably through a full shift without needing anyone to check on it. It's also available with a factory-matched Filter Package (prefilter CF7-44-20-DG + afterfilter CF5-44-20-DG) as an add-on option, which folds the particulate and coalescing filtration into the same purchase, sized correctly the first time.

Who the RNB600 Is Built For

• ✅ An industrial facility or large commercial shop running a high-output rotary screw compressor that needs matched, continuous-duty drying capacity
• ✅ An operation with a centralized compressed air system feeding multiple work areas, production lines, or bays from one header
• ✅ A facility that needs dependable, round-the-clock dew point control at high SCFM without the pressure drop that undersized filtration or dryers introduce
• ✅ A plant manager replacing an aging industrial dryer who needs the new unit to match or exceed the old one's throughput without a costly re-pipe of existing 2-inch/3-inch/4-inch flanged connections
• ✅ An operation where compressed air system downtime for dryer service is expensive, making reliability and manufacturer-backed 2-year coverage a real purchasing factor, not an afterthought

What the RNB600 Is NOT Built For

• ❌ Small or mid-size shops — this tier is sized for industrial-volume air systems and is oversized, and overpriced, for a single-bay or light commercial operation
• ❌ Facilities without existing 3-phase power infrastructure or the floor space and flanged/NPT piping this unit's footprint and connections require

What Makes the RNB600 Different

Heat Exchanger

The RNB600 uses a stainless steel brazed plate heat exchanger, engineered for reliable, consistent dew point control at 600 SCFM without fouling or excess pressure drop.

Condensate Drain

Timed electric drain removes collected moisture automatically — it's set-and-forget — the timer opens and closes the drain automatically, shift after shift.

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 (CF7-44-20-DG) and afterfilter (CF5-44-20-DG), sized to this dryer's flow rate and ready to plumb — one less step for your install crew.
