Champion CRH Series High Inlet Temperature Refrigerated Air Dryer – 100 SCFM

The Champion CRHA100A1 is the flagship of the CRH Series—a high inlet temperature refrigerated compressed air dryer rated at 100 SCFM and purpose-engineered for reciprocating air compressors up to 25 horsepower. Built to accept inlet temperatures as high as 200°F (93°C) directly off a piston compressor discharge, the CRHA100A1 eliminates the need for a separate aftercooler—reducing footprint, installation time, and total installed cost while delivering reliably dry air to paint booths, sandblasting cabinets, CNC machines, and plant air mains.

Engineered for Hot, Humid Compressor Discharge

Reciprocating compressors discharge air at temperatures significantly higher than rotary screw machines—often 160°F to 200°F under load. Standard refrigerated dryers stall, freeze the evaporator, or run out of capacity when fed air this hot, forcing shops to install a pre-cooler, double up dryer capacity, or accept wet air downstream. The Champion CRH Series solves the problem with a heat exchanger and refrigerant circuit deliberately sized for hot, humid inlet conditions. The CRHA100A1 maintains a stable +50°F pressure dew point at full rated load—even when the ambient room is warm and the compressor has been running hard for hours.

R513A Refrigerant — A Lower-GWP, Future-Proof Design

The CRHA100A1 ships factory-charged with R513A, an HFO-blend refrigerant with a global warming potential roughly half that of legacy R134a. As the U.S. EPA, the AIM Act, and provincial regulators across Canada continue phasing down high-GWP refrigerants, equipment built around R513A is positioned to comply with current and upcoming F-Gas and SNAP requirements without service interruption. For facilities tracking sustainability targets, this is a meaningful environmental and procurement credit.

Technical Specifications

Ideal Applications for the CRHA100A1

The 100 SCFM rating matches steady-state demand for compressors in the 20 to 25 horsepower range—the upper end of single-phase reciprocating service and the entry point for serious production air systems. Typical homes for this dryer include high-volume auto body collision centers, multi-bay heavy truck service shops, dedicated paint shops, mid-sized manufacturing cells, CNC pump rooms, dry-air instrument loops, and small to mid-sized fabrication facilities. Pulling moisture out at this point in the system protects every tool, valve, and downstream filter in the plant.

Installation and Setup

The CRHA100A1 ships fully charged, factory-tested, and pre-wired for a standard 115V outlet. Mount the dryer downstream of your air receiver and ahead of your filtration train, allowing 12 inches of clearance above the unit for the top-mounted fan. Plumb the inlet and outlet to the 1" FNPT ports, route the drain to a sump or oil/water separator, and plug it in. Most installations are completed in under an hour.

Pair With Champion CFL Series Filters

For best dryer performance and longest service life, install a Champion CFL Grade C particulate filter immediately before the dryer to protect the heat exchanger from oil and debris, and a CFL Grade E coalescing filter immediately downstream to deliver ISO 8573-1 quality air to your point of use.

Frequently Asked Questions

Will the CRHA100A1 handle my reciprocating compressor's hot discharge?

Yes. The CRH Series is engineered for inlet temperatures up to 200°F—well above the 160–180°F typical of a hard-working reciprocating compressor. A standard refrigerated dryer would require an aftercooler ahead of it; the CRHA100A1 does not.

What dew point does this dryer achieve?

Approximately +50°F pressure dew point at full rated load. That's sufficient for general industrial applications and indoor air lines. If you need below-freezing dew points (e.g. instrument air or outdoor service), a desiccant dryer is the correct choice.

Is the CRHA100A1 large enough for a 25 HP rotary screw?

The 100 SCFM rating is matched to reciprocating compressors up to 25 HP. A 25 HP rotary screw delivers closer to 100–110 SCFM continuously and runs cooler, so the CRH Series may be undersized for a continuous-duty rotary. Contact us for sizing against your specific machine.
