Description
Chicago Pneumatic CPXHT50 (H2) 50 SCFM High-Temperature Refrigerated Air Dryer, 1" NPT, 115V/1Ph - PN 4102003869
High-Temperature Moisture Removal for 10 to 15 HP Reciprocating Air Compressors
The Chicago Pneumatic CPXHT50 High-Temperature Refrigerated Air Dryer, part number 4102003869, is engineered to remove moisture from compressed-air systems operating with elevated inlet-air temperatures.
Rated for 50 SCFM at 100 PSIG, the CPXHT50 can accept compressed-air inlet temperatures up to 180°F. This high-temperature capability makes it an excellent match for many 10 to 15 HP reciprocating air compressors, including systems that do not have a separate air-cooled aftercooler.
The CPXHT50 combines a refrigerated air dryer, moisture separator, and electronic condensate drain in one compact package. As hot compressed air passes through the dryer, it is cooled so water vapor condenses into liquid. The integrated separator removes the condensate from the airflow, while the electronic drain automatically discharges the collected moisture.
With a pressure dew point of approximately 50°F ± 2°F, the CPXHT50 helps reduce water accumulation inside compressed-air piping and protects pneumatic tools, cylinders, valves, production equipment, and finished products from moisture-related problems.
The dryer operates on standard 115-volt single-phase power and uses 1-inch NPT inlet and outlet connections, simplifying installation in automotive shops, fabrication facilities, maintenance departments, woodworking operations, and other commercial or light-industrial applications.

Recommended Applications
The Chicago Pneumatic CPXHT50 is well suited for:
- Automotive repair shops
- Collision repair and body shops
- Tire-service facilities
- Fleet-maintenance departments
- Metal fabrication shops
- Woodworking and cabinet shops
- Maintenance departments
- Light manufacturing
- Paint and finishing operations
- Pneumatic assembly equipment

The dryer should be sized according to the compressor’s actual airflow, operating pressure, inlet-air temperature, and maximum ambient temperature.
Why Choose a High-Temperature Refrigerated Air Dryer?
Compressed air leaving a reciprocating compressor can be extremely hot. A standard refrigerated air dryer may not be designed to accept this elevated temperature without a separate aftercooler.
The CPXHT50 is designed to accept inlet-air temperatures up to 180°F, allowing it to handle hot discharge air from many reciprocating compressors.
Potential advantages include:
- May eliminate the need for a separate aftercooler
- Reduces installation complexity
- Saves floor space
- Reduces external piping requirements
- Automatically removes condensed moisture
- Helps protect downstream equipment
- Reduces water accumulation in air lines
- Reduces manual air-line purging
- Supports more consistent compressed-air quality
- Helps reduce moisture-related maintenance and downtime
Benefits of Dry Compressed Air
Atmospheric air naturally contains water vapor. When air is compressed, that moisture becomes concentrated. As the compressed air cools inside the receiver tank and distribution piping, the water vapor can condense into liquid.
Excessive moisture can contribute to:
- Internal piping corrosion
- Damaged pneumatic tools
- Sticking air cylinders
- Rust inside air receivers and piping
- Contaminated paint finishes
- Fisheye paint defects
- Damaged regulators and valves
- Increased equipment maintenance
- Reduced production quality
- Frozen outdoor air lines
- Unplanned downtime
The CPXHT50 cools the compressed air, separates condensed moisture, and automatically discharges the collected water.
Air Treatment Recommendations
A refrigerated air dryer primarily removes water vapor and condensed moisture. Some applications may require additional air treatment for particulate contamination, fine oil aerosols, odors, or other contaminants.
Depending on the application, the compressed-air system may also require:
- Automatic receiver-tank drain
- General-purpose particulate filter
- High-efficiency coalescing filter
- Activated-carbon filter
- Pressure regulator
- Oil-water separator
- Point-of-use air treatment
Paint spraying, instrumentation, and sensitive production applications may require additional treatment beyond a refrigerated air dryer.
Installation Considerations
The CPXHT50 should be installed indoors in a clean, well-ventilated location with adequate room for inspection and maintenance.
Before installation:
- Confirm that system airflow does not exceed the dryer’s 50 SCFM rated capacity.
- Verify that the dryer is suitable for the compressor’s actual inlet-air temperature.
- Confirm that operating pressure does not exceed 232 PSIG.
- Confirm that ambient temperature remains between 41°F and 113°F.
- Provide a 115V single-phase, 60 Hz electrical supply.
- Verify that the electrical circuit meets the dryer’s nameplate requirements.
- Use properly sized 1-inch compressed-air piping.
- Confirm the correct compressed-air flow direction.
- Keep the condenser and ventilation openings clear.
- Prevent heated exhaust air from recirculating into the dryer.
- Route the electronic drain discharge to an approved condensate collection or treatment system.
- Provide isolation valves to simplify future maintenance.
- Avoid unnecessary piping restrictions at the inlet and outlet.
- Support external piping so its weight is not carried by the dryer connections.
- Maintain the manufacturer’s recommended service clearances.
- Check the compressed-air system for leaks after installation.
Installation should be completed according to the supplied operating instructions and all applicable electrical, plumbing, and safety codes.
Routine Maintenance
Routine inspection helps maintain moisture removal, cooling performance, and dependable dryer operation.
Typical maintenance includes:
- Verify that the electronic condensate drain is operating.
- Inspect the drain discharge line for restrictions.
- Keep the condenser and ventilation openings clean.
- Remove accumulated dust and debris from cooling surfaces.
- Check the dryer for unusual noise or vibration.
- Inspect compressed-air fittings for leaks.
- Verify that inlet-air temperature remains within the rated limit.
- Confirm that ambient temperature remains within the allowable range.
- Inspect electrical wiring and connections.
- Check for excessive pressure drop through the dryer.
- Follow the maintenance instructions supplied with the unit.
Maintenance frequency can vary based on operating hours, dust levels, ambient temperature, humidity, and compressor operating conditions.
Basic Troubleshooting
Water Is Present Downstream
Check the electronic drain, drain discharge line, inlet-air temperature, airflow demand, ambient temperature, operating pressure, and dryer ventilation.
The dryer may be undersized if actual operating conditions exceed its rated capacity.
Electronic Drain Does Not Discharge
Check the drain’s electrical connection, timer operation, isolation valve, discharge tubing, and condensate outlet for blockages.
Dryer Does Not Start
Check the electrical outlet, circuit protection, power connection, dryer switch, and incoming voltage.
Dryer Runs but Does Not Remove Moisture
Verify that the refrigeration system is operating, the condenser is clean, the condensate drain is functioning, and inlet conditions remain within the dryer’s rated limits.
Excessive Pressure Drop
Inspect the compressed-air piping, valves, fittings, heat exchanger, and downstream air-treatment components for restrictions.
Dryer Shuts Down or Runs Hot
Check the ambient temperature, ventilation clearance, condenser cleanliness, and whether heated exhaust air is recirculating into the dryer.
Excessive Condensate in the Air System
Confirm that the air receiver is draining properly and that the dryer is installed and sized correctly for the compressor’s airflow and discharge temperature.
Refrigeration-system repairs, electrical repairs, internal pressure-system repairs, and major service should be completed by qualified personnel.
