    • High Inlet Temperature Air Dryer

    CompressorPros carries high inlet temperature air dryers built to handle compressed air that arrives warmer than standard dryers can manage, up to 180 degrees F. This category serves shops installing a dryer close to the compressor or operating in hot environments. Browse Quincy and Chicago Pneumatic refrigerated models from 25 to 125 CFM, all shipping free, direct from the manufacturer.

    What Are High Inlet Temperature Air Dryers?

    A high inlet temperature air dryer is a refrigerated dryer engineered to maintain its rated performance when the incoming air is hotter than a standard dryer is designed to accept, typically up to 180 degrees F. Compressed air leaves the pump hot, and a standard refrigerated dryer is usually rated for an inlet around 100 degrees F. When a dryer sits close to the discharge, runs in a hot room, or follows a compressor without much cooling in between, that incoming air can exceed the rating, which quietly cuts the dryer's effective capacity and lets moisture slip through. These units are built for exactly that situation, and the category spans models like the Quincy QRHT 25 through the Chicago Pneumatic CPXHT125.

    Why Inlet Temperature Matters

    A refrigerated dryer's capacity rating assumes a specific set of conditions, and inlet air temperature is one of the most important. Every degree above the rating reduces how much air the dryer can actually process to its stated dew point.

    The practical consequence is that a standard dryer rated at your CFM can still underperform if it is fed hot air. Shops discover this as moisture reaching the tools despite having a correctly sized dryer on paper. The usual culprits are a dryer mounted right at the compressor discharge, a compressor room without adequate ventilation, or a hot climate.

    A high inlet temperature dryer solves this by being rated for warmer air from the start, so it holds its dew point where a standard unit would fall short. If you cannot place your dryer well downstream of the discharge, or your installation runs hot, this is the category to match to your compressor.

    Product Series

    Quincy QRHT Series

    The Quincy QRHT line covers high inlet temperature refrigerated drying across a broad capacity spread, from 25 CFM through 125 CFM. The Quincy QRHT 50 and Quincy QRHT 75 sit in the middle of the range, matching common mid-size compressors installed in warm conditions. The Quincy QRHT 100 covers larger flow rates.

    Chicago Pneumatic CPXHT Series

    The Chicago Pneumatic CPXHT line offers the same high inlet temperature capability across a parallel capacity range. The Chicago Pneumatic CPXHT25 suits smaller shops, with the CPXHT50 and larger models scaling up to 125 CFM. Both series deliver refrigerated drying, so the choice often comes down to matching an existing compressor brand or preferred supplier.

    Schulz SMH Series

    Schuz offers high inlet temperature dryers from 30 to 100 CFM. The SMH 30 High Inlet Temperature Dryer is a very common size. Schulz produces quality air dryers at affordable prices.

    Matching Capacity to Your Compressor

    High inlet temperature dryers are still sized by CFM, and the same rules apply as with any dryer, with the inlet rating layered on top.

    • 25 to 50 CFM suits smaller shops running a single reciprocating or compact rotary screw compressor in warm conditions.
    • 75 to 100 CFM matches mid-size rotary screw units, roughly 15 to 25 HP, installed close to the discharge or in a hot room.
    • 125 CFM covers larger installations where placement or environment pushes inlet temperature above standard ratings.

    Match the dryer's rated capacity to your compressor's actual CFM output, then confirm the inlet temperature rating covers the conditions at the dryer's location.

    Key Specifications To Compare

    • Rated CFM capacity: Must meet or exceed your compressor's actual output. Undersizing lets moisture pass untreated.
    • Maximum inlet temperature rating: The defining spec here. Confirm it covers the air temperature your dryer will actually see at its installed location.
    • Pressure dew point: These are refrigerated units, delivering a dew point around 50 degrees F, suitable for general shop and tool air.
    • Voltage: Confirm the unit matches your available service before ordering.
    • Pressure drop: Every dryer costs some system pressure. Factor it into your working PSI at the tool.
    • Footprint and placement: Part of the appeal is installing near the compressor, so check dimensions for the intended spot.

    Because the whole point of this category is handling warm inlet air, verify both the CFM rating and the inlet temperature rating against your actual installation conditions.

    Frequently Asked Questions

    What is a high inlet temperature air dryer?
    It is a refrigerated air dryer built to maintain its rated dew point when incoming air is hotter than a standard dryer accepts, typically because the dryer sits near the compressor discharge or runs in a hot environment. A standard dryer in those conditions loses effective capacity and lets moisture through.

    How do I know if I need one?
    If your dryer must be installed close to the compressor, your compressor room runs hot, or you have sized a standard dryer correctly but still see moisture at the tools, a high inlet temperature unit is likely the fix. The tell is moisture getting through despite a dryer rated at your CFM.

    Do these dryers reach a lower dew point than standard ones?
    No. They are refrigerated dryers typically have a dew point around 50 degrees F dew point, but they hold that performance under hotter inlet conditions. For dew points below freezing, you would need a desiccant dryer instead.

    Can I just install my dryer farther from the compressor instead?
    Adding distance and an aftercooler or drop leg can lower inlet temperature, and sometimes that is enough. When layout, space, or climate make that impractical, a high inlet temperature dryer is the direct solution.

    What is the most common mistake when specifying a dryer near the compressor?
    Sizing by CFM alone and ignoring inlet temperature. A dryer rated at your flow rate but fed air hotter than its inlet spec will not deliver its stated dew point, which is the exact problem this category prevents.

    Does an air dryer reduce my system pressure?
    Every dryer introduces some pressure drop, which should be accounted for when calculating pressure available at the tool. Check the specification on the product page and factor it into your system design.
