Champion XCHP Series Heated Purge Desiccant Air Dryer – External Heater Regeneration (150–1200 SCFM)

The Champion XCHP Series is an X-Series twin-tower heated purge regenerative desiccant air dryer offered in ten capacities from 150 to 1200 SCFM, delivering a -40°F (-40°C) pressure dew point at a maximum working pressure of 150 psig. An external heater conditions the regeneration air, so the XCHP restores its offline desiccant bed on a fraction of the compressed air a heatless dryer throws away. On a plant running two or three shifts, that reclaimed purge air is compressor horsepower you already paid to produce.

Every XCHP ships as a complete filtered package with a coalescing prefilter and a particulate afterfilter already mounted and piped, NEMA 4 electrical enclosures, and a 460/3/60 power connection, so the dryer arrives ready to tie into the header without a separate filtration order.

Heatless or Heated Purge: Where the XCHP Pays

Every regenerative desiccant dryer has to get the water back out of the offline tower. A heatless dryer does it with pressure alone, expanding a slice of its own dried outlet air to atmosphere and sweeping it back through the bed. It is simple and dependable, and it is also why a heatless dryer consumes a meaningful percentage of its rated flow around the clock.

The XCHP puts an external electric heater in that regeneration path. Hot purge air strips moisture out of the desiccant far more aggressively than ambient-temperature purge air, so the dryer needs much less of it to accomplish the same regeneration. You trade a modest electrical load for compressed air you stop venting, and at 150 SCFM and up that trade usually runs strongly in your favor.

If the heater ever faults, the controller drops the dryer into heatless backup mode and keeps making -40°F air on pressure swing alone. You do not lose air quality waiting on a service call.

Purge consumption varies by model, operating pressure and cycle, and Champion publishes it per configuration rather than as a single headline number. Send us your flow, pressure and run hours and we will put the XCHP, a heatless dryer and a blower purge dryer side by side on real numbers before you commit.

What Sets the XCHP Apart

• External heater regeneration: cuts the compressed air diverted to purge compared with a heatless design of the same capacity.
• Heatless backup mode: a heater fault does not take your dew point with it.
• Low-profile construction with operator-level valve access: the valves a technician actually services are at working height, not buried overhead or between the towers.
• Non-lubricated ball and butterfly switching valves: stainless steel internals and PTFE seats, with no lubrication to maintain and nothing to migrate downstream.
• Digital multi-function controller: backlit LCD readable in any light, continuous monitoring, stored failure codes, and Modbus communication for plant integration.
• NEMA 4 electrical enclosures standard: rated for indoor or outdoor installation with no enclosure upgrade.
• Prefilter and afterfilter mounted: the desiccant is protected from oil carryover and the downstream air from desiccant fines, out of the crate.
• Large sound-attenuating purge mufflers with integral relief valves: the towers vent without making the mechanical room unbearable.
• Removable stainless steel desiccant screens: pull them, clean them, put them back, instead of replacing them.
• Tower pressure gauges: confirm the dryer is cycling correctly from across the room.

Choosing Your Configuration

Configuration	What You Get	Best For
Standard -40°F	Fixed-cycle heated purge regeneration with the standard digital controller, NEMA 4 enclosures, and the mounted prefilter and afterfilter package. The dryer runs its regeneration cycle on a set schedule whether or not it is fully loaded.	Plants that run at or near steady compressed-air demand through the shift, where the dryer is loaded most of the hours it is powered.
Energy Management System -40°F	Everything in the standard unit plus dew point demand control with a digital display. The controller measures actual moisture loading and extends the drying cycle when the plant is light, so purge and heater energy track real demand instead of the clock.	Any plant with variable demand, multiple shifts or seasonal swing. The EMS premium is the single highest-leverage option on this dryer and typically pays back in energy alone.
3-Valve Bypass (with either control package)	A factory-piped bypass around the dryer and its filters, so the unit can be isolated, serviced or rebuilt without shutting the plant air header down.	Any system that cannot take a planned outage. Specify the bypass at time of order; retrofitting one in the field costs far more than the factory option.

Ideal Applications

Specify a heated purge desiccant dryer where you need a true -40°F dew point at a flow large enough that heatless purge air becomes an expensive habit: plant air headers at 150 SCFM and above, compressed air piping that runs outdoors or through unheated space and would otherwise freeze, spray finishing and powder coating lines, pneumatic instrumentation and control air, laser cutting assist gas, blow molding, pharmaceutical and food packaging, textile manufacturing, electronics assembly, and any breathing-air or critical process loop written to an ISO 8573-1 class. The XCHP is also the usual upgrade path for a plant that outgrew a heatless dryer and is now watching its purge air eat a compressor.

Factory Options

Beyond the control and bypass packages priced in the dropdowns above, the XCHP Series supports several factory-configured options quoted at time of order:

• -100°F (-73°C) Dew Point: for ISO 8573-1 humidity Class 1 applications. Low dew point operation affects rated capacity, so let us confirm sizing with the factory rather than sizing off the model number.
• Indoor Tower Insulation: reduces heat loss from the regenerating tower and improves regeneration efficiency indoors.
• High Humidity Alarm: alarms when outlet moisture rises above setpoint.
• High Outlet Temperature Alarm: alarms on elevated outlet temperature during or after regeneration.
• 575V Power and CRN Registration: Canadian Registration Number and 575V configurations are consult-factory for part number, price and lead time.

Send us your model and the options you need and we will quote the configured part number and current lead time.

Mounted Filtration and Replacement Elements

Every XCHP arrives with its prefilter and afterfilter installed. Change the elements annually, keep the drains working, and the desiccant bed will do its job for years. Element part numbers by dryer model:

Sizing, Installation and Electrical

Size the dryer to the actual SCFM passing through it at your operating pressure, not to compressor nameplate horsepower, and size for the hottest, wettest day your compressor room sees rather than the average one. Install a properly sized wet receiver tank ahead of the dryer with a working drain, keep inlet air temperature within specification, and leave service access on all sides for tower recharge and valve work.

Electrically, the XCHP is a 460/3/60 machine with NEMA 4 enclosures. Heater and full-load electrical data vary by capacity and configuration, so we confirm the exact figures with the factory for your submittal before the order ships rather than having an electrician guess at the feeder. Our engineers will review your layout and your one-line at no charge.

Desiccant Life and Service

Activated alumina in a properly filtered dryer typically gives several years of service before the bed needs recharging. The fastest way to destroy a desiccant bed is oil carryover from an upstream compressor, which is exactly why the XCHP ships with a coalescing prefilter as standard equipment. Change the elements on schedule, keep the drain working, verify the tower changeover is completing, and the bed will last. Champion supports the XCHP with replacement elements, valve seal and actuator kits, mufflers and bulk activated alumina charges; we stock and quote all of it.

Frequently Asked Questions

What dew point does the XCHP deliver?

-40°F (-40°C) pressure dew point as standard, which corresponds to ISO 8573-1 humidity Class 2. A -100°F (-73°C) Class 1 configuration is available as a factory option and is quoted on request.

Heatless, heated purge or heated blower purge: which one do I need?

Heatless is the simplest and lowest capital cost, and below roughly 150 SCFM it is almost always the right answer. Heated purge, like this XCHP, adds an external heater so the dryer regenerates on much less compressed air, and it starts paying for itself as flow and run hours climb. Heated blower purge goes a step further by using ambient air moved by a blower instead of compressed air for most of the regeneration, at higher capital cost and more moving parts. If you are near the crossover, send us your flow, pressure, run hours and electricity rate and we will run the comparison rather than guess.

How does the XCHP compare with the heatless XCHL?

Both are X-Series twin tower dryers with mounted filtration, NEMA 4 enclosures and Modbus-capable digital controls. The XCHL Series is heatless, costs less to buy, and has no heater to maintain. The XCHP costs more up front and gives most of that compressed air back. At 150 SCFM the gap is arguable; at 800 SCFM running three shifts it usually is not.

What happens if the heater fails?

The controller switches the dryer to heatless backup mode and continues delivering -40°F air on pressure swing regeneration alone. Purge consumption rises until the heater is repaired, but your air quality does not drop.

Do I still need to buy filters?

No. The prefilter and afterfilter are included and factory mounted on every configuration listed here. What you should not skip is a properly drained wet receiver upstream and diligent separator maintenance on an oil-flooded rotary screw. Oil is what kills desiccant.

What is the maximum working pressure?

150 psig. If your system runs above that, tell us and we will quote the correct platform instead.

What power does it need?

460/3/60 as standard, with NEMA 4 enclosures. 575V is a consult-factory configuration. We confirm heater rating and full-load amps with the factory for your electrical submittal before the unit ships.

Should I add the Energy Management System?

On almost any plant with variable demand, yes. EMS measures actual moisture loading and extends the drying cycle when the dryer is lightly loaded, so purge air and heater energy follow real demand instead of a fixed timer. It is the option that most often pays for itself, and it is the one customers most often wish they had specified.

What is the warranty?

The XCHP falls under Champion's X-Series warranty statement. Ask us for the current statement and for extended coverage pricing on your model.

How long does delivery take?

Lead time depends on capacity and options. Call us with your model and we will confirm the current factory schedule before you place the order.
