Moisture in the air system can compromise brake performance. Williams pointed out that multiple TMC sessions this week are devoted to air dryer systems. If left unchecked, moisture leads to frozen lines, increased downtime, and costly repairs. So the Haldex product line provides an “immediate offset” in terms of ROI, both from a projected two-year service cycle and improved performance.
“Think about the hourly cost of a maintenance person doing the work, the replacement part, the sheer downtime,” he said. “That starts adding up real quick.”
The new ApolloSDx air drying system is an advanced solution engineered to deliver clean, dry air to maximize braking performance. This system integrates proven Haldex air drying technologies to enhance efficiency and reliability.
At the core of the ApolloSDx is the Consep (condenser/separator) and the PURest Air Dryer which features an integrated purge volume, eliminating the need for a separate tank. The Consep pre-treats incoming air, removing up to 90% of contaminants before it reaches the PURest Air Dryer, according to the manufacturer. This process extends the life of the Multi-Treatment Cartridge (MTC+), which will remove up to 99% of any remaining moisture in the compressed air, providing superior protection against corrosion, freezing, and component failure.
The air dryer line is designed for installation by the OEM or is retrofittable. Of course, very little in the aftermarket CV space is simply plug-and-play. Williams emphasized the meticulous process behind fleet retrofits, including creating videos and extensive documentation.
“We'll work with the with the fleet and figure out the best possible options. We all know that every commercial vehicle is different,” Williams said. “We've got technicians that go out and will help identify the best possible place placement for those dryers. Our technicians are top notch; by the time it's mounted, it looks like it came from the OE.”
Indeed, the ApolloSDx features a compact system design optimizing undercarriage space for flexible mounting and easy maintenance. A preassembled system on a custom mounting bracket enables quick installation, with the Consep positioned on either the left or right side to accommodate vehicle configurations.
The PURest Air Dryer, with its integrated and easily accessible components, simplifies servicing the dryer which translates to reduced maintenance time. Changing the MTC+ cartridge requires only ½" of vertical clearance above the canister housing, making for easy service replacement.
The ApolloSDx configuration delivers up to 34 SCFM, filtering and drying air to extend the life of downstream components. By eliminating unnecessary fittings and tubes, Haldex enhances system reliability by reducing potential leak points.
