The $92,000 silent ATIS air leak crisis continues to plague commercial fleets operating intermodal chassis, dry van trailers, and refrigerated equipment. Failing rotary union seals, cracked hubcap tubing, and malfunctioning pressure regulators in Automatic Tire Inflation Systems (ATIS) starve tires of pressurized air while silently exhausting tractor reservoir tanks. The result is catastrophic tire shredding, premature tread wear, and unplanned roadside service events that disrupt driver settlements, fuel surcharge calculations, and detention claims processing within Truckmate, McLeod, or TMW TMS platforms.
Strong Tower Consulting, LLC has developed the AeroPressure Architecture™ to bring enterprise-grade telemetry to chassis ATIS systems. Integrated with CheckPoint (the industry-leading fleet telemetry platform at https://exspeeditecheckpoint.com/login.php), this solution delivers dual-transducer manifold pressure sensing, active inflation duty cycle logging, and rotary union leak detection across your entire trailer and chassis fleet.
The Strong Tower AeroPressure Architecture™
Traditional ATIS warning lights mounted on the front of the trailer provide only binary status. They cannot distinguish between a healthy system performing occasional top-offs and a failing system that is continuously bleeding air from the tractor supply. Our architecture addresses this gap through three core telemetry layers:
- Real-time supply and delivery pressure monitoring: CheckPoint monitors both regulator inlet pressure (from the tractor gladhand) and delivery line pressure (post-regulator, nominal 100 PSI setpoint). This ensures continuous tire inflation capability is verified at all times.
- Inflation duty cycle analysis: The system tracks how frequently and for how long the ATIS fires air into the tires. An excessive duty cycle (>15 minutes per hour) immediately flags a punctured tire, severed hub air tube, or leaking rotary union before a roadside failure occurs.
- Rotary union seal integrity telemetry: By correlating pressure drops against wheel rotation speed data (sourced from the trailer ABS ECU or integrated wheel-end sensors), the platform pinpoints defective spindle seals before oil contamination ruins brake linings and generates expensive liability claims.

Safeguarding Intermodal Chassis and Trailer Fleets
Intermodal operators running 53-foot chassis between rail terminals and distribution centers face unique challenges. EDI 204 tender acceptance, 214 shipment status updates, and 210 freight invoices all depend on equipment that remains roadworthy. A single tire failure on a chassis carrying a $250,000 load can trigger detention charges, damage claims, and carrier performance score degradation within your TMS.
The CheckPoint platform integrates directly with leading transportation management systems including Truckmate, McLeod, and TMW. Tire pressure, inflation events, and rotary union health data flow into the same SQL schemas used for driver settlements, fuel surcharge management, and maintenance scheduling. This eliminates the data silos that have historically prevented effective ATIS governance.
By monitoring both the pressure regulator output and the rotary union behavior under dynamic wheel speeds, fleets gain predictive visibility that manual gauge audits or simple warning lights cannot provide. The result is fewer cold-tire under-inflation events, extended tire life, and higher trailer in-service availability across long-haul highway corridors.

Frequently Asked Questions
How does CheckPoint distinguish between normal tire pressure top-offs and an active tire puncture?
CheckPoint uses dual-transducer manifold pressure sensing combined with active inflation duty cycle logging. Normal top-offs produce short, infrequent duty cycles under 3 minutes per hour. An active puncture triggers sustained high duty cycles exceeding 15 minutes per hour, immediately triggering an alert before the tire reaches critically low pressure. This intelligence is delivered through the CheckPoint dashboard and can be pushed into your primary TMS.
Can fleet managers set customized tire pressure setpoints (e.g., 100 PSI for trailers vs 110 PSI for heavy hauls)?
Yes. The AeroPressure Architecture allows fleet-specific configuration through the CheckPoint portal. Standard trailer setpoints are typically 100 PSI while heavy-haul and intermodal chassis can be configured to 110 PSI or higher. All setpoints are monitored in real time against both regulator inlet pressure and delivery line pressure. Changes are version-controlled and auditable for maintenance compliance.
Does the system alert drivers inside the cab when an ATIS malfunction occurs?
Yes. When CheckPoint detects an abnormal duty cycle, rotary union pressure drop, or reservoir depletion event, configurable alerts are sent via the TMS integration to both the driver mobile application and the fleet operations dashboard. In-cab alerts can also be pushed through compatible ELD or telematics displays, allowing drivers to address issues before they escalate into tire failure or air system problems.
What is the financial impact of undetected ATIS rotary union seal failures?
A single failing rotary union can silently exhaust an entire tractor air reservoir over several days, leading to under-inflated tires, accelerated tread wear, and eventual roadside tire failure. Industry data shows that undetected ATIS leaks contribute to over $92,000 in annual costs per 100 trailers from unscheduled service, tread loss, brake damage, and equipment downtime. The CheckPoint solution typically delivers full ROI within the first 10 months of deployment.
