The Global Leader in Tire Inflation
 SINCE 1993. 

ATIS - "The Original Inflation System."

Since 1993,  P.S.I.  has become synonymous with Automatic Tire Inflation Systems (ATIS).  

When people THINK about ATIS they SAY P.S.I.  

THINK Proven ROI:

Paybacks for most Fleets in less than one year. 

 

THINK Extended Tire Life:

Under-inflation results in increased and uneven wear. 
By maintaining tire pressure at all times, ATIS by P.S.I. can extend tire life by 10 percent.

 

THINK Increased Fuel Economy:

According to a Federal Motor Carrier Safety Administration (FMCSA) study, ATIS by P.S.I. increases fuel economy by an average of 1.4 percent

 

THINK Reduced Maintenance Costs:

Tire manufacturers recommend checking tire pressure at least twice a month,
but with ATIS by P.S.I. tire pressure is maintained whenever your equipment hits the road.

 

THINK Improved Safety:

ATIS by P.S.I. significantly reduces the risk of tire blowouts and the potentially costly and dangerous consequences. Moreover, the Standard ThermALERT™ wheel-end heat sensing technology helps prevent wheel-end failures from heat build-up.

 

THINK Fewer Roadside Assistance Calls:

Tires are the top reason for costly service calls, many of which can be attributed to simple under-inflation.
ATIS by P.S.I. virtually eliminates those calls.

 

THINK Fewer Tire Violations and Fees:

The FMCSA monitors tire conditions and can impose fees on fleets that operate trailers with unacceptable

tires. ATIS by P.S.I. significantly reduces the risk of such fines.

ATIS - How it Works.

 

ATIS - World-class Components.

  A   P.S.I. Control Box

The patented "heart" of the system, the Control Box is factory set to your specifications, and with no moving parts can provide years of trouble-free service.  Air from the trailers's air tank is fed into the Control Box, filtered for impurities and then fed to the trailer axle(s) through DOT-approved air lines.

  B   P.S.I. Air Lines & Fittings

The Pressure Protection Valve (PPV) attaches directly to the trailer air tank to supply air to the ATIS.  It is regulated to turn off at 80 psi, ensuring the at the braking system has top priority in terms of air supply.

DOT-approved air lines and push-to-connect fittings make for an easy and efficient installation.

  C   P.S.I. Press Plug
with Standard ThermALERT™

The Press Plug is installed into the wheel ends (on hollow axles), and with the addition of the remaining ATIS components, essentially transforms the axle into an air chamber.  P.S.I.'s patented ThermALERT alerts you to elevated wheel-end temperatures.  If the temperature of the wheel-end elevates into a dangerous operating zone, the eutectic screw installed in the press plug will melt causing pressurized air to vent through the hub cap tee vent.  The Warning Light which is visible in the Driver's rear view mirror, allowing the driver to pull over to avoid a catastrophic event.  Air escaping through the hub cap vent will audibly identify the problem wheel end.

  D   P.S.I. Stators Tubes

The Stator is installed into the Press Plug to accept the Thru-Tee ​when it is installed thru the Hub Cap.  A Particulate Filter ensures no contaminants are introduced to the systems.

  E   P.S.I. Thru-Tee

The only moving part in the P.S.I. ATIS, the rotary union Thru-Tee is threaded through the Hub Cap and ​into the Stator.  This allows air to flow from the pressurized axles, through the Tire Hoses and into the tires.

  F   P.S.I. Tire Hose

The Tire Hose is the final connection.  A highly-engineered component and integral piece of the ATIS system, our proven hose composition and quality manufacturing process ensures long-lasting performance in a variety of conditions.

P.S.I. Check Port (CP) Tire Hose

The available Check Port (CP) Hose allows you to check tire pressure instantly with a gauge or easily add P.S.I.'s TireView® TPMS Sensors for complete tire visibility in-cab or via P.S.I.'s TireView® LIVE™ telematics portal -- we can even integrate with your existing telematics provider!

  G   P.S.I. Warning Light

The Warning Light mounts to the front of the trailer using the supplied harness.  It alerts the driver of a low tire or wheel end thermal event via P.S.I.'s patented ThermALERT.  If the temperature of the wheel-end elevates into a dangerous operating zone, the eutectic screw installed in the press plug will melt causing pressurized air to vent through the hub cap tee vent.  The Warning Light which is visible in the Driver's rear view mirror, allowing the driver to pull over to avoid a catastrophic event.  Air escaping the through the hub cap vent will audibly identify the problem wheel end.
