Hum and Lexair Partner to Create
Sensor Technology for Coal Shippers

Hum and Lexair Announce Exclusive Partnership Agreement to Bring
Next-Generation Sensor Technology to Railcar Owners

St. Louis, MO: Hum Industrial Technology, Inc. (“Hum”) today announced a new partnership with Lexair, Inc. This partnership will bring wireless sensor technology to pneumatic valves on bottom discharge railcars to provide a next-generation safety solution. This technology will assure the correct operation and proper position of the discharge gates preventing unwanted or unexpected operation or discharge of the car.  


“We’ve been working with Lexair and their customers for some time now to develop this technology and are excited to finally announce our partnership in delivering a solution to monitor and help eliminate the issue of bottom discharge gates that open unexpectedly,” says Byron Porter, CEO at Hum. “Having personally experienced how dangerous rail work can be, I’m pleased we’ve created a complete solution with Lexair to solve a dangerous safety issue that has plagued shippers and railroads for some time.” 



“We are excited to be working with HUM and their available technology to help provide another layer of operational and safety related enhancements to our Second Generation Valves,” says John Jennings, V.P. of Sales and Marketing for the Valve Group at Lexair. 

The benefits of this new partnership include:

  • Lexair will be the sole distributor of Hum’s ValveSense sensor, specifically designed to work only with Lexair’s Second Generation Railcar Valves.
  • The Hum wireless monitoring system combined with Lexair’s patented valve locking mechanism enables railcar owners and operators to know whether their Lexair valves are locked or unlocked anytime, anywhere.
  • Geofence-triggered reporting and automated email alerts from Hum’s monitoring system provide rail shippers and operators with immediate notification when a valve changes from a locked to unlocked state or when it is never properly locked.
