• Infrared Thermography in the Process Gas Plant
  Burlington Resources uses infrared thermography to inspect electrical connections throughout their process gas plant for predictive maintenance, greatly reducing plant downtime and unscheduled shutdowns, and thereby leading to the realization of huge cost savings. The thermography program is used...

• The Hidden Costs of Compressed Air/Gas Leaks
  reducing valves are relied upon to control the manufacturing process. Precise control is critical to the product we produce and to the indoor environments we seek to maintain. Air operated for heating and ventilating system needs to accurately control the heating and/or cooling process. For example...

  for corrosive applications and environments. It has inlet pressures up to 3600 psig; outlet pressures from 0 to 10, 25, 50, 100, 250, 500, or 750 psig; and a flow coefficient of 0.02, 0.06, or 0.20. With low operating torque and internal volume, the instrument can regulate high flows with only a small pressure...
