   Fuel monitoring for organic heat transfer
   medias with traffic light signal

 

   Meaning traffic light function:

   green:

   Normal operation, no fault:

  • Display of the oil temperature in degrees Celsius [ °C]
  • Display of the thermal oil concentration in the measuring circuit in percent

   yellow:

  • Information on Display: Temperature in °C too low
  • Check control system

   red:

   Exceeded share of foreign media in the process medium

  • Information on Display: Silicone oil error
  • Check operating conditions and take appropriate measures in case of deviations from the permissible values

Fuel monitoring system "kontamaxx" for increased safety and lower operating costs in thermal oil systems

Organic heat transfer media offer the opportunities to transfer extremely high or low temperatures. However, some essential boundary conditions must be observed for a trouble-free and durable operation.

It is particularly important to prevent decomposition by oxidation or thermal overload by appropriate technical measures. Also, contamination with foreign substances can affect the properties of organic heat transfer media and lead to unplanned disruptions.

Such anomalies which could be caused by technical faults or operating errors have often considerable economic consequences by increased fuel or electricity consumption, increased refill quantities, failures, unplanned interruptions of the production, damage to equipment or injury to the heat transfer medium. In exceptional cases, by excessive damage to the heat carrier even fire risks can occur.

To avoid these risks, the kontamaxx fuel monitoring system for reliable monitoring of the condition of organic heat transfer fluids was developed.
The determination of the media properties takes place via a patented acoustic sensor which very accurately determines changes in any organic medium very exactly ± 0.1% by using the speed of sound, the acoustic impedance and acoustic attenuation. If parameters are differing from the normal it displays Alarm by traffic light.

Depending on the application, the measurement method is individually adapted and is available, on customer request, also for highly accurate moisture measurements with additional capacitive sensors.
