DETAIL
Untapped thermal potential
If the compressor runs, but hardly any heat is removed, a consumer, a suitable control or sufficient operating hours on the heat side may be missing.

Why monitor?
What this parameter reveals about your compressed air station.
Flow rate and supply and return temperatures determine the heat actually transferred. This reveals whether the heat generated by the compressor is used in the heating or process system.
DETAIL
Detecting weak heat transfer
Too little temperature spread or falling thermal output can indicate a contaminated heat exchanger, incorrect hydraulics or too little water flow.
DETAIL
Detecting a lack of reconciliation
High return temperatures, frequent valve limitation or highly fluctuating decrease show that accumulators, pumps and consumers do not match the available heat.
In practice
Where the input energy goes.
Much of the electrical input becomes heat. Actual utilisation depends on temperature levels, heat consumers and operating hours.
