Saving energy at the dryer

Saving energy at the dryer

Definition. How precise inline measurement cuts gas consumption by 5-15 %.

Dryers are often run conservatively in practice — setpoint well above target drying so that final moisture is correct even with varying material.

With density-independent inline moisture measurement at the dryer outlet, the setpoint can be moved closer to the target value. Typically 5–15 % lower energy intake.

For a 200,000 m³/year MDF line, 10 % energy savings quickly add up to six-figure amounts per year.

FAQ

How fast does it amortize? +

For medium lines typically 9–14 months, depending on energy price and line throughput.

Practical tip

Need concrete help for your line?

Three data points — material, temperature, position — are enough for a first sensor recommendation.
