Clip dryers
Manually operated waste air flaps in the drying tunnel are a thing of the past.
Nowadays, a sensor measures the relative humidity. This is regulated by a frequency-controlled waste air fan. With the automated residual moisture measurement of the leather at the end of the drying process, the product is prepared in the best possible way for subsequent finishing.

Waste air volume control: ECO VAC model
When the modern infrared radiators in the dryer are in operation, a certain volume of waste air is required to take away the vaporised water (H2O) that forms during drying.
In the waste air duct, a sensor measures the relative humidity of the waste air. Frequency-controlled waste air fans regulate the waste air volume to keep it in the optimal range according to the preselected relative humidity.
Residual moisture measurement: Moisture Matic model
On leaving the drying tunnel and the cooling system, the sensor measures the residual moisture in the leather at various points along a conveyor belt. The current residual moisture measurement and the average residual moisture of the piece of leather can be seen on the display.
