LG41 VacuTouchIt is a control system from the TOUCH series, equipped with a special multi function sensor (LG35 – Timber / Air moisture, Timber / Air / Plates temperature, absolute pressure) for the management of vacuum based kiln dryers. The system automatically manages all the functions of the kiln and it can be adjusted to fit on different kilns, with single and double chambers, with or without drain tank, with or without humidification / dehumidification systems, for discontinuous vacuum or plates heating.

In the systems operating with discontinuous vacuum, the system can be set to automatically switch from continuous to discontinuous vacuum on basis of the measured values. The drying cycles can be defined in order to automatically change the climatic condition with the progress of the drying cycle, but it is still possible to define time-based phases. All the devices of the kiln can be driven in automatic or manual mode, simply by touching the related icon on the synoptic view. In the same way, every regulation parameter can be calculated on basis of the running program as well as it can be changed "on the fly", simply touching the displayed value on the screen.

The system can also be equipped with wireless sensors for the timber temperature and moisture, especially useful with cart loading systems, where the traditional sensor cables could result not handy.
