The device automatically switches off such equipment after a pre-defined period of machine inactivity, provided there is no paper waste that needs to be extracted.

When waste has accrued and the machine is needed in operation again, sensors on the Hunkeler device detect the waste and restart the machine.

The time period can be specified and adjusted by the user to best suit the application. In the case of multiple ducts, temporarily inactive ports are automatically closed by gate valves.

The energy-saving system offers additional savings: extraction system performance is dynamically regulated as a function of the accrual of paper residues.

According to the company, users can significantly reduce their power consumption, cut the number of maintenance cycles and extend the life of extraction and compaction equipment.

Managing director Kurt Käser said the system delivered savings of up to 60%.

Additionally, Hunkeler integrates its extraction and compaction systems into heat recovery systems. Thanks to intelligent control of the air exchange, energy-efficiency can be greatly improved and overall operating costs further reduced.

Hunkeler says savings of up to 60% were achievable through using the system
