Quality
Refiners widely acknowledged by the market due to their quality and efficiency
Extended refiner useful life due to high mechanical ruggedness and all parts in contact with the pulp made in stainless steel.
Low Operational Cost
Excellent refining performance with assisted control of the refining energy used, via a PLC programmed for this application
Application
Equipment designed for applications with low consistency (up to 6%) and able to operate in stock preparation or in approach flow systems.
Safety
Electronic and mechanical safeguards that increase operator safety in compliance with the highest Safety Standards
Operation Management
Power assisted control of refining energy, with a PLC dedicated for this application
The system also allows real-time monitoring of bearing temperature, sealing water pressure and stock inlet and outlet pressure
Spline Shaft System
Eliminates the axial movement of main shaft
No sliding coupling needed
Removes all main Shaft movement devices
Reduces the main shaft natural wearing
Improves the gasket sealing avoiding stock leakage
Increases Refining plates lifespan
Refining Optimization
Our field team carries out surveys related to the process and the refiner installation; besides that, it evaluates the equipment conditions
Based on all information collected, we offer technical guidance for improvements in the process that targets energy savings, reduction of water consumption and eventually improvements on fiber treatment
This can be done on installations with Hergen refiners as well as on installations with refiners from different brands
