Replacement level controls are available in both float and float free designs. The replacement assemblies are a reliable and cost effective solution for high maintenance pressure-powered pumps. They are designed to retrofit all major float-operated pump brands.

The float operated replacement level control incorporates an open-coil spring design, a reinforced float, and heavy-duty, high-cycle components.

The float-free replacement level control features a 2-probe conductance level control and a NEMA classified control assembly. This version has only one moving part to wear, no springs or floats, and easily provides remote monitoring capabilities. The float-free assembly features a bolt-on mounting flange that includes an externally mounted 3-way motive valve.

Logs can be fed either longitudinally from the end or transversely from the side with the wood axis parallel to the debarker axis.

Rotor Contact
Bond between bark and wood broken at the cambium layer by:

Contact with debarking plates
Log-to-log contact
As the rotors turn they bring the debarking plates into contact with the bark. This contact, along with the log to log contact within the debarking chamber breaks the bond between the wood and the bark at the cambium layer.

Inclined Plate
With other rotary debarker designs, the plate is installed without an incline. In the Fuji King Rotary Debarker design, the plate is oriented at an angle to the rotor surface rather than level with the surface. This design optimizes the angle of force imparted onto the log and promotes:

Optimal individual log rotation exposing more of the bark surface to the debarking plates
Optimal over-all log rotation within the chamber exposing more logs to the debarking plates

Electronic interface system vacuum controls provide complete vacuum control and integration specifically designed to optimize vacuum control valve performance. EIS allows pneumaticelectronic communication with valves to provide accurate and consistent control of vacuum levels. Using EIS, valves are linked to mill-wide DCS systems for optimum vacuum control.

Features and Benefits
Provides electronic communication with vacuum control valves that is more precise and faster than pneumatic valve controls
System responds immediately to changes detected in vacuum level supply or incoming sheet consistency to minimize variation
Remote vacuum setpoint adjustment for faster, easier, and safer vacuum adjustment
A single IP panel can drive several valves thereby reducing system complexity and cost
Systems can be configured for stand-alone closed-loop control or linked directly with mill-wide process control systems
