FUNCTION  

Our circulating type control unit is an automatic system to check consistency, liquid level and basic weight in one tank and it reacts rapidly on the change of input consistency and circulates continuously with new materials so there is no change on consistency and liquid level.
The consistency control ability is ±0.05% ( minor deflection may happens when there is a change on mixture of material and freeness ) with remote weight control unit so it is not necessary to go to distribution box or fan pump, which is with digital type to control weight from operation panel.  

   Automatic consistency control & recording system  

   To keep the consistency at fixed level by abstracting the consistency of materials and control the  valve automatically on the corresponding difference of consistency.

   Remote basic weight valve control system

   The unit is remote controlling the exact necessary materials for paper making machine. (gate valve)

   Automatic liquid level indicating and controlling system. (electronic type)

    Firstly, it controls the consistency as soon as possible to the indicated level by mixture of the circulated new material and the balanced material (approx.50%) after sending it to paper making machine through the  weight control valve.

   Circulating box (Circulating pump)

    To keep the constant supply of quantity for materials by mixing the material and dilution water in uniformity to control the weight and density.  

   EFFICIENCY OF CIRCULATING SYSTEM

It equalizes the density in vat and/or head box and also makes the quantity of vertical and horizontal direction in uniformity, and that the width of control is big due to automatic control of small change of quantity.
Improves productivity by equalizing the lower limit.
No trouble because it shortens the time to stay as the inspector and valve to be installed beside.
Possible to eliminate the pipes of overflow on the chest from vertical system.
Can save the energy from materials pump, and used machine chest can easily be eliminated.
Can save the time for substitution by confirming the modulation effect as it controls nearby the vat and/or head box.
Prevents lumping of additional materials so that expects improvement of efficiency.
The unit can control fastly and exactly on the density, water level and quantity inside of the circulating box (This is patented in Japan)
This way of density control system can control more exactly than 3 use of 3 units of old times style density controller.
