Accessories for Suction Pressure Roll
Water Channel with Double Body DST Doctor
Improves significantly the press efficiency increasing the water removal from suction roll surface reducing paper web rewetting.
Double body DST doctor also ensures a more homogeneous water removal on cross direction, improving the paper web moisture profile.
Steam box
Increases the after press dryness
Allows the reuse of the flash steam from the Yankee cylinder and hood resulting in energy savings
Very useful operating combined with both, suction press rolls and blind drill press roll
