ROBACERAM PressSaver

Combination of silicium-nitride ceramic and FRP base for an even dewatering profile.

Increased dewatering efficiency

• Increased open area - more than 65 %

Increased fabric lifetime

• Felt is not sucked into the slot anymore
• No stretching of the felt (less stress compared to "Z" design)

Decreased energy consumption

• Less vacuum is needed
• Less air consumption
• Less friction based on the good support

Special feature

Continuous ceramic surface for perfect support of the felt and reduction of friction

Application

Speeds of up to 3,000 mpm – fourdrinier machines for all positions under stress in modern paper machines (from gravitation dewatering)

ROBACERAM X-Ring Cover

Combination of plastic covering and ceramic elements specially for an even dewatering profile. Its unique barbed hooks ensure perfect fastening.

Higher dewatering capacity

• Larger open area - 65 % increase

Longer felt life

• Felt is not sucked into the slot
• No expansion of the felt (less stress than in the „Z“ design)

Reduction in the driving energy

• Less vacuum required
• Less air consumption
• Less friction due to good support

Special feature

Patented: Barbed hooks for guaranteed grip

Application

Felt suction covers in the press section

ROBACERAM Uhle Box Covers

Our covers offer unique safety features and the greatest useable thickness. To guarantee maximum safety, ceramic dewatering elements at Röchling Industrial are specially designed:

• Mechanical fixation of the ceramics at the FRP base body
• Mechanical segment fixation - no piano keying

Therefore different material qualities are available:

ROBACERAM-ALOX

• Proven material quality for over 20 years
• High purity of aluminium oxide (99.7%)
• Surface quality RA 0.3

ROBACERAM-ZIROX

• Special ceramic for press section
• Higher thermal shock resistance of 200°K
• Surface quality RA 0.2

ROBACERAM-SiN

• Thermal shock resistance of 600°K
• Better wear resistance
• Surface quality RA 0.1

ROBACERAM-PX

• Highest thermal shock resistance of 700°K
• Maximized wire lifetime
• Best surface quality RA 0.06 - reduction of friction and therefore reduction of drive power (energy saver)
