Universal Corrosion Resistance

Note: 9,9 mg/cm2.a = 32,5 μm/a and 0,2 mg/cm2.a = 0,65 μm/a considering S-SiC density

7



S-SiC Purity and Abrasion Resistance

• After initial cleaning

contamination rates drop

below 500 parts per trillion (<

500 x 10-12)

• Thanks to its extreme purity, its

corrosion and abrasion

resistance, S-SiC is highly

suitable for semiconductor

chemicals manufacturing and

pharmaceutical applications

(e.g peptides)

Note: particle contamination resulting from a S-SiC shell & tubes heat exchanger in a HF/H2O2 application

Shell & Tubes Heat Exchanger

• CORRESIC® SR

• Transfer area: 0.4 to 42 m² (4 to 450 ft²)

• Shell: ND 100 to 400 mm (4 to 16“)

• Tubes: Ø14/19 mm (OD ½“/ ¾“)

• Maximum temperature range: -30 to +220°C (-22 to +428°F)

• Max. pressure range: -1 to +10 bar (full vacuum to 145 psig)

10



CORRESIC® SR Compact Sealing System

• Compact sealing system with

double sealing as standard

> Minimized risk of cross contamination

• Sealing face in thermally resistant

cartridge

> no creeping at high temperatures

• No sinkings for sealing in tube sheet,

more compact bundling of tubes means

> up to 35% more transfer area

• Compression of tube sheets only by

outer bolt circle

> no corrosion risk

11



CORRESIC® SR Compact Sealing System

Sealing system before compression Sealing system after compression by the tube sheets

• Thermally resistant cartridge incorporates the sealing faces and

enables perfect sealing

• Use of gaskets with rectangular profile for highest sealing forces

• Easy replacement of tubes at discharged gaskets / compression plates

12



CORRESIC® SR Leakage Detection System

Tube sheet (assembled)

with leakage detection system

Spacer disc with collection / draining

channels and gasket

• The leakage detection system (optional feature) allows to

detect failing gasket in double sealing

13



CORRESIC® SE Block Heat Exchanger

• Monolithic blocks and headers in pressureless sintered

SiC material for universal corrosion resistance

• Modular design with axial bellow on shell side to

enable thermal expansion, helical springs for

homogenous sealing forces throughout the whole

range of operation, PTFE gaskets between the blocks,

and PTFE or stainless steel baffles on shell side

• Heat transfer area: 0,3 to 20 m² (3 to 215 ft²)

• Block diameter: 160, 260, 350 mm (6“, 10“, 14“)

• Temperature range: -60 to +230°C (-76 to 446°F)

• Pressure range: -1to +16 bar (full vacuum to 232 psig)

14



CORRESIC® SE Block Heat Exchanger

• Liquid / liquid heat exchanger or steam heaters for ultra-

aggressive applications (mixed acids, brines, and

organic solvents)

• Heater for stainless steel pickling bathes

• Acid concentration or stripping processes

Stack of S-SiC blocks
