SSiC silicon carbide outperforms tantalum, titanium and Hastelloy
SiC block heat exchangers are an alternative to heat exchangers made of tantalum, titanium or Hastelloy because of their many advantages. They also outperform PTFE-impregnated graphite heat exchangers and SiC tube bundle heat exchangers fitted with O-rings. Due to their superior performance and durability, they pay for themselves in a short time.
Silicon carbide block heat exchanger
Wilk-Graphite silicon carbide block heat exchangers are manufactured from pure, directly and pressureless sintered SIC blocks (SSiC). They do not contain any free silicone, which could reduce the chemical resistance. Therefore SSiC offers an almost universal chemical resistance with highest thermal conductivity. In addition, the extreme surface hardness protects against abrasion and enables high flow rates with maximum thermal efficiency.
Extreme thermal conductivity is superior to metallic conductors
The extreme thermal conductivity of SiC means that a SiC block heat exchanger with Ø 300 mm achieves the performance of a graphite heat exchanger with Ø 600 – 800 mm. It thus exceeds the thermal conductivity of all metallic materials.
To optimize the service life, the SiC block heat exchangers are designed to be self-cleaning.
