Silicon Carbide (SiC) Heat Exchanger Blocks: Advanced Cross-Bore Heat Transfer Solutions

Product Description

Our Silicon Carbide (SiC) Heat Exchanger Blocks represent a breakthrough in thermal management for highly corrosive environments. Manufactured via direct isostatic pressing and pressure-free sintering, these blocks feature an innovative design of interconnected vertical and horizontal holes. This unique cross-bore configuration enables efficient heat transfer between two separate media while maintaining complete separation, making them ideal for the most demanding industrial applications.

Key Features & Advantages

• Superior Thermal Performance: Achieve exceptional heat transfer efficiency with a thermal conductivity rating of up to 140 W/m·K, ensuring optimal process temperature control.

• Unmatched Corrosion Resistance: Engineered to withstand the harshest conditions, including exposure to sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, and various mixed acids, significantly outperforming graphite and metal alternatives.

• Precision Engineering: Standard dimensional accuracy of ±1.0mm for hole size and ±0.1mm for wall thickness, with capability for custom finishing to meet even tighter tolerances per customer specifications.

• Robust & Reliable Design: Features integrated sealing waterlines for effective pressure sealing with compatible, corrosion-resistant materials. Each unit undergoes rigorous factory testing for guaranteed performance.

• Extended Service Life: The inherent material properties of Silicon Carbide provide exceptional durability, leading to a much longer operational lifespan and reduced total cost of ownership compared to traditional materials.
