CORRESIC® silicon carbide block heat exchangers are adapted to the heating, cooling, evaporation, condensation and absorption of highly corrosive and/or oxidizing chemicals. This design is one of the most versatile type of silicon carbide heat exchangers. Rows of holes are drilled through the silicon carbide blocks both horizontally and vertically to form the process and service channels. Heat is transferred by conduction through the silicon carbide left between the rows of holes which separate the mediums being used. SiC block heat exchangers consist in a stack of blocks encapsulated in a steel shell.
A block heat exchanger is a device which transfers heat from one medium to another without direct contact between fluids. For material properties, cost and efficiency reasons block heat exchangers only exist in silicon carbide and impervious graphite. Rows of holes are drilled through the blocks both horizontally and vertically to form the process and service channels. Heat is transferred by conduction through the exchanger material left between the rows of holes which separate the mediums being used. Silicon carbide blocks are cylindrical. SiC block heat exchangers consist in a stack of blocks encapsulated in a steel shell.
The thermal performance of block heat exchangers can vary significantly. It is therefore essential to select the type and size of block heat exchanger that is the most adapted to the specific application and industrial process. There are a number of considerations including flow rate, pressure drop, risk of erosion, design pressure and temperature, materials compatibility, fouling, and many more that should be taken in account.
GAB Neumann’s silicon carbide block heat exchangers are designed to cool down, condense, heat up, evaporate or absorb ultra-corrosive chemicals. Safety, reliability, and performance on the long-term are our primary considerations when we size, design and manufacture our SiC block heat exchangers.
Our extended and highly customizable block heat exchanger portfolio enables us to provide particularly adapted solutions to ultra-corrosive heat transfers. All our cylindrical block heat exchangers’ designs are totally modular to best fit with individual process specification. The number and size of blocks, the number and diameters of holes as well as the number of passes both on process and service sides can be adapted to best meet the velocities, pressure drops, and heat transfer requirements.
They can be fitted with all kinds of optional features such as sight glasses or demountable headers to better fit the process requirements.
All our SiC block heat exchangers are machined before sintering thus guarantying a smooth heat transfer surface and ensuring their outstanding corrosion resistance.
