Schmidt® SIGMA G-BLOC Graphite Block Heat Exchangers
Our SIGMA G-BLOC graphite block heat exchangers are ideal for use with corrosive materials, offer nearly universal corrosion resistance, and are the highest strength on the market. Made of modular, stacked graphite blocks with mounted PTFE seals between each adjoining block, the blocks are drilled in a specific pattern to optimize heat transfer through the graphite material.

How it works.
Corrosive medium flows through the axial process holes in the block
Service medium passes through the horizontal holes of the blocks, and flow is properly directed by special baffle cages
The complete unit is maintained under compression with a special STABLE LOAD® springs system
