GRAPHITE BLOCK HEAT EXCHANGERS

GRAPHITE BLOCK HEAT EXCHANGERS

Blocks heat exchangers from the Hykarb® and Polybloc® ranges are based on unique isostatic graphite by Mersen, Graphilor® 

Mersen has designed and manufactured block heat exchangers for over 50 years with more than 10 000 units in service in more than 50 countries.

Respectively named Polybloc® for the cylindrical design and Hykarb® for the cubic ones, Mersen's heat exchangers are based on Graphilor® 3, the only isostatic ultra-fine graphite.

They are used in fields such as: 

• Metallurgy: pickling bath, HCl, H2SO4, HF, HNO3
• Chemical: pigments, heat recovery on corrosive process, VCM, TDI, etc...
• Fine chemicals and pharmaceuticals

  Mersen graphite block heat exchangers are manufactured with its exclusive trademark graphite: Graphilor® 3, the only impregnated graphite resulting from the combination between isostatic graphite and a specific resin.
