Substantial Order for Graphite

2020/8/26SGL Carbon received a substantial order for a tailor-made set of graphite-based heat exchangers of different types from a big customer in the US back in May 2020. The completely assembled systems will be used by the customer to expand its capacity for the production of phosphoric acid as one of the main raw materials to produce fertilizer for the agricultural sector worldwide.

Polymeric Hollow

Compared to metallic exchangers, these heat exchangers weigh much less, have an order of magnitude larger surface area per unit volume, and are likely to be considerably cheaper. Small polymeric heat exchange devices having an effective length less than 30.5 cm (∼1 ft.) achieve efficiencies close to 1, provide NTU values close to 4, and have HTU values as low as 5 cm.
