SHINEHEAT PLATE HEAT EXCHANGER APPLY FOR CAUSTIC SODA COOLER
 

Shineheat plate heat exchanger apply for Caustic Soda Cooler
 
In Chlor-alkali chemical plant, the Caustic Soda Solution need to cool or thermal recycle during the production process. Plate and Gasket Heat Exchanger or Welded Plate and Frame Heat Exchanger play the important role during cooling or heat exchanging process.
In order to make qualified products, the Caustic Soda Solution need to reach specific temperature range. This job is definitely implemented by High efficient Plate type heat exchanger.
 
Now Shineheat offer a Plate heat exchanger as Caustic Soda Cooler at Chlor-alkali plant.
Following is design data sheet of plate heat exchanger.

Plate Material: 0.6mm Nickel 201 Plate
Gasket Material: EPDM

 
In view of High Corrosive feature of Caustic Soda, we use 0.6mm Nickel 201 material sheet as Plates. The Nickel 201 raw material comes from Nippon of Japan, the Ni Composition is 99.5%. Furthermore, Shineheat’s procurement is all Positive Allowance in Nickel plate thickness, generally in 0.65mm before pressing. It is contribute longer service life for Shineheat Plate Heat Exchanger.
 
By many years’ supplying experience in Chlor-alkali industry, we design optimal model of plate heat exchanger by both thermal efficiency, pressure drop and size economical, also take future capacity expansion into consideration, so you will find our enough length in Carrying and Guarding Bar of plate heat exchanger.
