BPHE - Brazed Plate Heat Exchnger - corrosion resistance

Corrosion resistance of copper and nickel brazed plate heat exchangers

 
 Copper brazed plate heat exchangers are suitable for the following media:
  - Oils, glycol, alcohol, air, water, refrigerant and many more according to the material resistance
  - Group 2 fluids to the Pressure Equipment Directive 97/23/EC

 Copper brazed plate heat exchangers are not suitable for the following media:
  - Silicone oils, deionized water, seawater, strong chloride media, NH3, and strong acids and bases
 
- Explosive, strong, flammable, highly toxic liquid media from the Group 1 of the
    Pressure Equipment Directive 97/23/EC

      Ingredients allowed for water.

 A high calcium content leads in time deposits and can clog the heat exchanger.
 Copper-brazed plate heat exchangers may not be used with galvanized pipes.
 For applications with deionized water, ammonia, and silicon oils are nickel brazed plate heat exchangers
 recommended. For chlorine-loaded applications, such as swimming pools is the material AISI 316L with higher
 corrosion resistance and nickel as solder recommended.
