Surface protection details

The unit is steel-blasted inside and out, in accordance with DIN 50 049 and Swedish standard Sa 2,5.

  • The first protective layer is applied in airless spraying inside and outside; the minimum thickness of the coating is nominally 150 µm thick. This special anti-corrosion paint is solvent free and provides a very high degree of corrosion protection (contains zinc and phosphate).
  • The second protection layer of coating is at least 150 µm thick. This coating is a pigmented, solvent-free liquid plastic of high elasticity at all practical temperatures.
  • The unique two-layer polymer coating on the steel shell is rated for at least 20 years of corrosion protection that would result in leakage. The integrity of the system is electronically monitored.
