Our approach

An industry where the material is everything

In chemicals, the same rotary dryer can be a perfect solution or a problem within weeks, depending on the steel it is built from. We work with a wide range of chemical products — acids, salts, resins, catalysts — and select the contact material from how aggressive the product actually is, not from a default.

Product catalogue

Some of the products we have processed

  • Boric acid
  • Ammonium sulphate
  • Potassium chloride
  • Sodium chloride
  • Dicalcium phosphate
  • Sodium nitrate
  • Catalysts
  • Resins
  • Polystyrene
  • Sodium metasilicate
  • Sodium tripolyphosphate
  • Sodium perborate

Material selection

The right material for each product

Stainless steels

For acidic or saline products that would attack carbon steel within a short time.

Linings and coatings

Where the product is aggressive but the cost of an all-stainless machine is not justified, we line only the critical contact areas.

Design for special atmospheres

Products that call for a controlled atmosphere, that must be kept away from oxygen, or that need protection against dust explosion risk (some of the products we process, such as certain nitrates and oxidising compounds, require exactly that).

Selection based on the actual product

Before settling on a material we analyse the customer’s specific product — we don’t assume that “potassium chloride” behaves the same way at every concentration and in every condition.
