Our manufacturing system and materials.

Salher’s manufacturing system provides complete water-tightness, corrosion resistance and the flexibility to build shapes and designs according to the project requirements.
  • We have an exclusive molding system by filament winding, and a simultaneous projection molding for the manufacture of our GFRP (glass fibre reinforced polymer) boiler.
  • We use several types of stainless steel (AISI304 and AISI316), which are found in our robust, lightweight and highly durable equipment.

  • We use plastic materials such as high density polyethylene (HDPE) and polypropylene (PP) to achieve compact, high-strength equipment with thermal and chemical stability.

Quality control.

We perform a systematic control of the manufactured products, selecting the appropriate processes and raw materials. Salher manufacturing and designs are certified in accordance with the ISO 9001:2008 Standard.

Other products such as hydrocarbon separators and wastewater treatment plants are certified EN 858 and EN 12566. The structural strength, chemical resistance and hydrostatic test are certified EN 976 and EN 858.
