BWT Filter systems

BWT filtration systems are multi-purpose designs guaranteeing high quality water treatment for producing pure steam in combi steamers and other equipment working with water (regenerators, holding cabinets). This involves innovative water treatment for quality gastronomy and extension of the service life of combi steamers and other equipment.

  • Extension of the service life of the combi steamer and other equipment
  • Savings on costs for electricity and servicing
  • Premium quality water thanks to the new High-Efficiency-Technology (HET) high efficiency 5-level filtration.
  • Highly efficient protection from scale deposits.
  • Excellent protection against equipment corrosion caused by low-quality, aggressive water.
  • Ensures a constantly high pH value.
  • Streamlined design of water flow using a filter.
  • Use of high-quality filtration materials.
  • Maximal use of the entire filter.
  • Simple installation, putting into operation and filter replacement.
  • Complete connectors for all types / sizes of filters
