Design features

  • Tungsten carbide spray tip for maximum wear resistance and service life
  • Relatively coarse atomisation
  • The spray tapers slightly towards the outer edges, which makes the nozzle very suitable for applications where several nozzles are installed in line. By overlapping the spray of the nozzles, the result is an even spray across the entire line.

Choose the right spray nozzle for an optimised spray process

Each type of nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and type of solution.

The Knowledge base contains information about spray pattern, droplet size, flow rate/pressure, spray coverage, materials, etc. The 'Materials' section of the Knowledge base lists the most commonly requested materials and maximum temperature of the material.

Our main supplier is BETE, a leading manufacturer of spray nozzles and spray systems with more than 70 years of experience in spray processes and a product range including over 20,000 components.

BETE's spray technology is used worldwide to optimise processes in many different industries, including the energy sector, chemical and petrochemical industry, food industry and offshore.

Some of BETE's certifications include ISO 9001:2015, ATEX and FM Approval.
