Tankrengöringsmaskin BETE HydroWhirl Orbitor 100 för kraftfull och effektiv rengöring av större tankar

TH - Hollow cone spray nozzle

TH is a tangential hollow cone nozzle with a large free passage. The nozzle generates a high impact, high velocity spray.

The TH nozzle can be supplied with a flange connection as an option to a thread connection.

TH är en tangentiell hålkonsdysa med stor fri passage. Dysan skapar en mycket kraftig spray, med hög velocitet. TH hålkonsdysa är tillverkad av BETE Spray Technology.
Illustration av hur sprayen skapas av en tangentiell hålkonsdysa. Den utgående sprayen är 90° i relation till ingångsaxeln. Spraybilden skapas genom att vätskan passerar en virvelkammare utan virvelinsats, innan vätskan lämnar utloppsmynningen. Sprayen är koncentrerad till den yttre delen av spraykonen.

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.
