Cleaning/Washing Nozzles: Tanks, Vessels, and Processing Equipment

Cleaning/washing of storage tanks, process vessels, reactors, and processing equipment to remove residues and contaminates.


Tank washing is an important job in many industrial applications, and can be time-consuming and expensive without the correct solution for the given application. Storage tanks, process vessels, reactors, and process equipment can vary significantly in scope and size across all industries. However, almost all of these tanks must be cleaned before and/or after use to ensure sanitation and prevent product contamination.

Spray nozzles can help to maximize the efficiency of washing applications by ensuring proper distribution of the cleaning media and/or maximizing impact from the available flow rate/pressure of the system, reducing operating and disposal costs. They can offer significant time and money saving over other cleaning options such as "fill and drain" or manual entry (especially in hazardous environments). There are several types of tank washing nozzles available that can help to efficiently use the resources available to meet the specific application conditions and requirements.

Selecting a Tank Washing Nozzle:

Important factors to consider:

  • Type of tank washing nozzle to be selected

    • Static spray nozzles: these nozzles remain stationary and distribute the cleaning fluid through multiple nozzles, or other directional means (i.e. spiral). Without any moving components, these style of nozzles are typically durable and clog resistant, providing reliable operation and long service lives. However, as they must distribute the cleaning fluid over the entire target surface at once, they generally require the largest flow rates and provide the least amount of impact in washing applications.
    • Rotating spray balls: these nozzles use spinning heads that rotate and are generally driven by the reactionary force of the cleaning liquid leaving the head. As these rotating spray balls concentrate the spray media into smaller fan patterns and rotate these around the tank to provide complete coverage, they are significantly more efficient and use comparatively a much smaller amount of cleaning fluid or less cleaning time than static nozzles. Some reaction force nozzles are free-spinning while others rotate much more slowly.
    • Tank cleaning machines/rotating jet nozzles: these tank cleaning machines use concentrated cleaning jets or fans that rotate within two planes to provide a complete orbital spray pattern for tank cleaning. These nozzles are generally driven by the cleaning liquid flowing through an internal turbine or gear which rotates the nozzle at a controlled speed but some models may also use an electric or pneumatic motor to provide/control the necessary rotation. The concentrated spray jets utilized by these styles of nozzles maximize the impact force from the available flow rate/pressure and are ideal for large tanks requiring significant throw lengths from the nozzle and/or cleaning difficult residues such as peanut butter, BBQ sauce, paint, glues, resins, and etc.
  • Tank/vessel size and shape

    • Available nozzle placement/mounting positions
    • Internal vessel components (mixers, baffles, down pipes, etc.)
      • Potential to cause " shadow" areas by blocking spray
  • Application details and requirements

    • Residue to be removed
      • Rinsing
      • Soluble with water, soaps, detergents, or other chemicals
      • High impact washing required for removal
    • Temperature and chemical composition of wash fluid
      • Required materials of construction for corrosive residues and spray media
    • Closed vs. open top vessels
    • Permanent (CIP) vs portable installations
    • Required surface finish
    • Potentially explosive environments (ATEX)
  • Available/required flow rate

    • Achieve effective washing while minimize costs of treating or disposing of wastewater
  • Available pressure drop (∆P) across the nozzle

    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
