The complete guide to choosing the right tank washing head

What is the difference between single axis heads, twin axis heads and fixed spray heads? 

Tank washing heads are devices specially designed for washing industrial tanks. They can be classic fixed spray heads or even high-tech models such as single and twin axis heads.

How to identify the right washing head for every need?

It is very difficult to assess such value as the efficiency range with reference to a given tank washing device without taking into considerations the various parameters relating to the process conditions, such as the materials you have to remove, working temperature and pressure, the time of every washing cycle.

While choosing a tank washing head, you have to consider if:

  • the wetting radius is adequate for the dimension of the tank;
  • the capacity can provide the whole inner surface with a correct amount of washing solution for square measure;
  • the impact force of the jet and the time required to complete a cleaning cycle are adequate for the product and/or process.

Our long experience in the field of tank cleaning suggests that the following basic concepts are given proper consideration in order to determine the correct washing cycle for each single application, and consequently the most suitable type of tank cleaning device.

1 | PROPER FILTERING FOR THE WASHING LIQUID
Small inner passages and precision machined parts are typically found in tank washing equipment.
In such cases where the washing cycle is performed by means of a recycled solution the solid particles which may be dispersed into the solution must be characterized for dimension and properties. Since suspended solid particles may affect proper operation of tank washing equipment, or require more frequent cleaning or service of the same, we suggest that a suitable line filter be considered.

2 | CORRECT CHOICE FOR WASHING CYCLE AND SOLUTION
Based on the type of product which has to be eliminated, each single process has to be examined in order to define such parameters as the appropriate washing fluid, the right temperature, jet pressure and washing time of every phase.

3 | ADEQUATE MOTIVE MECHANISM
The number of products which need to be removed from the wall of a tank is near to endless, each one showing its own different properties.
Washing cycles can range from a quick water rinse at low pressure and ambient temperature, to long lasting cycles using hot water and caustic, sometimes at high pressure. The latter situation requires both a slow motion of the fluid jets, which have to hit the tank wall without breaking into drops and loose their impact, and a properly indexed rotation so that the revolving jets do not hit the same path at each turn.

4 | CLEANING RADIUS / WETTING RADIUS
It is not possible to define the cleaning radius of any tank washing equipment without making reference to precise conditions as the product to be eliminated, the cleaning fluid, the operating pressure and temperature. Such value can only be determined by experience, for each single given process.
It is instead possible to define a wetting radius, as the radius where the equipment can wet the entire tank inner surface: in this condition it must be expected the fluid to hit the wall with a small fraction of its original impact force.

What types of washing heads are available and why choosing them?

SINGLE AXIX HEADS

It’s a device where the moving part is rotating around the vertical axis of the feed pipe. They are more suitable to wash products with low resistance.

TWIN AXIS HEADS

The most sophisticated tank washing equipment, where high impact fluid jets slowly move with a combined rotation around one vertical and one horizontal axis.
The motive mechanism assures the jet to hit always different paths at each turn, so that each single point of the inner tank surface is surely cleaned..
