9 questions to choose the right tank washing head

How is the tank to be cleaned made? What is the dirt to remove?

We already talked about choosing the right type of tank washing head, and its main applications in the past. But what are the practical questions to ask yourself before choosing a tank washing head?

The selection of the appropriate cleaning device involves multiple factors. However, if due consideration is given to the application, the process can be pretty straightforward. When selecting the cleaning device, consider the following with regards to the application at hand.

We collected 9 questions to ask to choose the right tank washing head. When selecting your cleaning device, it is essential to ask yourself these 9 questions to select the right solution:

What are the questions to ask yourself before choosing a tank washing head?

1

How is the tank to be cleaned made?

The size and number of internal structures of the tank or process vessel are significant in determining the type and quantity of devices required for its cleaning.

2

Type of soil to remove?

Why is it necessary to clean the tank or the canister? It might seem like a trivial question, but it is important to ask it to prevent cross-contamination, to decide whether to proceed with sterilization or for maintenance, product recovery, etc.
As a simple example, consider the removal of methanol versus the removal of latex.
We can remove methanol with a simple cascading of the fluid over the surfaces. A spray ball or rotating sphere could be employed, subject to tank size and capacity. However, in the case of latex, the cleaning process would take a long time if using a spray ball or a rotating sphere. For removing latex, it would be more effective to use a rotating jet-head.

3

What kind of surface needs to be cleaned?

The material of which the tank is made has its importance. Electropolished stainless steel and glass lined vessels are far easier surfaces to clean than carbon steel or certain types of coated tanks. The condition of the coating can also be a factor capable of influencing the performance of the tank washing head.

4

Is the washing for the food or pharmaceutical sector?

Sanitary cleaning devices, in most cases, are more costly and utilize more flow than a device that does not consider this requirement. If you require a 100% self-washing device, make it known in your cleaning design.

5

What openings are there in the system for installing the cleaning device?

In the case of of new equipment, this consideration is more flexible because a review of the vessel design can be made before construction and before determining cleaning requirements. In addition, installation is more accessible and usually less costly. Instead, in the case of existing equipment, the desired location for the cleaning device may not be available. This will have a bearing on the device selected and its operating parameters.

6

How much time can you devote to cleaning tanks?

Since production requirements are a primary factor, the speed at which the selected device or devices clean the tank should be considered.

7

Is it necessary for the washing head to be permanently installed?

The cleaning device can be different if portable rather than fixed placement is desired. For example, you may not usually require the device to be fully self-washing if it is to be installed only for the cleaning process and then removed.

8

What is the budget?

The cost of cleaning devices and their associated systems for a given application can vary. The purchase of the device is only part of the cost. In many cases, if the proper cleaning system and device are selected, operational savings can result in a favorable return on investment.

9

What are the operational parameters?

Pressure, flow rates, tank/vessel evacuation rates, cleaning media, operating and at rest temperatures of the cleaning device are all considerations in the selection process. These criteria determine, among others, the construction requirements of the device.
