Principles​

​To produce the hygienic - clean and dry - wash item we apply;

  • physical impact (re-circulated water at different pressure throughout the washing process)

  • temperature

  • detergent

  • re-circulated air OR centrifugal force (when blow or spin drying newly washed crates)

  • time

Normally time is money, but with Sanitube this important factor of a thorough cleaning process is not where your money goes. The Sanitube design principle and the use of large diameter tubes to provide length and thereby process time makes the cost of going “the extra mile” an acceptable one. Did you notice how we have taken the numerous welding hours and amounts of stainless steel out of producing additional wash cycle time in terms of metres of tunnel and tank? The solid massive wall tube is the answer!

To convert tubes into washers Sanitube add and apply only well recognized quality components and from our list of suppliers we recommend e.g. APV, Bürkert, Grundfos, Spraying Systems and Unichain.

For re-circulating wash water and to keep consumption down Sanitube modules are equipped with different filter solutions depending on the job at hand. It can be a filter insert, a filter tray or a self cleaning rotating filter screw or all in combination depending on the specific cleaning task and the modules then combined to meet demands.

Furthermore the same process water is used over and over again in more modules and processes based on flow principles of how to minimise consumption of heat, water and detergent.

​Another “free” advantage of converting large diameter tubes into washers is the possibility of having large connectable tanks in the total length of each wash installation. This is something which the cylinder shape of the Sanitube provides for very well. Large tanks are importantwith sufficient volume and content not to re-circulate the desired amount of the same wash water to many times per hour. To much pressurized recirculation through pumps and nozzles ties air into the heated detergent added wash water. Pumping 100 m3 of wash water per hour on a 800 litre wash tank will recirculate wash water 125 times per hour with little time for it to "rest" and release air before recirculation and compression through pumps. Having a 3000 litre tank for the same wash job recirculates wash water only 33 times per hour for it to release air and by this to maintain wash water impact and efficiency. A washer designed with a small tank (to save on steel, welding hours and costs) can severely, and within just few minutes of running, compromise the effeciency and therefore the whole investment on the complete system even - and especially so - if fitted with large pumps to give the immediate but false impression of a effective wash process. A washer can be an expensive bought illusion if not dimensioned according to certain criteria evolving from years of experience in making such equipment. Or it can be a well balanced optimal running machine from the first push of a button and numerous years ahead.


So eventually small tanks and many recirculations done on the same amount of wash water (of course reusing this for environmental and economical reasons) make the physical impact of the wash water disintegrate then affecting the wash result over time. Therefore, large tanks and preferably connectable ones in the full length of the installation are recommended! Why do tanks then have to be connectable? For standard modules combined in your installation to be able to share pumps, filters, heating sources and detergent supply systems. Also of course tanks can be divided to accumulate heavy debris for instance in a pre-rinse or a label removing module.
