Raising the bar in the tank cleaning industry
If the tanker is not cleaned well, it can cause unspecified cross contamination and a broken traceability chain.
Tank operators and owners rarely have the luxury of dedicating their units to specific duties if they are to maximise asset utilisation and the return on their investment.
Inevitably, they are faced with cleaning between cargoes to return their units to full service as quickly as possible to a certifiable clean standard.
With the vast range of products stored and transported in tanks, this can sometimes prove to be a challenge.
Ideally, tank operators want to clean at the lowest cost with a cleaning product and process that will clean the widest range of dirt and soils in the easiest manner and fastest time possible.
Of course, not all soils are the same and some are notoriously difficult to remove, posing significant challenges to the industry. This is not helped when there is significant time between cleans and different cargoes.
Interior cleaning of transport, storage and production containers in the chemical industry can only take place efficiently in compliance with applicable standards and depending on individual conditions. Choosing the correct cleaning technology depends on the type of contamination, shape, and size of container, available access options and any components in the container. Cleaning with automated high pressure units in particular is now more widely used due to shorter production downtimes and related cost savings.
Cleaning is generally perceived as a necessary evil rather than adding any value. This is perhaps slightly unfair, but a point to be accepted rather than dwelled upon.
Cleaning of tank containers, wells, bins even chewing gum, graffiti, or even posters - the list of applications for high pressure and hot water equipment is long and extensive.
For more than 45 years, Waterkracht has put all its experience into the development and production of high pressure cleaning machines.
The Dutch company specialises in efficient and environmentally friendly cleaning solutions.
In the low, medium and high pressure segments, Waterkracht offers a wide range of products and customised systems.
The Dutch company offers tank washing heads that are supplied with detailed technical documentation including detailed exploded views and spare parts lists.
Every small spare part can be ordered individually upon request and the most common ones are organised into different kits for simplicity.
Some of the company’s most important tank interior cleaning devices are the RW series that includes the RW190A, the RW200A and the RW610A.
What all these heads have in common are their simple mechanical structure as well as strong standardisation.
Repairs and maintenance are very easy and quick and these tasks can be carried out without the use of specific tools.
In summary, the RW190A is a specialised cleaning tool that operates with water or cleaning solutions at high pressure and flow rates.
It is made of stainless steel and it does not require an external drive while it has certifications for hazardous environments.
It is primarily used for cleaning tank trailers, but can also be used for IBC containers.
The head operates at the maximum pressure of 150 bar and with a flow rate of 60 litres per minute, which it can easily handle.
The RW190A is equipped with an aquamotor, which is a type of motor that operates without the need for oil and lubricants.
The RW200A, on the other hand, can operate at a maximum pressure of 200 bar with a flow rate of 200 litres per minute – thus generating high pressure water flows for cleaning purposes. It is also equipped with an aquamotor.
The device is constructed using AISI 316, which is a type of stainless steel known for its excellent corrosion resistance.
This material can withstand harsh cleaning environments, while maintaining durability.
It is primarily used for cleaning standard ISO containers that are 6 metres long and have a manhole located in the middle.
The device also holds a standard certification for Atex Zone 0 – the European Union directive for controlling explosive atmospheres, with 0 being the highest risk zone.
The RW610A can operate at a maximum operating pressure of 10 bar and it can provide a flow rate of up to 600 litres per minute.
It is primarily used for circulation cleaning of standard ISO containers and dues to its special construction, it has no seals.
Besides water, it can also be operated with pure latex solvent or even diesel.
The device is also made from AISI 316 stainless steel. The RW610A is designed to be used with openings or access points that have a minimum diameter of 472 mm.
