Rotajet caters to medical applications with the AMB 2000 machine that is designed to sanitise and decontaminate a range of medical equipment, including; wheelchairs, stretchers, and gurneys.

Whilst offering a comprehensive and quality cleaning solution to washing medical equipment, the Rotajet AMB 2000 takes the manual labour out of the cleaning process. On top of this, the optimised use of water and wash chemicals means that operational as well as labour costs can be kept to a minimum.

Historically, medical equipment used in ambulances for the transportation of patients would be sprayed down using jet washers and strong detergents. Whilst being an ineffective and inefficient way to decontaminate equipment, this process is also extremely labour-intensive and can be harmful to the environment.

With the repeatable medical-standard of cleaning offered by the AMB2000, you can be sure that your operation will be achieving the highest level of cleaning every time. For more information on Rotajet’s Sanitation equipment, get in contact with our dedicated team of experts. 

Rotajet’s range of Ultrasonic Cleaning Equipment offers the ideal solution to the contamination removal and sanitation of components. With the best quality of cleaning, these machines are used across the world for their safe and non-destructive removal of grease, dirt, and oils, as well as a range of other various surface contaminants.

In the first stage of cleaning, parts are submerged into the wash solution. Depending upon the specific application and contaminants present, the wash solution used can be either solvent-based or aqueous to provide the best quality of cleaning.




In the next stage, the wash solution is agitated using ultrasonic soundwaves in order to enhance the removal of unwanted contaminants and increase the speed and efficiency of the operation. These soundwaves are typically kept within the high-frequency range of 20-40KHz which cannot be heard by the human ear. At this level, the soundwaves will begin to create cavitation bubbles, resulting in the increased pressure and thus promoting the stripping of contaminants from the product.

Rotajet’s range of Ultrasonic Cleaning Equipment incorporates both standalone and fully automated, Multistage Systems that can be integrated into an existing production line. For larger operations, the multistage system can offer a significantly increased throughput rate, whilst ensuring that the manual handling of equipment is kept to a minimum.

Rotajet’s range of swarf recycling machines are design to reclaim high vale metals and superalloys from the machining process. Swarf or turnings represent a significant loss of material during the manufacturing process, leading to high quantities of waste from production. By turning this waste into a high-quality commodity, companies can begin to reduce their waste whilst also turning a profit from scrap metals.

With two standard, specialised systems, Rotajet has developed swarf washing machinery that is ideal for use in the size reduction, decontamination, and drying of the material; creating a vacuum-grade standard of raw material for resale into the market.

Due to the typically high value of swarf metals, such as titanium and nickel-iron-cobalt, that are often produced from production lines, the process of recycling can be an extremely lucrative one if done correctly. That’s why Rotajet’s RJ-RDW and RJ-RPW are designed to take care of the entire recycling process from start to finish.

When it comes to parts and components cleaning, there are two main options to consider; manual or use of an automatic spray washing machine. One of the major distinguishing factors between the two options is undoubtedly the price, but the other major factor is the quality of the cleaning standard that is achieved. 

Another thing to consider with manual cleaning and degreasing, however, is the numerous risks that would not otherwise be present with spray washing machine. The hazards involved can be related to several different factors, including; using harmful chemicals and cleaning detergents, handling sharp objects, and electric shocks.

Selecting the right chemicals to use when manually cleaning is paramount to not only achieving a good cleaning standard but to ensuring that the part or components subject to being cleaned will be exposed to chemicals that could be potentially corrosive or otherwise detrimental to their material structure. For example, where high pH cleaners like aqueous alkaline might be effective in cleaning stainless steel components, the same chemical may cause wear, discolouration or etching to aluminium parts. 

More importantly, when cleaning with chemicals, it is crucial that measures are taken to ensure the safety of any individuals who may be exposed. While exposure can refer to the direct use of the chemicals, the vapour given off can also represent a major risk to humans. To rescue risks such as these, there are a number of ways in which to ensure maximum protection when washing with potentially harmful chemicals, including:

● Keeping the environment well ventilated, e.g. by opening windows, using extractor fans, etc. 

● Wearing protective and waterproof clothing and goggles to avoid direct contact with the skin and eyes 

● Regularly washing hands and maintaining general hygiene 

● Use sealed proprietary equipment as opposed to open containers of cleaning solvents/chemicals 

● Avoid any open flames or intense heat as cleaning chemicals are often highly flammable 

How to Reduce Risk Factors

While the use of cleaning chemicals and detergents introduces major possible risks to manual cleaning and degreasing, there are other potentially hazardous factors that should equally be reduced at all costs. Some of the ways in which to reduce these risks include;

● Ensuring that any electrical equipment used has been fully tested and regularly maintained.

● Wearing protective items to avoid contact with sharp objects e.g. goggles, gloves, full-length clothing, etc.

● Keep temperatures of cleaning agents and environments to a low level that will not cause harm to humans. 

If high temperatures are used, ensure that precautions are taken to avoid direct contact with heat, such as; maintaining a far distance, wearing heat-proof clothing, etc.

Potential hazards are not the only thing to note when considering manually cleaning parts and components. For example, manual cleaning can use a considerable amount more energy, water, and detergent than machine washing. On top of this, the labour involved with manual cleaning is mountainous when compared to machine washing which, in a workplace setting, can increase costs by a significant amount, not to mention having potentially harmful effects on mental health. 

The major thing to note when opting for manual parts cleaning as opposed to machine washing is the significantly lower standard of overall cleaning quality. A much higher standard of cleaning can be achieved with a machine spray washer for a number of reasons, including; 

● The consistent and repeatable cleaning quality that is unlikely to be achieved manually

 ● The optimised use of cleaning chemicals and freshwater introduced at temperatures of up to 90 degrees 

● High-pressure driven spray nozzles that can clean and decontaminate in places that would be hard to reach manually
