Spray Washers

Our range of spray washers are used by multiple industries to remove grease, oils, dirt, paints, inks and any other type of contaminant. We can design all our spray washers to use either an aqueous detergents or ATEX certified solvents depending on the contaminants being removed.

Our spray washers are an efficient way of stripping any component of unwanted surface contaminants. To make sure we have the perfect solution for all our customers varying need we supply two full product ranges, each with multiple sizes available.

What do our clients think?

“From the outset, the experience was one where we were kept informed of each stage of the project and it was ultimately delivered precisely when we wanted. I will have no hesitation in dealing with the team again and hope to do so in the near future.

I would highly recommend them for the quality of product and professionalism throughout the entire process. Top job!”

Degreasing Machines from Rotajet

Rotajet Systems are one of the UK’s most respected experts in the design and manufacture of degreasing equipment. We offer a complete range of degreasing machines including parts washers, ultrasonic machines as well as a full selection of ATEX certified washers.

We provide a full turn-key solution to your cleaning needs, handling every aspect of your process. Our team handles everything from design right up to machine maintenance and servicing so you can concentrate on what you do best!

In our manufacturing base in West Yorkshire, we have built our reputation on combining chemical and mechanical engineering to create cleaning solutions that keep our customer’s workers safe, their productivity high, and their waste low.

Depending on the size and weight of your component, our spray washers can be loaded in different ways to reduce manual handling. Our small top-loading spray washers such as the RJ-TL650 are designed for small components can be loaded manually directly into the wash chamber. External loading is included in our larger machines allowing the operator to load larger parts, such as engines. These machines can be loaded manually or in conjunction with standard lifting equipment such as an overhead crane.

Each of our machines is designed to support an automatic cycle, freeing your operators to complete other tasks. The temperature, cycle time, and flow rate are variable allowing you to fine-tune your process to maximize efficiency.

The exact process that your machine will undertake will vary depending on your requirements and this will be covered in full during the design process. Our machines can be offered as a single-stage, two-stage, or in the case of the food industry a three-stage wash.

Once the cycle has been completed, the steam is extracted, interlocks are disengaged and the component can safely be removed.

With nearly 1000 machines worldwide across a huge variety of industries, we have extensive experience in the selection, supply, and dosing of washing chemicals. We use this knowledge to inform all our projects and offer whatever level of support you need.

If you have a specific cleaning chemical in mind, we can manufacture our machines to suit your current procedures or our team can advise and/or supply you on the best chemicals to use.

We have been manufacturing spray washers for over 30 years. In this time, we have worked with many industries, each with their own unique issues and contamination. Therefore, our standard washers can be adapted to handle many types of contamination.

Manual cleaning of this equipment would not only be unrealistic in terms of keeping production on track but also extremely uneconomic due to the amounts of water and cleaning detergent that would be required; not to mention the costs of labour.

For food production companies producing high quantities of goods; a spray washing machine can make for a quick return on investment and be the more financially viable option for washing. On top of this, the food industry can be subject to more complexities than other industries when it comes to health and safety. 

Washing methods used must be sufficient for removing any potentially hazardous contaminants: a risk that can be considerably reduced through the use of an automated washing machine

Examples of contamination


Vegetable Oil, Fuels, Grape Seed Oil, Sesame Oil, Avocado Oil

Food Stuffs

Milk, Honey, Liquid Yeast, Essences, and flavours


In our range we have spray washers that have been specifically designed to wash solvent based paints and inks. It is our duty to ensure that the machine has been designed according to ATEX standards to protect against the possibility of ignition.

An ATEX spray washer is typically fully pneumatically driven, removing the possibility of electrical spark. If you are looking to wash containers contaminated with solvent based inks or paints, why not have a look at our specially designed container washers.

No matter the nature of your cleaning application, Rotajet Systems have the knowledge and experience to ensure that your system will suit your needs. Allowing you to reallocate labour to where it is needed whilst creating a reliable and repeatable cleaning quality.

The remanufacturing process can be broken down into the following 6 key stages:

The product, or ‘core’, is broken down into its’ constituent components.
Each individual part is cleaned; either manually or using a machine such as a spray washer. Much of the cost involved with remanufacturing can be attributed to the manual option of this stage as it can be both a laborious and time consuming task; not to mention resources such
as water and the risks involved with cleaning hazardous parts by hand.
There is no standard measuring stick by which to assess the cleaning quality of parts. Much of this comes down to visual inspection. This can be another costly stage as cleaning efforts may vary between manufacturers; incurring an extra cost for the lower standard of clean
This is another stage which can be made more efficient through the use of a part-washing machine, such as the previously
mentioned parts cleaning and degreasing spray washer.
Parts which do not achieve the expected standard are then either scrapped or sent through the alternative process of component remanufacture. Parts which are scrapped or
cannot be remanufactured are then replaced with new or remanufactured parts.
Using the cleaned and/or replaced components, the ‘core’ is then put back together according to the original equipment manufacturers specification (OEM).
Using the cleaned and/or replaced components, the ‘core’ is then put back togetheaccording to the original equipment manufacturers specification (OEM).

To complete the manufacturing process, the machine must then be tested to ensure it satisfies all of the necessary criteria, much like in the original manufacturing stages of the new product. It is important for this stage to run smoothly in order to place the item on the market for resale, as not doing so can become another costly process.

It is the highly laborious and time consuming nature of the stages mentioned above that can contribute to the high costs of remanufacturing. In particular, it has been found that the cleaning stage, assuming up to 20% of the overall costs alone, is accountable for the largest cost of all; especially in automotive remanufacturing. 

Not only can this be attributed to the costs of labour, but the resources used in line with this process: manually cleaning can mean the use of more water, chemicals and energy that could otherwise be streamlined and optimised through an automatic cleaning machine. These findings have also been reflected in research, which shows that, among other factors, such as; cleaning standards and requirements within the relative sector, environmental regulations, etc, the more complex the washing process is within a company; the higher the incurred costs are for this stage.

Although it can be a time consuming task, remanufacturing has actually been found to have a great deal of advantages when compared to manufacturing new products. For example; remanufactured items can take up to 80% less energy to produce and can additionally save up to 80% in cost due to the cheaper nature of the used materials. Aside from being financially sound, remanufacturing can also have a comparably more positive impact on the environment; in some cases producing up to 90% less greenhouse gases than original manufacturing.

Overall, while there can be constraints and complications involved with remanufacturing parts; the operation can evidently turn a considerable profit. On top of this, costs can be controlled and optimised through the adoption of efficient processes, such as the use of cleaning machines,
which can make for a financially sound business model.
