    Car Wash. OsciJet.

    Robust and fast.


Car wash made easy.

You’re probably familiar with the “wash me” prompts that some little rascals scribble on the rear window of a dirty vehicle with a quick finger. What is so easy with a finger is not so easy in automated cleaning. Car washes are not rocket science, but there is a lot more know-how in them than is commonly believed. Let us give you a brief overview of the background to commercial car washing on this page.

Whether portal or continuous systems, they all have in common that the protection of the vehicle and the paint is paramount. Damage to the vehicle can not only result in recourse payments, but can also quickly paralyze a system. For this reason, most systems first rinse off the coarsest dirt with a prewash and apply a liquid film that prevents dirt particles from acting like sandpaper. Of course, the wheels are particularly stubbornly dirty. Tar, road surface and brake dust form a resistant patina that is usually loosened in a separate step with high pressure and sometimes mechanically. The prewash is then followed by a foam treatment that loosens deeper-lying dirt, which is then removed mechanically with brushes and rags. Since some of the dirt is electrostatic, nothing works here without mechanical assistance. The main wash is followed by a polish treatment that removes very deep-seated dirt from the paint.

After that, everything is rinsed off again in the rinse cycle and, last but not least, a coat of wax is applied to make the paint resistant to new dirt and, in addition, a drying aid is applied to ensure that the paint dries quickly and without stains. In the end, the remaining droplets are blown off and the vehicle is clean again. In addition to the numerous cleaning agents that are matched to each process step, specially adapted nozzles are also used.
After all, to operate a carwash profitably, a high throughput is necessary, and time is a crucial factor here. But choosing the wrong nozzles quickly leads to maintenance work when they become worn or clogged. The conditions placed on the competent people in a plant are tough. In particular, the humid environment, the dirt and the cleaning agents place high demands on robustness.In the following graphic, we show you how a carwash can be optimized by using OsciJet nozzles. For the example we have chosen a continuous flow system, but the nozzles can be used just as well in a gantry system or a self-service wash box. Finally, it remains to be said that cleaning a vehicle involves more than just an aesthetic aspect. A clean vehicle contributes to driving safety, because a clean and shiny paint is more noticeable and clean windows and lights are probably self-explanatory. In addition, paint and underbody care contributes to the value retention and sustainability of a vehicle.

Water consumption

What about the water consumption during the car wash and can you clean your car with a clear conscience even in high summer?

There are various reasons for cleaning your car. One important aspect is road safety. A clean vehicle is more visible and a clear view and clean lights contribute significantly to road safety. Another aspect is the paint and underbody care which contributes to the value retention and sustainability of the vehicle. In addition, car washing binds pollutants, but more on that in a moment.

But what about water consumption? Manual car washing generally consumes up to 140 liters of water per wash cycle. If you use a high-pressure cleaner, you will quickly use considerably more. A modern car wash uses up to 600 liters of water per vehicle, depending on the manufacturer and type. Car washes that work purely with fresh water have become rare but can still be found. Most facilities have a water treatment system that allows the majority of the water used to be reused. Thus per vehicle usually between 25-30 liters of fresh water are needed. In addition, the treatment separates pollutants such as oils and other operating materials separately, so that these cannot get into the groundwater. Thus, a car wash, like a dishwasher, is more economical than hand washing. This means that you can have your vehicle washed in burning heat without having a guilty conscience.

Reduction of operating costs. An example.

We would like to show that sustainable action is not only good for the environment, but can also have a lasting effect on operating costs using two examples.

One of our customers operates a service station with a gantry car wash on a rural road in Lower Saxony. By replacing the original nozzles with OsciJet nozzles, the customer was able to reduce consumption per wash cycle from 243 liters of water to 161 liters. This corresponds to a saving of 34%, which is also reflected in the costs. Based on water costs of 2.71 € per m³ (fresh and waste water), this alone results in a saving of over 460 € for 2000 vehicle washes.

Another customer of ours operates a carwash and has replaced the red nozzles for sill cleaning and rim cleaning with the OsciJet HPX-CW. Due to the use of service water, the customer has normally used up 4 sets of rotor nozzles within half a year, whereas the OsciJet nozzles, which have been in operation for half a year, have not yet shown any signs of wear.


Especially for car cleaning, we have teamed up with customers and adapted our nozzles to the needs of car washing. In addition to the cleaning performance, the robustness and clogging tendency is an essential aspect. Thus, the nozzles are also adapted to the use of industrial water. Unlike flat spray nozzles, the nozzles do not have sharp edges for jet generation and are therefore less prone to wear. Below we show our Dream-Team for car cleaning. This Dream Team helps to significantly shorten cleaning time and save operating costs by reducing water and energy consumption.

OsciJet LPX-DS

Low pressure fluid distribution

Whether rinsing or wax & drying aid (CTH) application, the LPX-DS always cuts a brilliant figure. It is specially designed for uniform distribution and high spray speed, so that even air currents in the plant cannot blow away the spray.

OsciJet HPX-CW

High pressure for car wash

The HPX-CW is specially designed for the car wash sector. This means that the frequency and thus the droplet size have been optimally designed for the surface cleaning of vehicles and are particularly compact. It can additionally be equipped with a nozzle guard.

OsciJet HPX-CS

High pressure cleaning nozzle

The OsciJet HPX-CS operates at up to 200 bar operating pressure and can also handle used water. It is extremely robust and designed for coarse contamination.

The right nozzle. For every System.

As an innovative company, FDX offers you the right nozzle for your plant. From a wide range of standard nozzles, we can determine the right nozzle for you. For special applications, we use state-of-the-art simulation software to tailor the OsciJet nozzle to your application.
