Hedson FAQ

The GP24 wheel washer is an automated system for efficient professional wheel cleaning.

Wheels are loaded onto trolleys and automatically fed into the machine, where they are securely positioned and rotated during the washing cycle.

The cleaning process combines water jets with mechanical action and plastic media (plastic beads), which remove stubborn brake dust, road grime, and other contaminants from all surfaces of the wheel.

The trolley system used for Drester GP24 Le Mans wheel washer is an automated loading and transport solution that allows wheels to be easily placed into the machine and securely positioned during the washing cycle.

This system reduces manual lifting, making the workshop environment more ergonomic. It also improves efficiency. Multiple trolleys can be prepared and queued one after another, allowing operators to load new sets of wheels while another batch is being cleaned.

The Drester GP24 Le Mans wheel washer is best suited for workshops and businesses with regular wheel cleaning needs, such as automotive repair shops, tire service shops, car dealerships, and fleet maintenance operations.

It is designed for professional use. Perfect for companies where efficiency, environmental compliance, and consistent cleaning results are important.

The standard cleaning cycles vary from 30-60 sec, with possibilities to use prolonged cleaning programs for very dirty and complex rims.

Yes. The compressed air is used to support key machine functions, such as wheel handling and parts of the automated washing cycle.

Yes. The Drester GP24 Le Mans wheel washer washes alloy and SUV wheels with a max diameter of 800mm, using the dynamic flush pipe technology.

Wheels with rim surfaces protruding more than 13 mm (1/2”) beyond the tyre sidewall should not be washed in the GP24, as the protruding parts of the rim may be damaged during the washing process.

This mainly applies to certain custommade wheels, deep concave rims and some special alloy wheel designs.

No. A flat tire cannot be cleaned in the machine as it will not rotate properly.

Yes. The washing process itself is compatible with TPMS-equipped wheels. Make sure to handle the wheels properly to avoid mechanical damage to the sensors.

Yes. The wash programs in the Drester GP24 Le Mans wheel washer are editable – meaning that you can adjust – times of wash, Clean Rinse and air blow time.

The Clean Rinse function is designed to give the wheel a final rinse with clean water after the main washing cycle. It consumes around 0,3 litres per wheel.

The water in the Drester GP24 Le Mans wheel washer should be changed every 300 wash cycles. If the Clean Rinse function is being used in the machine, the water change intervals may be increased to approximately 400-500 washes.

The Drester GP24 Le Mans wheel washer can be equipped with an optional water treatment and filtration system that enables water recycling. The system separates dirt and contaminants from the wastewater.

It’s not recommended to recycle the cleaned water as the ph value will eventually be affected.

The wastewater from Drester GP24 Le Mans wheel washer contains dirt from roads and vehicles, which may include heavy metal residuals.

Wastewater should normally be discharged through an oil separator.

If needed, the machine can be fitted with Hedson’s environmentally friendly water cleaning and filtering system that separates contaminants from the water, allowing the treated water to be safely discharged into the drain. This can be made manually in the machine or automatically by using the Drester Filter eQ.

When using the Hedson water cleaning system, the wastewater meets applicable water authority requirements. Local regulations may vary, so users should consult their local water authority for specific discharge limits.

It optimizes energy usage by automatically managing heating based on the workshop’s operating schedule.

Users can set the time when the machine should be ready for operation in the morning, when it is no longer in use in the afternoon, and which weekdays the schedule applies to. The system then automatically starts heating the water in advance so that it reaches the desired operating temperature at the selected start time.

This intelligent heating function can save up to 50 percent more energy compared to a traditional thermostat-controlled heater.

By default, the machine is set to operate from 07:00 to 16:00, Monday to Friday, ensuring the water is maintained at operating temperature during working hours.

If continuous heating is preferred, the schedule can be set from 00:00 to 00:00, Monday to Sunday, which keeps the water heated 24/7.

This wheel washer is designed with energy efficiency in mind. It features an intelligent water heating system that can reduce energy consumption by up to 50 percent compared to traditional thermostat-controlled heaters.

The machine also supports programmable scheduling. This helps minimize unnecessary energy use while ensuring the machine is ready when needed.

The Drester GP24 Le Mans wheel washer is equipped with an advanced current monitoring system that measures the pump motor’s energy consumption during operation.

The machine displays the average energy consumption per wash cycle, giving workshops better insight into operational efficiency and machine performance.

The statistics are automatically reset each time the machine is cleaned.

The DoublePower granulate (shot medium) mixture of plastic beads that are used to clean the wheels in the Drester GP24 Le Mans wheel washer can be ordered using the number 230794 (bag containing 20 kg).

When changing the water after appr. 3-500 washed wheels, the granulate is gathered in a metal basket. If necessary, some additional granulate is added.

In an empty Wheel washer 20 kg of Drester Doublepower granulate (Shot medium) is needed.

The Drester Dynamic Triple is a closed solvent recycling system developed for automotive body and paint shops. It combines a Drester solvent recycler, an RDX docking unit and a Drester solvent spray gun cleaner into one integrated system that minimizes solvent handling, reduces waste and lowers operating costs.

A closed solvent handling system transfers contaminated and recycled solvent between equipment without operators pouring or carrying solvent manually. This reduces exposure to solvent fumes, minimizes spills and improves workshop safety.

Dynamic Triple is designed for professional automotive body shops, collision repair centres, commercial vehicle paint facilities and industrial paint operations that use solvent-based spray guns.

Used cleaning solvent from the spray gun cleaner is transferred to the Drester 120 solvent recycler. During recycling, clean solvent is distilled from paint residues and returned for reuse. Approximately 95% of the solvent can be recovered.

The Drester 120 solvent recycler can recover approximately 95% of the used solvent, significantly reducing purchases of new solvent.

Recycling solvent helps:

• Reduce solvent purchases
• Lower hazardous waste disposal costs
• Reduce environmental impact
• Improve workshop sustainability
• Improve profitability

Yes. Recycling dramatically reduces hazardous waste while minimizing the amount of new solvent required for daily operations.

Every litre of solvent that is recycled avoids both the purchase of new solvent and the disposal cost of contaminated solvent.

Using the example provided in the white paper, a typical body shop can achieve payback in approximately 32 months for the complete Dynamic Triple system, depending on solvent usage and local disposal costs.

Disposal of contaminated paint solvent typically costs more than purchasing fresh solvent because hazardous waste requires approved handling and processing.

Yes. The system is designed to connect to Drester solvent and Combo spray gun cleaners, making upgrades straightforward for existing users.

Yes. Cleaner solvent reduces contamination inside the spray gun cleaner, helping extend its service life.

The system minimizes manual solvent handling, reducing exposure to harmful solvent vapours, heavy lifting and accidental spills.

Yes. Because solvent remains inside a closed system throughout recycling and transfer, staff have significantly less exposure to solvent vapours.

Manual handling increases the risk of:

• Chemical exposure
• Spills
• Fire hazards
• Worker injuries
• Environmental contamination

A closed system helps reduce all of these risks.

The Drester RDX docking unit allows solvent transfer over distances of up to 25 metres, giving workshops greater flexibility when planning layouts.

Yes. Subject to local fire regulations, the recycler may be installed separately from the spray gun cleaner, improving safety and workshop layout flexibility.

Routine maintenance consists mainly of:

• General cleaning
• Condenser coil inspection
• Occasional lid gasket replacement

With proper maintenance, systems can remain operational for more than ten years.

Typical service life is 7–10 years, although many systems remain in operation well beyond this with proper maintenance.

By recovering usable solvent rather than disposing of it after a single cleaning cycle, hazardous solvent waste is significantly reduced.

Solvent recycling supports sustainability by:

• Reducing chemical waste
• Conserving raw materials
• Lowering transport associated with solvent deliveries and waste disposal
• Reducing overall environmental impact
