## LEISUWASH DG HP Touchless Automatic Car Wash System

### Technical Description and Specification

The **LEISUWASH DG HP** is an automatic in-bay rollover car wash system designed for touchless exterior vehicle cleaning. During operation, the vehicle remains stationary while the gantry travels along floor-mounted rails and performs the selected washing programme.

The machine uses automatic vehicle detection and contour-following technology to position the chemical applicators, high-pressure water jets and drying system at controlled distances from the vehicle. The main bodywork is cleaned without rotating brushes, reducing the risk of mechanical contact with painted surfaces.

## Washing technology

### Contour-following chemical application

The DG HP is fitted with a multi-stage chemical system capable of applying different cleaning products during separate stages of the wash programme. The application assembly follows the detected vehicle contour to provide more even chemical coverage.

Depending on the selected configuration and programme, the system can apply:

* pre-wash chemicals;
* shampoo or active foam;
* lava foam;
* wheel-cleaning chemicals;
* wax or surface-protection products;
* spot-free reverse-osmosis rinse water.

The purpose of the chemical pre-treatment is to soften and release dirt before the high-pressure washing stage begins. ([Leisuwash][2])

### Contour-following high-pressure washing

After chemical application, the system cleans the vehicle using high-pressure water jets. LEISUWASH specifies a normal operating distance of approximately **350 mm** between the washing assembly and the vehicle surface, with washing pressure of up to **100 bar** in the standard manufacturer description.

Automatic contour detection allows the washing assembly to follow the front, roof and rear profile of different vehicle types. Additional lateral high-pressure jets clean the sides of the vehicle.

Because the principal body-washing process uses chemicals and pressurised water rather than brushes, there is no rotating-brush contact with the vehicle’s main painted surfaces. ([Leisuwash][2])

### Wheel-cleaning system

The DG HP can be equipped with bi-directional rotating wheel brushes. During the wheel-cleaning stage, chemical is applied to the tyre and wheel area, after which the wheel brushes rotate in both directions while high-pressure water assists in removing brake dust and road contamination.

The wheel brushes are separate from the main touchless body-washing system and are intended specifically for the wheels and tyres. ([Leisuwash][2])

### Contour-following air dryer

The machine incorporates a flow-optimised air-drying system that follows the contour of the vehicle. The manufacturer specifies an approximate drying distance of **250 mm** and a standard dryer power rating of **16 kW**.

The controlled distance between the dryer and the vehicle is intended to concentrate airflow on the body surface and reduce unnecessary airflow losses.

An optional variable-frequency silent drying system is also available. According to LEISUWASH, this option can reduce drying-system noise and energy consumption by approximately **35%**, depending on operating conditions and configuration. ([Leisuwash][2])

## Standard and optional functions

The manufacturer lists the following principal DG HP features:

| Function | Availability |
| ---------------------------------------- | ---------------------------------- |
| Contour-following high-pressure rinse | Standard |
| Contour-following chemical application | Standard |
| Contour-following air drying | Standard |
| Side air drying | Included in the drying arrangement |
| Bi-directional wheel scrubbing | Available as part of the DG system |
| High-pressure oscillating side rinse | Optional |
| Variable-frequency silent air dryer | Optional |
| Lava-foam application | Configuration-dependent |
| Wax application | Configuration-dependent |
| Spot-free RO-water rinse | Configuration-dependent |
| Online or unattended payment integration | Configuration-dependent |

([Leisuwash][2])

## Automatic operation

A typical automatic wash cycle can include the following stages:

1. Vehicle positioning and detection
2. Chemical pre-wash application
3. Shampoo or foam application
4. Wheel and tyre cleaning
5. Contour-following high-pressure washing
6. Side high-pressure rinsing
7. Wax or protective-product application
8. Spot-free final rinse
9. Contour-following air drying

The exact sequence is programmable and depends on the wash package, installed options and chemical arrangement.

The system can be integrated with a payment terminal, voice-guidance equipment or another local payment solution for unattended operation. LEISUWASH presents the DG as suitable for 24-hour self-service installations when connected to an appropriate payment and access-control system. ([Leisuwash][2])

## Main system components

A complete LEISUWASH DG HP installation generally consists of:

* a rail-mounted moving gantry;
* high-pressure washing assemblies;
* chemical application and dosing equipment;
* vehicle-position and contour-detection sensors;
* wheel-cleaning assemblies;
* air-drying units;
* a water-pumping and distribution system;
* an electrical control cabinet;
* a programmable operating interface;
* safety and emergency-stop devices;
* optional payment and voice-guidance equipment.

## Intended use

The LEISUWASH DG HP is intended for automatic exterior washing of passenger cars, SUVs, crossovers and other light vehicles that comply with the permitted dimensions of the specific installation.

It is suitable for commercial car-wash sites, filling stations, vehicle-service centres, dealerships, fleet facilities and unattended wash bays.

## Specification limitation

LEISUWASH offers different DG configurations and optional equipment packages. The manufacturer’s public product page does not provide one universal value for every installation parameter.

The following information must therefore be confirmed from the individual machine’s nameplate, quotation or technical documentation:

* maximum vehicle length, width and height;
* electrical supply voltage and frequency;
* total connected electrical load;
* high-pressure pump power;
* water consumption per cycle;
* chemical consumption;
* compressed-air requirements;
* rail and wash-bay dimensions;
* minimum installation clearances;
* cycle duration;
* water-treatment requirements;
* exact dryer and wheel-wash configuration.
