Under Chassis Wash Jet

Under Chassis Wash Equipment is the safest environment in which to clean the underneath of HGVs and PSVs.
An Under Chassis Wash is an automatic, programmable, cost-effective and efficient method of safely removing corrosive salts, oils and dirt.

Under Chassis Wash Features:
- The totally safe environment when compared with manual cleaning.
- Up to 75% shorter time than cleaning manually.
- Cost savings to the company are easily measured.
- Vehicle technicians have a cleaner working environment.
- Throughput of vehicles greatly increased, maintenance efficiency improved due to earlier fault detection.
- Chassis cleaning cost is forecastable.

Equipment Operation.
- For the operator, Under Chassis Wash Equipment is simple in use.
- The driver aligns the vehicle over the wash pad, then selects on the programme controller the number of the programme required and presses the start button. The whole operation is fully automatic, the under chassis trolley moves along the track spraying the underside of the vehicle using its unique nozzle.
- The programmer can store up to 40 programmes allowing for variations in the vehicle length and time required for the wash.
- These variables can be programmed at the time of commissioning the equipment if needed. Programmes can be easily changed or added, no additional equipment is needed to do this.
Improved Efficiency.

- The operation efficiency when compared to a manual cleaning system is cost effective. Not only the throughput of vehicles in an hour, but also from a vehicle technician's aspect, meaning lower maintenance costs.
- As the programmes are fixed, the costs for fuel, water, detergent and electricity can easily be costed and a budget prepared.
- After installation, it has been found that service times and breakdowns have been reduced.
Simple Installation
- Installation can be to a constructed ramp or over an existing pit, the trolley rails are bolted to the floor.
- Variables such as detergent injection, pre wash foam, water, pressure reduction, protection against freezing and a manual lance can all be installed as per the client's on site requirements.

- It has a zinc plated or a galvanised fabrication, housed under a fixed fibre glass lightweight cover.
By-laws Compliance, Water Boost Set.
A 227 litre plastic tank incorporates the required air gap between the stored water level and the town water supply, the water inlet float valves and the overflow in accordance with the water by-laws compliance boost set.
To feed the high pressure triplex Cat pump, there is a centrifugal boost pump that is connected to the storage tank, this ensures optimum flow and pressure both for the maximum reliability and performance.
A float valve controls the water level in the storage tank, the storage tank houses a low level float switch when, if the water level falls isolates all supply to the pumps to prevent damage. The storage tank and all pipe work associated with it is protected against frost.
Application of the detergent.
The Under Chassis Wash Equipment offers two different applications, either a foam application used to soak prior to a high pressure wash or, a detergent injection that is carried out during the wash.
Remote Cable Winding Drum.
Where the Under Chassis Wash Equipment is mounted over a pit, or where it is impractical to locate the pump and drive units in the same area.
Hot Water Module
The 3 pass heat exchanger provides either 45 or 90 ltrs/min at 70°C and is either oil or gas fired, this unit fits within the housing in a lightweight fibre glass cover. The heat exchanger is fitted with either Selectors or Nu-Way burners.
Note. The customer must supply and install all exhaust gas flue ducting.
Automatic Frost Protection.
The frost protection system prevents use of the equipment until the frost stat has been reset, this prevents damage to the pump(s). The frost stat can be set to a pre-determined setting, if the stat cuts in, an electric valve is opened that clears the high pressure hoses of water using compressed air, preventing them from freezing.
Hand Lance System
For occasional manual cleaning, the hand lance is used, high pressure water from the pump is diverted for its use.
