650 Litre (172 gallons) Baffled Car Valeting Water Tank.
Product Overview
The 650 Litre Car Valeting Water Tank is a robust and practical solution for the storage and transportation of potable water and other compatible liquids.
Manufactured from durable MDPE / polyethylene, this flat baffled tank provides a substantial 650 litre nominal capacity, equivalent to approximately 172 gallons. Its low-profile rectangular design makes it particularly well suited to vehicle-based applications where available height is restricted.
The tank has been specifically designed with mobile applications in mind and is ideal for car valeting, window cleaning, mobile pressure washing, vehicle cleaning and other businesses that need to transport a significant volume of water.
An integrated baffle system helps reduce the movement of water inside the tank during transportation. The baffles are formed through grooves and openings within the tank, disrupting the movement of the liquid and helping to reduce side-to-side sloshing.
The tank is manufactured in natural translucent medium-density polyethylene as standard, allowing the approximate water level to be viewed through the tank wall.
The tank is supplied with a 1" BSP outlet and an 8" lid, with a range of optional accessories available to configure the tank for different applications.

Flat, Low-Profile Design
The 650 Litre Car Valeting Water Tank has been designed with a broad, low-profile footprint, making it particularly suitable for vehicle-based installations.
With dimensions of approximately 1010 × 1250 × 575 mm, the tank provides a substantial 650 litre storage capacity without the greater height associated with an upright tank of the same capacity.
This configuration can be particularly useful when installing the tank inside vans, trailers or other mobile cleaning vehicles where available headroom may be limited.
The flat design also provides a relatively broad base, making it well suited to appropriately designed vehicle mounting systems.
Suitable applications include:
- Car valeting
- Mobile car cleaning
- Window cleaning
- Mobile pressure washing
- Vehicle cleaning
- Commercial cleaning
- Potable water transportation
- Mobile water supply
- Agricultural applications
- Horticultural applications
- General-purpose liquid transportation
The available installation area should be checked carefully before ordering, including sufficient clearance for the lid and outlet connections.
Integrated Baffle System
The integrated baffle system is one of the key features of this tank.
The baffles are created through grooves and openings that run through the tank, helping to disrupt the movement of liquid inside the tank.
When a tank containing a large volume of water is transported, the water can naturally move from side to side. This movement, commonly referred to as sloshing, can place additional forces on the tank, mounting system and vehicle.
The internal baffles help reduce this movement by breaking up the flow of water within the tank.
This makes the tank particularly suitable for businesses and professionals who need to transport water as part of their work, including:
- Car valeters
- Mobile valeting businesses
- Window cleaners
- Mobile pressure washers
- Vehicle cleaning companies
- Commercial cleaning businesses
- Mobile water supply operators
The baffling system reduces water movement but does not eliminate it completely. The tank must therefore be correctly installed and securely restrained before transportation.
Please note that the baffle design reduces the usable capacity of the tank compared with an equivalent tank without internal baffles.
Ideal for Car Valeting
The 650 litre capacity makes this tank particularly well suited to professional car valeting and mobile vehicle cleaning.
A large onboard water supply allows operators to carry water directly to the job rather than relying entirely on an external water source at each location.
This can be particularly useful for:
- Mobile car valeting
- Fleet cleaning
- Commercial vehicle cleaning
- Dealership valeting
- Vehicle detailing
- Mobile pressure washing
- On-site cleaning services
The baffled construction is especially useful for mobile applications because it helps reduce the movement of water while the vehicle is travelling.
Applications
The 650 Litre Car Valeting Water Tank is suitable for a wide range of professional and commercial applications.
Typical uses include:
- Car valeting
- Mobile car cleaning
- Vehicle detailing
- Window cleaning
- Mobile pressure washing
- Commercial vehicle cleaning
- Fleet cleaning
- Dealership valeting
- Commercial cleaning
- Potable water transportation
- Mobile water supply
- Agricultural applications
- Horticultural applications
- General-purpose liquid transportation
Its combination of high capacity, flat construction and internal baffling makes it particularly suitable for mobile applications where water needs to be transported safely and efficiently.
