Rapid Spray recommends considering:

• Liquid compatibility (weight/SG)

• Capacity requirements

• Application needs (portability, durability, spray features)

• Transport and mounting requirements (e.g., galvanised steel frames, trailer compatibility)

To reduce slosh and surge, Rapid Spray offers a Ball Baffle System, especially effective for tanks over 800 L (large baffles) and up to 600 L (small baffles). These help stabilise the liquid during transport.

Find out how Ball Baffles can help reduce the slosh and surge in vehicles, and improve liquid transport.

Yes – some of them include:

• Always follow vehicle manufacturer guidelines, including payload limits.

• One litre of water weighs one kilogram; overloading can be dangerous.

• Tanks are not certified for transporting dangerous goods unless expressly advised.

• Ensure safe mounting, full base support, and correct use of fittings. Improper use may void warranty and pose safety risks.

Always follow the safe operating procedures of your vehicle and as outlined in the operators handbook. Always follow local, state and federal regulations.

Rapid Spray offers FlexConnex Modular Tanks in V1 and V2 versions:

• Expandable “plus-one” system that allows adding more modules as needs grow.

• Two-way baffle system provides both longitudinal and lateral liquid stabilization.

• Compartmentalisation, enabling separate or combined draining/filling.

Yes – all the Rapid Spray manufactured tanks, such as the Portable Water Cartage Tanks (Aqua-V) are food-grade and UV-stabilised for potable water transport, with the full 25-year* warranty included.

Most tanks are offered via dealer pickup; you choose a local distributor who handles shipping and collection. Supporting local dealers also ensures better after-sales service.

While water cartage tanks are suitable for water, transporting liquid fertiliser requires tanks specifically designed for such chemicals. These specialised tanks are constructed with materials resistant to the corrosive nature of fertilisers, ensuring longevity and safety.

Our Active range and above is especially made for the transport of liquids such as fertilisers.

To minimise liquid movement, consider tanks equipped with internal baffle systems. These systems reduce wave motion, enhancing stability during transit.

The Ball Baffle range has been designed specifically to reduce the slosh and surge of liquid inside tanks.
