Cleanload Nexus - The Closed Transfer Coupler for easyconnect caps


All of the moving parts of Cleanload Nexus have been tested in extended life cycle tests of up to 100,000 cycles. It has also been proven in practice with more than 100 prototypes tested with chemical on farms during the product development phase.



Make a visual check of Cleanload Nexus before use, lift the top cover and check the umbrella valves and white securing teeth.

Check that mounting is secure and the operating handle moves freely and all hose connections are tight.

Only use containers with factory fitted easyconnect caps and check that suction is drawing from Cleanload Nexus before fitting a container.

Test with a container of water to check for leak-free transfer before using chemicals. 

Are the orange umbrella valves and white teeth in place and clean?

Are hoses connected tightly and leak free?

Is suction open to the tank and drawing from Cleanload Nexus?

Are Containers securely fitted with easyconnect caps?

Is a clean water supply connected?

Is mounting secure and does the handle turn easily?


after use - CLEAN IT!

The simplest thing you can do to ensure long life and trouble free operation for your Cleanload Nexus is to kept it clean! 

After filling the sprayer discharge one final container of water (or suitable cleaning agent) and rinse it though, this removes any trapped residue in the coupler.

Refit the Top Cover to protect from dirt and dust when not in use and run antifreeze through and then drain upside down for 48 hours before storing over winter.

For full details of these procedures, follow the operating manual.
