FlexFlow™ precision spray control

FlexFlow™ precision spray control systems offer a simple to operate but highly advanced interface to regulate the on and off cycles of the nozzles attached to it. FlexFlow can be used with automatic spray nozzles such as electric nozzles and some air actuated nozzles. See below for details about compatible nozzles.

With FlexFlow, you can activate spray zones using automatic triggers such as photoelectric and proximity sensors or make adjustments manually. Additional trigger delay settings provide flexible parameters to reduce material consumption and minimise cleaning maintenance by fine tuning the timing of the intermittent spray onto moving targets.

FlexFlow is ideal for precision coating, lubricating, and moistening applications in food processing, building materials manufacturing and any other industry looking to save resources and improve product quality.

The unique selling point of the FlexFlow system is that it is far easier to install, program and adjust than other compatible systems. We have found that competitor systems are too complex to operate and require specialist knowledge to troubleshoot problems. The FlexFlow is designed to be adjustable in the field by any competent maintenance engineer. You don’t need to be a specialist in spray technology to set up and adjust the system.

What this means is that the hassle is taken out of setting up and adjusting even complex spray setups. There is no need to call us in to make adjustments every time you need to because it is actually pretty straightforward to do this, by design!


There are two models of FlexFlow.

The FlexFlow™ 1000 can programme two zones of unique precision spray control with up to six nozzles in each zone – or synchronise up to twelve nozzles.

The FlexFlow™ 2000 manages up to twenty spray nozzles in up to twenty independently controlled spray zones. It is possible to auto adjust duty cycles to match conveyor speeds in each zone. It includes an Ethernet port for process integration with existing plant operations.

Automatic spray nozzles for precision spraying with FlexFlow™

The following automatic nozzles can be used with the FlexFlow™ system.

HydroPulse® nozzle series

- Electric HydroPulse Food-Grade Hygienic Design (EHP)
- Electric HydroPulse Industrial Design (EHPi)
- Pneumatic HydroDesign (PHP)

EHP & EHPi nozzles
The EHP and EHPi nozzles both work in the same way. Within the nozzle body is a highly sensitive and responsive solenoid shut-off valve. This allows the nozzles to be rapidly cycled on and off up to 150 times per second. The EHP and EHPi nozzle bodies can be fitted with a wide variety of different spray tips. These can form flat fan or full cone spray pattern types. They come in a variety of different spray angles, flow rates, and materials. This gives a huge variety of different spray types.

The PHP is a pneumatically actuated flat fan spray nozzle which improves product quality with uniform, repeatable coverage and drip-free performance. It can be fitted with a wide variety of different spray tips, with a variety of spray angles and flow rates. The addition of a spring loaded shut-off system allows the nozzle to be cycled on and off rapidly.

Air atomising nozzles

- XA

XA 10 & 11 low flow air atomising nozzles
The XA nozzle system has many interchangeable components that can be assembled to achieve a variety of air atomising spraying objectives with a choice of internal or external mix set-ups. For more information on the XA nozzle series components and options, click here.

Separate atomising and fan air lines provide variable coverage and fine control of drop size without affecting liquid flow rates. Higher atomising air pressure yields finer drop size; higher fan air pressure yields broader patterns.

See the nozzle datasheets below and watch our explainer videos to learn more about the different types of nozzles that can be used with FlexFlow™.
