Electronically actuated nozzles

Electronically controlled nozzles represent the ultimate level of control for spray systems. 

The HydroPulse® electric spray nozzles from BETE deliver precise intermittent spraying solutions 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. 

There are two models of Electric HydroPulse: the Electric HydroPulse Hygienic (EHP) model for food processing applications and the Electric HydroPulse Industrial (EHPi) mode for industrial spraying applications such as manufacturing engineered wood products. 

EHP and EHPi spray nozzles do not require a compressed air source and are capable of cycling on/off up to 150 cycles per second. These features afford the option of using high-frequency cycling known as Pulse Width Modulation (PWM) to vary the liquid spray flow rate at constant supply pressure with little change in spray performance by adjusting the duty cycle. When the spray cycles at high frequencies, coverage uniformity is maintained because the duration between pulses of spray is short enough to ensure there are no gaps in the spray coverage. These features save valuable spray media while enhancing product quality.

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.

Follow the menu on the right or view the datasheets below for more information about the EHP and EHPi nozzles. To discover more about when you might choose electric nozzles over other types of nozzle, watch our videos below.

Control systems for electric nozzles

The FlexFlow™ system from BETE offers a simple yet highly sophisticated means of controlling up to 20 nozzles in 20 independently controlled spray zones! Read more below.

FlexFlow™ Precision Spray Control System

The FlexFlow system offers a simple to operate but highly advanced interface to regulate the on and off cycles of the nozzles attached to it. The system can be used with the EHP and EHPi nozzles and other automatic spray nozzles such as the Pneumatic HydroPulse (PHP) and XA and SAM air atomising nozzles.

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 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!
