HydroPulse® Food-Grade Electrically Actuated Automatic Precision Spray Nozzles

BETE’s electric-actuated Hygienic HydroPulse Spray Nozzles (EHP) assure precision volumes of expensive ingredients are sprayed directly onto your food processing target, with overspray waste virtually eliminated. Pair with the BETE FlexFlow™ Precision Spray Control System to achieve uniform coverage, even if you adjust your conveyor speed. For precision coating, moistening, and lubricating applications that do not require a hygienically designed spray nozzle, consider the Industrial Electric HydroPulse alternative.

Food Processing Benefits

  • Control a wide range of flow rates
  • Uniform and repeatable coverage improves product consistency
  • Reduce consumption of expensive coatings
  • Reduce overspray waste and improve product quality                         
  • Exact target coatings secure a clean and safe environment
  • Promote increased production
  • Reduce maintenance and downtime
  • Reliable spray dosing provides an accurate calorie count


Electric HydroPulse 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 a high enough frequency, coverage uniformity is maintained because the duration between pulses of spray is short enough to ensure there are no gaps in the spray coverage.

*Due to pressure loss through the Electric HydroPulse body, the nozzle tip flow rate is different than the standard for each tip. For the CW tips, full cone/hollow cone patterns are suitable for continuous operation only. Not recommended for use with PWM control. Please reference the HydroPulse Electric Metric Datasheet for a resolved flow rate range.
