HydroPulse® Automatic Spray Nozzles

BETE’s electric actuated HydroPulse Spray Nozzles assure precision volumes of expensive ingredients and compounds are sprayed directly onto your processing target, with overspray waste virtually eliminated. Pair with the
BETE FlexFlow™ Precision Spray Control System to achieve uniform coverage, even when adjusting your conveyor speed.
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 cycle is at a high enough freque ncy, 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.
Please reference the HydroPulse Electric Datasheet or HydroPulse Electric Metric Datasheet for a resolved flow rate range.
Pneumatic HydroPulse spray nozzles provide a controlled intermittent liquid spray using only liquid pressure as the force for atomization.
It offers a drip-free performance and is pneumatically actuated for crisp on/off precision spray performance.

Air Atomizing
Air atomizing nozzles use the energy in compressed air or gas to produce finely atomized liquid sprays at relatively low operating pressures.
- If you have low pressure and a smaller drop size is needed that cannot be achieved with a single fluid nozzle, an air atomizing nozzle is the perfect choice.
- When a viscous fluid needs to be sprayed/atomized that cannot be sprayed with a single fluid nozzle, an air atomizing design is the best option.
The XA nozzle system has many interchangeable components that can be assembled to achieve a variety of air atomizing spraying objectives, with a choice of internal or external mix set-ups.

Design Features of the SAM flat fan and narrow round automatic nozzle:
- Separate atomizing and fan air lines provide variable coverage and fine control of drop size without affecting liquid flow rates. Higher atomizing air pressure yields finer drop size; higher fan air pressure yields broader patterns.
- Removable plug provided for liquid recirculation port
- External mix; allows spraying of viscous materials
- Liquid flow rates are independent of air
- Precise metering of the liquid flow rate
- Pneumatically-controlled shut-off and clean-out built in
