A new electrically actuated, automatic SPRAY NOZZLE for precision food processing and industrial applications is the latest product from BETE available in the UK through THE SPRAY NOZZLE PEOPLE. Eliminating (or at least minimising) waste and reducing over-spray are important objectives in most processing / manufacturing environments and this is where the HydroPulse® Spray Nozzle will be appreciated.

HydroPulse nozzles ensure that precise volumes of ingredients and compounds can be sprayed directly onto a processing target, with overspray waste virtually eliminated. When combined with BETE’s FlexFlow™ Precision Spray Control System uniform and consistent coverage can be achieved, even when conveyor speeds need to be adjusted.

The nozzles do not require a compressed air source and are capable of cycling on/off up to 150 cycles per second. This enables the option of using high-frequency cycling known as Pulse Width Modulation (PWM) to vary the liquid spray flow rate at a 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 is short enough to ensure there are no gaps in spray coverage.

HydroPulse stainless steel electric spray nozzles are available in two main options. These are a hygienic food grade design with 1/8”, NPT, BSPT and ½” tri-clamp connections and provide a maximum liquid flow rate of 3.8 litres / min, maximum pressure of 17 Bar and a maximum cycle frequency up to 150 cycles / sec. An industrial design option provides a maximum flow rate of 3.8 litres / min, maximum rated pressure of 20 Bar and a maximum cycle frequency of 50 cycles / sec.

HydroPulse electric spray nozzles are just one of BETE’s performance spray engineering range of products which includes fog and misting nozzles, tank washing nozzles, material injection nozzles, custom spray lances and spraying systems for industrial coating, moistening and lubricating applications.
