FLEXFLOW HYGIENIC PRECISION SPRAY CONTROL SYSTEMS FOR FOOD-GRADE APPLICATIONS

BETE’s FlexFlow Spray Systems, designed with a hygienic enclosure, ensure precision control and flexible automation for our Hygienic Electric HydroPulse® and other automatic spray nozzles. These plug-and-play controllers are an elegant solution for precision coating, moistening, and lubricating applications where intermittent spraying will improve accuracy and reduce waste.

Consider the FlexFlow for any food process where expensive compounds or ingredients need to be sprayed directly onto the process target. Each control panel can be used as a standalone system –or upgraded to the 2000 model to integrate with your existing plant operations.

ADDITIONAL FEATURES AND UPGRADES

The BETE FlexFlow spray controllers are standalone electrical control panels that provide user-friendly control of BETE Electric HydroPulse (EHP) series electric-actuated spray nozzles. Hygienic enclosure wall-mounts are an available upgrade add-on. A Siemens brand Programmable Logic Controller (PLC) and associated hardware operate the nozzles. Spray zones can be triggered manually, or they can be triggered automatically using digital inputs from process sensors. User-adjustable signal delays provide the most accurate spray timing functionality.
Electronic Spray Control Pulse Width Modulation (PWM)
The spray flow rate can also be electronically controlled by pulsing the sprays while adjusting the cycle's ON versus OFF dwell time ratio. Pulsing at high frequency allows the average flow rate to be adjusted while maintaining constant fluid supply pressure and the appearance of continuous, uniform coverage. This flow control process is known as Pulse Width Modulation (PWM).

HUMAN-MACHINE INTERFACE

A touchscreen Human Machine Interface (HMI) allows users to configure the spray system and adjust spray parameters through an easy-to-navigate menu of options. Adjustable parameters for each spray zone include nozzle cycle rate, duty cycle, trigger signal delays, and trigger state.

A cable gland plate comes standard with every FlexFlow control panel. Only pierce as many openings as needed through the membrane for easy access to field wiring.
