SPRAYEYE® Dual integrates a conventional visual video stream with GEA IR camera technology (patented). The conventional view is used by operators to monitor spray dispersal, identify nozzle leaks and detect product build-up on the spray nozzles; the infrared (IR) camera provides a thermal image of the nozzles’ temperature and continuously monitors the temperature and heat variation on each spray nozzle to automatically detect and highlight product build-ups that begin to smolder.
By combining these two complementary technologies, the SPRAYEYE® Dual early warning system helps to prevent fires and explosions in the dryer by detecting hazardous temperature increases and hot spots before they become a problem.
Most fires result from unnoticed temperature changes in the drying chamber. SPRAYEYE® Dual identifies and draws attention to high temperatures in the following ways:
- any nozzle with a high temperature is highlighted visually on the thermal display
- an alarm is triggered when a temperature exceeds the predefined limit
- the alarm may be sent to the Scada system and shown on the operator screens
- the system will log the event and start recording temperature data and images
SPRAYEYE® Dual temperature scanning technology (patented) delivers the following benefits:
- improved nozzle monitoring when operating at higher temperatures
- high reliability and minimum maintenance
- automatic monitoring to free up operator time
- prewarning system to highlight problems before they can be visually observed
- adequate time for operators to solve problems before they escalate
- accurate, reliable surveillance for better safety and control
Dual technology for safer operation
The SPRAYEYE® Dual provides both visual and thermal surveillance in one device. The system raises a prewarning alarm before abnormal carbon monoxide levels can be detected; it indicates the exact position, temperature and size of the problem to help operators react effectively.
The integrated management of alarm levels, definition of areas for automatic monitoring, camera protection systems and simple calibration helps to ensure a higher level of risk management.
The SPRAYEYE® Dual enables operation with increased inlet air temperature at less risk, and some customers have been able to retain their standard operating conditions when moving to a more flammable recipe.
