ESA SERIO TPF Bộ điều khiển đóng mở

ESA SERIO TPF is a microprocessor controlled servomotor that is suitable for controlling air flow regulation valves that are set in predefined positions. The device controls the valve in three fixed positions: minimum, intermediate and maximum opening according to the incoming commands received. Detection and regulation of the three positions can take place via the internal limit switch or via external flow switches. The aluminum casing of the servomotor makes it particularly suitable for industrial applications, allowing the application in the immediate vicinity of the burner.

APPLICATIONS

• Control of air valves for three-stage pulse controlled burners (OFF/MIN/MAX), with air valve capacity control with burner off.
• Control of air valves for double stage impulse controlled burners (OFF/MAX or MIN/MAX).
• Turn-on the burners to minimum power, pulse rate between minimum and maximum burner power, furnace prepurge or controlled cooling only with air.
