RAPPERCON™ 900 CONTROLLER

Rappercon™ 900 Controller

Our AVC Specialist brand Rappercon™ 900 Controller is designed to clear fly ash and other particules from the high voltage frames and electrodes of an Electro-Static Precipitator, knock the ash from collecting plates, clear the material inside the hoppers, or move any material in conveyors where plugging is a concern.

The Rappercon™ 900 Controller card rack can handle up to 32 discrete inputs for external control (DCS) and up to 128 outputs to drive rapping devices. These can be our Model SR-A1, GR-P1 and even other vibrator/rappers from our competitors.

This intelligent controller communicates via Modbus RTU or discrete signal to your DCS system or other control system. As conditions change, moisture in the fuel, varying makeup of coal, or any other environmental change, the Rappercon 900 can be adjusted remotely to run an appropriate rapping program.

To protect plugging of the catalyst honeycomb in DeNox systems by large pieces of fly ash, screens are installed ahead of the catalyst honeycomb to remove it from the gas stream. These screens will build up fly ash and become less effective. The solution is our screen rapping system. Under remote control by the DCS system the operating programs will vary to change impact forces and frequencies to keep the screens clear and manage the forces so that there is no breakage.

In the case of hopper rapping there are dedicated inputs in the rapper controller system that allow the DCS or external controller to run specific rappers on only hoppers that have the outlet valve open and running.

The operator interface is designed for simplicity and still provide all the tools for calibrating rapper force, changing programs, adjusting rapping parameters and monitor for faults. It even includes an oscilliscope function for troubleshooting as well as calibrating the rappers.

Rappercon 900 from AVC

Since 1977, the CECO AVC brand has been a leader in the development, distribution, and maintenance of Electrostatic Precipitators (ESPs) used in industries worldwide. AVC manufactures state-of-the-art voltage controllers, rapping systems, and replacement components for ESPs. AVC has become a driving force in the field by designing and building devices such as the Rappercon™ 900 Controller.

Unwanted particles removed by the Automated Voltage Controllers can accumulate and reduce the efficiency of the ESP. Our AVC rapping systems solve this issue by cleaning grounded plates and removing particulates efficiently. By doing so, ESPs can function at peak efficiency. Our rappers ensure swift and responsible disposal of fine particles in a variety of environments. We keep the gas flowing cleanly. At every stage, AVC brand has it covered.

Major industry leaders in biomass power, petroleum refining, chemical product manufacturing, and cement production come to AVC for systems and parts. If it deals with ESPs, we are the one to call.

AVC provides expert clean/dirty inspections, repairs, and upgrades to confirm and safeguard that your equipment remains on the cutting-edge. Our resources, know-how and expertise continue to set us apart in the industry. That is why we are trusted around the world in some of the most strenuous and hazardous conditions.
