The Cleaver-Brooks Accu-Draft is a stand-alone, stack draft control system designed to maintain stack draft on set point throughout the firing range of the boiler. Can be used on new equipment or applied to existing equipment as a field retrofit. The C-B Accu-Draft works with various C-B damper assemblies that include a low draft switch, draft transmitter, and damper actuator. The HMI included makes the C-B Accu-Draft’s operation and setup easy and operator-friendly. Other customized solutions are available to meet other more sophisticated installations.

The ADAC is a PLC-based deaerator and surge tank control system designed to optimize the delivery of feedwater to the boiler ensuring steam reliability and higher operating efficiency. It can monitor and control all points on a deaerator or surge tank and be adapted for the many different boiler systems in modern steam plants. The ADAC provides pump control via on/off or variable speed drives, functions as overall tank controls by monitoring and adjusting multiple input valves, condensate return, fresh water make-up, and emergency make-up to maintain consistent water level without overflowing. The ADAC also controls the steam pressure to properly maintain water temperatures and ensures water quality is maintained, extending the life of your boiler. It can communicate data to most BAS systems and/or the C-B Master Panel. The ADAC’s interface puts the control of the deaerator or surge tank at your fingertips with its user-friendly menu system and screens.

The LCS control system was designed to provide easy level control for deaerators and atmospheric surge or condensate tanks. By utilizing a simple PLC platform, the LCS is configurable to adapt to a number of different system configurations. The LCS250 offers two-tank level control. Single Tank Level Control: The LCS 150 system accepts a 4-20 mA input for use as a level signal. Data is available via Modbus RTU communications or logged to an optional Micro SD card. Setup and control are easy with the LCS150’s interface user-friendly menu system and setup screens. The LCS is a great entry-level control system, and is ideal in situations where electronic level control is preferred over mechanical level control.
The LCS 250 is used when level control is provided for the deaerator tank while the surge tank receives feed control, with a bias to limit the valve position according to surge tank level. The system accepts a 4-20 mA input signal from each of the deaerator and surge level transmitters. Data is available via Modbus RTU communications or logged to an optional Micro SD card. The LCS250’s interface puts the control of the level control of a single tank deaerator and surge system at your fingertips with its user-friendly menu system and screens.

The PCS is a simple pump control system with lead/lag sequencing on a timed rotation, “first on first off” basis, or manual rotation (user-selectable). Pumps are turned on or off as required to maintain a pressure set point within a user-configurable deadband. The PCS can control from 2 to 4 pumps for either on-off or VSD control. Data is available via Modbus RTU communications or logged to an optional Micro SD card.
