Product specifics

The ETC6350 Deaerator Controller is the latest addition to ETC’s controller range. An advanced controller developed to provide dedicated control of deaerator tanks within steam generating boiler systems. It manages the key parameters required for effective deaeration, helping to protect equipment, improve efficiency and support long-term reliability.

The ETC6350 is engineered to precisely manage a deaerator tank’s removal of dissolved gases such as oxygen and carbon dioxide from feedwater – a primary cause of corrosion in boiler systems. It provides closed loop PID control of tank water levels, maintaining consistent performance under varying loads. Continuous monitoring of high and low level limits provides early warning of abnormal conditions, helping operators respond quickly and avoid disruption.

The ETC6350 maintains accurate PID control of tank steam pressure with configurable high and low pressure alarms to safeguard equipment and support stable performance. Integrated temperature monitoring helps ensure effective deaeration while high and low temperature alarms provide clear indications of any deviation from expected operating parameters.

The ETC6350 also manages key mechanical functions within a deaerator system. Automated overflow valve control prevents overfilling and reduces water loss, while integrated transfer pump control supports up to two pumps with automatic duty and standby changeover, improving resilience and reducing the risk of unplanned downtime.

Designed with integration in mind, the ETC6350 supports Modbus RTU communication as standard for easy connection into wider plant control architectures. When paired with the ETC6076 touchscreen HMI, it also enables VNC, Modbus TCP and 4G communications for intuitive local control and secure monitoring.

With its focus on reliability, flexibility and ease of use, the ETC6350 Deaerator Controller provides a robust solution for modern deaerator tank control. Its advanced control capabilities, integrated safety features and communication flexibility make it a valuable addition to any steam plant seeking consistent, long-term performance.
