CT Series

CT Series

The CT Series linear damper drive was designed specifically for fuel air and auxiliary air applications on CE / Alstom / T-fired / Corner-fired boilers. The CT Series provides excellent and efficient control of the Secondary Air within the windbox and will withstand the extreme heat and vibration common in this application. Effective windbox control will reduce NOx and minimise carbon monoxide (CO) associated with poor fuel-air mixing and will maintain boiler thermal performance.
