Castlet provides a comprehensive service to test the signals from transformer rectifiers (TRs), both during hot and cold running, ensuring the MCSIII controllers are accurately calibrated. This is essential in ensuring that single phase and three phase TRs continue to provide stable power for Electrostatic Precipitators (ESPs). 

This service helps maintain accuracy and system integrity across complex industrial environments. Our capability extends to both current and legacy equipment, such as single phase power equipment for ESPs. 

Castlet’s calibration services support heavy industrial operations where precision, compliance, and system reliability are critical. We work with clients across industrial manufacturing, power generation, automation, nuclear, energy management and more sectors. 

Our service is particularly valuable for large industrial environments operating complex or safety-critical systems where a lack of control in ESP power can have significant operational or regulatory consequences. 

Regular calibration ensures that equipment continues to perform accurately and reliably over time. As systems age or operate under demanding conditions, measurement drift can occur, leading to reduced efficiency, inconsistent performance, or compliance risks. Our calibration service addresses these issues before they impact operations. 

Calibration can be performed as part of a proactive maintenance visit. Together, these services provide a complete approach to system integrity. 

We deliver calibration services with a strong focus on technical accuracy, reliability, and practical industry experience.  

Our engineers understand how equipment interacts within larger control and process environments, ensuring calibration activities reflect real operational conditions. 

If you want to ensure your entire system continues to operate with confidence, precision, and long-term reliability, get in touch with us today.
