At Castlet, we provide a complete range of products designed to filter emissions and control outputs across various industries. Our Electrostatic Precipitator (ESP) solutions are built on an engineering legacy of over 50 years of innovation and expertise.  

We provide design, manufacture, installation, and support of power and control equipment for ESPs, including HV Transformer Rectifiers, HV Control Cubicles, automatic voltage controllers (AVCs), Earthing Switches, and ESP Controller Retrofits to optimise particulate capture and emissions control. 

Industries such as fossil fuel power generation, cement & metals, minerals, waste and glass manufacturing use ESPs to ensure reliable, compliant, and efficient particulate control. Castlet works with all of these industries to help manage their air pollution levels and optimise emissions outputs.

The MCS III Controller Family represents the latest iteration in a long string of controllers for ESP power and control equipment produced by Castlet. The MCS III automatic voltage controller units incorporate industry-leading technology for superior air and particulate control, built on comprehensive design, prototyping, manufacturing and testing.  

Controller hardware and software can become obsolete or unsupported over time. Retrofits upgrade ESP controllers to modern standards, improving reliability, reducing downtime, and extending the lifespan of the ESP system. 

Effective ESP power and control can provide many benefits for plants, including improved reliability and uptime, enhanced particulate capture performance, reduced maintenance costs, and tailored designs suited to each plant’s operational environment. 

Castlet offers spare parts, calibration, maintenance, optimisation, retrofits, and remote/online support, as well as emergency callouts to ensure continuous, reliable operation of ESP equipment. Find out more about the services we offer.
