RBC (Loss of Rotation)

INDUSTRIAL GRADE QUALITY, FOR ROTATING BIOLOGICAL CONTACTOR, WATER TREATMENT PLANTS

Built using industrial switchgear, our loss of rotation panels are designed to last, often used to replace PCB panels that typically have a shorter life span.  

​

Compatible for most rotating sewage treatment plants from Klargester, Kee, Marsh, Harlequin and others.

 

Available for both gravity systems and pump systems.

Designed for Reliability

Available up to IP66 GRP enclosure suitable for outdoor applications or mild steel enclosures to be mounted inside a kiosk. Beacon terminals come as standard for easy connection, and we also offer beacon guards for added protection on site. An adjustable timer is built in as standard too, allowing you to set different revolution speeds with ease.

Practical Where It Matters

The Loss of Rotation panel offers built-in volt-free relays for both motor trip and rotation failure — making integration with your alarm or BMS system fast and fuss-free. And thanks to the door interlocked isolator, safe access is ensured every time.​​​

​​

Need more than just detection? These panels can be configured as rotation-only, or supplied with pump power included — ideal for setups where a permanent supply is needed, such as pumps with built-in float switches. We can also provide float switch inputs directly on the panel, and the reed switch if required.
