nVent RAYCHEM SBS-xx-Hx-ECO-10 Control panels for Hot Water Temperature Maintenance systems

Overview

Multi-Circuit control panel

The SBS-XX-HX-ECO-10 control panel for hot water temperature maintenance systems provides a totally integrated solution for the control of RAYCHEM self-regulating heating cables for single pipe hot water temperature maintenance applications. The control panel comprises the energy efficient HWAT-ECO control system with integrated standard, economy, and “Tap time” set-back timer functions.

The control panel also includes monitoring of the boiler output temperature and low temperature alarm in the event of low boiler output temperature. A BMS connection is provided to allow controller override switching between maintain mode, setback mode, or legionella prevention mode (when using HWAT-R heating cable only).

SBS-06-HV-ECO-10 and SBS-09-HV-ECO-10 includes additionally an integrated time shift logic module for phased switch-on of the heating circuits to prevent in-rush surges when the circuits are activated.

The SBS-XX-HX-ECO-10 panels switches up to 9 circuits of HWAT-L or HWAT-R self regulating heating cable. The panel also includes electrical circuit protection devices (C-type circuit breakers and RCD protection) for safety and peace of mind.

Key benefits:
  • Integrated electrical safety, control, and heater connection of multiple heating circuits from the heat tracing manufacturer.
  • Alarm function for system monitoring.
  • BMS input available.
  • Boiler monitoring sensor for low temperature alarm.
The panels need only be connected to the 400Vac (3 phase) supply.
