nVent RAYCHEM NGC-20 control and monitoring system

Overview

The RAYCHEM NGC-20 is a field-mounted electronic temperature control system providing local control and central monitoring capabilities for industrial heat-tracing applications.

The RAYCHEM NGC-20 is an advanced field-mountable electronic temperature control system providing local control and central monitoring capabilities for industrial heat-tracing applications. A true “Smart Thermostat”. Compared to centralised control, the RAYCHEM NGC-20 system can significantly reduce costs without compromising safety and reliability. Approved for hazardous areas, the RAYCHEM NGC-20 is also available with an integrated intelligent safety temperature limiter (SIL 2 device).

Temperatures, earth leakage and operating currents as wells other crucial data associated with heat-tracing circuit integrity is constantly monitored and reported. Both monitoring and configuration of the RAYCHEM NGC-20 can be achieved remotely via the RAYCHEM User Interface Terminal (UIT) and/or by using RAYCHEM Supervisory software application. A hand-held wireless device is also available to enable the system to be configured and monitored in the field without opening the control unit.
