Industrial Controllers
nVent Raychem thermostats and electronic control panels operate self-regulating and power-limiting heat trace cables in hazardous and non-hazardous areas. Thermostats give simple on/off temperature control for a single circuit. Electronic control panels add monitoring, alarms, and — on the Elexant range — Modbus connectivity and ground fault protection, for sites where central monitoring of multiple circuits matters. Choose a thermostat for straightforward single-circuit freeze protection. Choose an Elexant control panel or NGC-40 multi-circuit panel where you need central monitoring, data logging, or integration with a building management or SCADA system. All units on this page are ATEX and IECEx certified for hazardous area installation unless stated otherwise.

FAQs
What's the difference between a thermostat and a control panel? A thermostat provides simple on/off temperature control for one circuit. A control panel adds monitoring, alarms, and — on Elexant models — Modbus or BMS integration, and can often manage multiple circuits from one unit.
Do I need an ATEX/IECEx certified controller? Any control equipment installed within a classified hazardous area (Zone 1/2 gas, Zone 21/22 dust) must carry ATEX and IECEx certification. Non-hazardous area installations don't require this.
Can one control panel manage several heating circuits? Yes — the NGC-40 is a multipoint panel built for exactly this, while the Elexant range is generally single-point but can network multiple units together (up to 247 on the Elexant 5010i's RS-485 bus).
What does Modbus connectivity let me do? It allows the controller to report status, alarms, and readings to a building management system or SCADA platform, rather than only local control.
