Electronic Thermostat Controls Temperature In Hazardous Areas

Pentair launched the Raychem ETS-05, an electronic surface-sensing thermostat for hazardous areas. The Raychem ETS-05 thermostat provides temperature control and monitoring for heat-tracing installations. Compared to previous electronic thermostats, it provides an increased maximum current load, bigger connection terminals, a broader temperature control range, local LED indications and an additional fail-safe option, according to the company.

The increased size of the thermostat’s terminals to 6mm2 enable power and heat-tracing cables to be connected directly, eliminating the need for junction boxes. Raychem ETS-05 is available in two versions: the ETS-05-L2-E monitors temperatures up to 199°C and is fitted with a flexible sensor, while the ETS-05-H2-E can be used for temperatures up to 499°C and has a stainless steel sensor. Both come with a maximum nominal current of 32 amps for longer circuits to meet the market’s requirements. Other features include switching accuracy of ±1K at 5°C and switching differential (hysteresis) of 3°C.

The thermostat has a configurable failsafe mode (power on or power off). It has a LED local status indicator, which shows whether the device itself as well as the heat-tracing cable is switched on or off. In case of sensor failure, the thermostat will switch to an on or off state, depending on the user’s requirement. The LED will show the alarm state at that moment. Raychem ETS-05 is fully compliant with ATEX and IECEx requirements for use in ZONES 1, 2, 21 and 22.
