The Raystat EX-04 is an EEx e approved ambient sensing thermostat to provide temperature control for electric heat tracing (EHT) systems with Raychem BTV, QTVR, XTV & KTV heating cables. It is approved for use in ATEX hazardous areas. Benefits include, easy installation and commissioning, low cost installation and relative accurate control.
The nVent RAYCHEM ETS-05 electronic surface sensing thermostat provides accurate temperature control for heating cables. The ETS-05 is available in two versions. The ETS-05-L2-E is for temperatures up to 199°C, while the ETS-05-H2-E can be used for temperatures up to 499°C. The maximum nominal load is 32 A for both thermostats. Temperature setting is accurate via digital rotary switches inside the enclosure. The ETS-05 has a LED indicator which indicates the status of the thermostat (powered on/off), the status of the heat-tracing cable (powered on/off) and the status of the sensor. In case of sensor failure the thermostat can switch to an on or off state, depending upon the users requirement.
