nVent RAYCHEM Raystat EX-02 is an ATEX certified  explosion proof EEx d rated surface sensing thermostat to provide temperature control for electric heat trace heating (EHT) systems for Raychem BTV, QTVR, XTV & KTV heat trace heating cables. It provides temperature control for all Raychem BTV, QTVR, XTV, KTV and VPL heat trace heating cables. The switching temperature range of -4°C to +163°C is adjustable externally to the EEx d enclosure by a dial mounted under a bolted-on cover and seal. The 3 metre long stainless steel fluid filled capillary and bulb give a wide range of freedom to locate the thermostat remotely from the temperature contact area.

nVent RAYCHEM Raystat EX-02 is typically used in installation application which might include; frost protection also known as frost prevention , frost heave prevention, or process temperature maintenance, long pipeline heating or tank heating with a relatively narrow temperature band
