Thermon Terminator ZT - Hazardous Area Pipewall Sensing Thermostat

Hazardous Area Pipewall Sensing Trace Heating Thermostat

The Thermon Terminator ZT is a hazardous area thermostat designed to provide adjustable control for frost protection and temperature maintenance trace heating applications which require pipewall or tankwall temperature sensing.

The Terminator ZT is available with 4 different temperature control and bulb exposure temperature ranges and also has two variations.

The ZT-WP is designed to be wall mounted as standard, or pipe-mounted using a XP-1 stainless steel mounting bracket and has a PVC coated galvanised steel flexible capillary armouring complete with capillary gland and insulation entry device.

The ZT-XP includes an expeditor to allow for the thermostat to be installed directly onto the pipe and allows for two heating cables to enter and be connected within the enclosure.

Terminator ZT thermostats are suitable for either safe or ATEX Zone 1 and Zone 2 hazardous applications and have an IP rating of IP66.
