4.2 Types of devices
Process thermostats
The type designation of the Integral XT Process Thermostat consists of the numerical figures for the
cooling power (in kW at 20 °C, mathematically rounded) and the minimum temperature (rounded,
without arithmetical sign). The identifying letter "H" stands for devices with a maximum operating tem-
perature of 300 °C or "W" stands for water-cooled variants.
Examples: XT 750 is a device with approx. 7 kW cooling power, approx. -50 °C lowest temperature
and 220 °C highest temperature.
XT 350 HW is a device with approx. 3 kW cooling power, approx. -50 °C lowest tempera-
ture, 300 °C highest temperature and water cooling.
High-temperature thermostats
The type designation of the Integral XT High-temperature thermostat consists of the numerical figures
for the heating power (in kW, starting from 230 V devices, mathematically rounded) and an identifying
letter. The identifying letter "H" stands for high-temperature thermostats and "W" stands for water-
cooled variants.
High-temperature thermostats with cooling water connection (type W) always require a cooling water
supply, even if they are only used in heating mode.
Precise figures can be taken from the Technical Data (
