HUBER offer ATEX rated solutions for the Unistat® range.

In addressing the complexities, restraints and demands of ATEX zones 1 & 2, Huber offer two solutions for use with the Unistat range of temperature control systems.

The first option consists of a water cooled Unistat installed in an Ex-p pressure encapsulated ATEX rated cabinet according to EN 60079-2 (Ex px II T4).

The Ex-p cabinet is made from stainless steel with a sealed double door and provides a neutral shelter as part of a complete system in areas with possible explosive atmosphere. Compressed air is pumped into the cabinet purging it of any potentially dangerous vapours and creating a pressure slightly above atmospheric level.

The Unistat is operated by the Unistat pilot. A thin plastic membrane covers the face of the pilot, sealing it inside the pressure chamber, allowing the Unistat to be operated by the touch screen and encoder.

The second option is an ATEX certified remote controller, which can be located in the ATEX zone for convenient operation of the Unistat situated in the safe zone. The ATEX remote controller conforms to ATEX class II 2G Ex ib IIC T4.

Combined with the Unistat’s hydraulically sealed, low volume fluid circuit and Huber’s knowledge of thermal transfer and temperature control, an ATEX certified system is available that provides rapid and responsive temperature control for even the most aggressive and demanding applications, from -120°C up to 300 °C.
