Analytical heating hose with self-limiting power
HX3B series120 °C
The self-limiting analytical heating hoses is designed for use in Ex areas. The heating hoses are above all characterised by their compact construction with internal connection configuration. The HX series heating hoses are tested to ATEX standards and with an EC type examination certificate they are certified for the entire heating hose.
The specially structured HX3B series heating hoses can be used in temperature classes T1 ... T6 depending on the temperature control and are suitable for use in zones 1/2 (gas) and zones 21/22 (dust). Their operation in zones 0 and 20 is not permissible.
The HX3B series industrial heating hoses can be deployed, even without temperature regulation, as a consequence of their self-limiting characteristic. The maximum final temperature must be monitored with controllers dependent upon the application.
Applications: Maintaining temperature and avoidance of frost and condensation (motor exhaust fumes, CO 2 measurement, measuring samples, industrial gases, air & environmental measurements) in Ex areas.
