Analytical heating hose with constant power

HX3 series100 °C / 200 °C

The HX3 series analytical heating hoses with Ex heating conductor is designed for use in Ex areas. The heating hoses are above all characterised by their compact construction with 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 HX3 series heating hoses can be used in temperature classes T1 ... T3 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 HX3 series analytical heating hoses are equipped with two EX-PT100 . PT100 Exi intrinsically safe are also optional.

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.
