Analytical sample gas lines, cut to size with PTFE inner core, available on reels of by the metre

H 300 B series120 °C

For user assembly on the construction site: H 300 B heating hoses are available as meter goods up to a length of 150 m. This makes it possible for the customer to determine hose lengths for themself "from the roll".In combination with our H 300 B-K assembly set, the end connections can be fitted on-site. Parallel heating tapes are used for heating.

The H 300 B heating hoses with HBR semiconductor heating tapes limit their power on heating. The temperature attained depends on the environmental conditions, A temperature controller may be required, depending on the application, as too high temperatures destroy the semiconductor layer. If temperature differences occur along sections of routed heating hoses, the heating power adapts to the environmental temperature from section to section. This ensures uniform heating overall.
