PTFE Chemically Inert Heated Hose with Stable Heating Performance for Gas Sampling Lines

Condensed moisture in a sample line can ruin measurement accuracy and corrode analyzer components. This Heated Hose keeps sample gas above its dew point from the sampling point to the analyzer inlet, serving continuous emission monitoring systems, flue gas pretreatment units, online monitoring stations, and laboratory testing equipment. Working as a flexible electrically heated hose for temperature-controlled gas transfer, it protects measurement integrity in both fixed installations and portable sampling setups.

Sample gas passes through a PTFE inner tube that neither reacts with nor absorbs the media being measured, so what enters the analyzer is exactly what left the stack or process. A continuous heating element runs the full length of the hose, and quality insulation holds that temperature steady while keeping the outer surface safe to handle. The reinforced, pliable construction tolerates repeated bending and folding—important for lines that get moved, coiled, and rerouted during routine operation and maintenance.
