Heated hose, standard range for liquid and gaseous media IHH-ST4A/ST4D

Isopad IHH-ST4A/ST4D

is a flexible heated hose for liquid and gaseous media with a maximum operating temperature of 400°C. The standard versions have corrugated stainless steel inner hose constructions with stainless steel braiding for pressurized operation.
The thermal insulation consists of high temperature fleece and silicone foam. Mechanical protection is provided by a stainless steel braid and soft ethylene propylene diene monomer (EPDM) endcaps. Built-in Pt100 sensors provide optimum temperature control The evenly wrapped resistance heating cable allows an homogeneous heat distribution throughout the hose. The standard
