IHH-ST4A/ST4D
Features
- Tmax 400°C
- Up to 150 W/m
- IP54
Application
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 for the medium. The evenly wrapped resistance heating cable allows an homogeneous heat distribution throughout the hose.
The standard versions can be used for a wide range of applications. Special designs are available on request with focus on the performance level and/or environmental influences.
Options for customized designs
If your requirements are not met by the above specifications, we can tailor-make a heated hose to suit you.
Variations depend on design and can include:
- Other nominal sizes and inner hoses, e.g. supplied components for individual heating
- Lengths up to 120 m
- Sensor types, e.g. thermocouples Type K, Type J, etc.
- Supply voltage up to 400 V, single-phase or three-phase
- Higher power outputs
- Increased ingress protection, e.g. IP65 for outdoor applications
- Increased pressure resistance, up to 475 bar at 100°C (depending on nominal diameter)
- Other materials, e.g. for applications recommending silicone free production
- Approved components for the use in hazardous areas according to IECEx and ATEX
- Replaceable inner hoses for nonpressurized gas analysis
- Premounted plugs and special supply and messenger leads
- Controlling devices and high temperature lock-out thermostats
