Heated Sample Lines (up to 450°C)


  • Transport of gaseous media without temperature loss
  • Heat output optimised for application
  • Great heating circuit lengths
  • Heating cables produced in-house
  • With integrated filter upon request

Dpstar is one of the leading suppliers of heated hoses / flexible heated lines. Whether freeze prevention or temperature maintenance: We ensure transport of liquid and gaseous media without loss of temperature. They are customized to reach the required temperature and match specifications. There are different temperature ranges up to 100 °C, 200 °C, 250 °C or 450 °C.

Design of a Heated Hose

A Dpstar heated hose is individually designed and produced according to customer specifications. Our in-house development department will be pleased to implement your requirements and find a tailor-made solution. Heated hoses always consists of an inner liner, temperature sensor, heating conductor, insulation, outer jacket, and an end cap. By means of a temperature sensor the information about the temperature can be processed and the heated hose can be operated via the controller. They are therefore a component of the entire heated hose. Whether fittings are installed depends on the application, the operating pressure, and temperature. In addition to the connection fittings, hose- or pipe protrusions are also possible. Of course, Dpstar offers a flexible heated hose that can be used in hazardous areas.

You can choose from various materials according to your requirements. For example, an outer jacket as a corrugated metal hose made of stainless steel is mechanically more robust and for higher temperatures. A silicone outer jacket is washable and for more flexibility and smaller bending radius. We focus on individuality, each heated hose is designed and produced according to specific customer specifications. For high-pressure applications, fluoropolymer and polyamide materials are used. With our products we can offer a solution for almost every application. Each heated hose line has an integrated trace heater (regulated or self-regulated) and thus ensures optimum heating of the medium.

Heated sample lines are used to transport gaseous media from the sampling point to an analytical measuring device. In most cases they are permanently installed in plants or in the form of portable systems. A main field of application is the emission monitoring required by the authorities, e.g. in power plants or waste incineration plants. Our heated analysis lines are also used in process analysis in various branches of industry, e.g.: the chemical and petrochemical industry, where one of their functions is the monitoring and control of combustion processes. Heated analysis lines are also used in engine test benches for combustion engines.
