Heated Analysis Lines for Exhaust measurements

are used in analytical equipment installed to monitor air pollutants and for process analysis in industrial facilities. The range of application also comprises engine test benches for the development of combustion engines as well as mandatory emission tests and vehicle certification. These heated lines enable the transport of gas samples from the sampling point to the gas treatment system and analyser without falsification of measuring values. They offer reliable service 24/7 over many years, even under tough conditions.The accuracy and repeatability of sensors and instruments in analytical equipment crucially depends on the treatment of the sampling gas and thus on the correct heating of the measuring gas conduits in accordance with applicable standards and regulations. Therefore, the heating within an analysis system is an important component of the entire measuring unit. With support of the specialists from Winkler, you can easily find the perfect solution for your particular requirements.

Heated Lines series WAKG + WAKS

  • Special installation tool and thread paste included with initial delivery
  • Heating with  fluoropolymer insulated heating cable with protective braiding
  • Flexible insulating structure with multilayer thermal fleece and sturdy protective hoses in different versions or with flexible silicone foam and protective braiding in different versions.
  • Built-in sensor for the operation with a controller
  • Ready to connect with multi pole plug

Connection system "Quick-Lock"

For quick assembly of heated lines. Used at dynamometer and engine test beds for carriage of measuring gas into the analysing room safe and conforming to standards.

  • Rugged structure made of high quality materials. The system is designed for sustained operating temperatures of up to 200°C.
  • Seamless (conforming to standards) heating without cold spots between the wall bushing and the heated line and the heated line coupling

Standard basic hoses and fittings

Available basic hoses and fittings for heated lines of the types listed. Depending on design, basic hoses with PTFE hose can be employed for fluid temperatures up to 250°C. Heated lines with stainless steel tubes and corrugated stainless steel tubes are designed for higher fluid temperatures, depending on the type of insulation. Higher temperatures and special solutions available on request.

Spiral Hose Guards

Spiral Hose Guards are used for the protection and bundling of hydraulic and pneumatic hoses, electric cables etc. They are also useful to reduce the contact temperature of heated lines and heated hoses in applications with high temperatures. A spiral hose guard increases the security and durability of hoses, lines and cables.
