Isopad Heated hoses

Applications

Many products are heated in containers or processes to improve their flow characteristics or homogeneity. Moving these materials between processes or from storage vessels can be problematic as rigid pipe work combined with cumbersome heating methods, can be undesirable at best and is often impossible. Isopad heated hoses solve these issues by seamlessly blending industry standard hoses and fittings with world leading heating technology, into a flexible hose with integral heater and sensor.
Isopad hoses are designed and manufactured to optimise heat uniformity and control characteristics using an integrated temperature sensor and an evenly distributed resistive heating element. Decades of engineering experience ensure the hose will maintain the medium being transferred at an even, pre-set temperature, avoiding hot spots or changes in viscosity, eliminating condensation, degradation and crystallisation. The flexible properties of the heated hose eliminate many problems with alignment and machine vibration.

Key Benefits

  • Process temperature up to  400° C with short heating times.
  • (Applications spectrum also for irregular shapes.)
  • Customized design.
  • Easy assembly.
  • Highly efficient solutions with a perfect combination of performance, insulation and temperature control.
  • Energy efficient layout by customized design.
  • Long lifetime thanks to the continual high quality of fabrication and optimized control of the heating cables.
  • Complete order processing and production of heating cables and heating tapes in Heidelberg (Made in Germany)

Technology

The inner hose is in direct contact with the liquid or gas. Standard hoses are made of high-quality polytetrafluoroethylene (PTFE) which exhibits many characteristics that make it the ideal choice from a very low coefficient of friction to high chemical resistance and a temperature range from -70°C to 250°C. Other materials can be used to manufacture hoses for specific applications.
Stainless steel braid is required for high pressure use. The PTFE inner hose is provided with a
stainless steel braid. Up to 3 layers of braid can be applied to increase the operational pressure up to 500 bar @ 24°C (6 mm diameter inner).
The heating element is carefully wound around the hose at a constant predetermined pitch to ensure
accurate and uniform heat density.
The temperature sensor ensures accurate system control. Isopad heated hoses have an integral sensor and several types are available e.g. Pt100 resistance temperature sensor, type K thermocouple, type N thermocouple.
The heating element is protected by a fleece lining and the sensor pitch remains unchanged during the repeated manipulations the hose will endure in operation.
Insulation material and thickness is calculated to minimise heat loss and ensure that the temperature specified by the client is achieved and maintained.
Braid is not only aesthetically pleasing but it’s also designed to ensure that the insulation material remains undamaged and firmly held in place as well as meeting the static and dynamic bend requirements of the client.
The end cap with cable entry has dual use, firstly to ensure the hose remains intact in  operation and secondly it provides a secure and convenient location for both the power and sensor connection cables.
