Heated Hoses

Heated Hoses

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 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.


Inner hose is in direct contact with the liquid or gas. Standard hoses are high-quality polytetrafluoroethylene (PTFE) which exhibit many characteristics that make it the ideal choice from a very low coefficient of friction to a high chemical resistance and a temperature range of -70°C to 250°C. Other materials can be used to manufacture hoses for specific applications.

Stainless steel braiding is required for high pressure use. The PTFE inner hose is provided with a stainless steel braiding. Up to 3 layers of braiding can be applied to increase the operational pressure up to 500 bar @ 24°C (6 mm diameter inner). Heating element is precisely wound around the hose at a constant predetermined pitch to ensure accurate and uniform heat density. Temperature sensor ensures accurate system control.
Isopad heated hoses have an integral sensor, several types are available e.g. Pt100 resistance temperature device, type K thermocouple, type N thermocouple. Fleece ensures the heating element and sensor pitchremains unchanged during the repeated manipulationsthe hose will endure during operation. Insulation material and thickness is calculated to minimise heat loss and ensure the maintain temperature specified by the client is achieved.
Braiding is not only aesthetically pleasing but it’s also designed to ensure the insulation material remains undamaged and firmly held in place as well as meeting the static and dynamic bend requirements of the client. End cap with cable entry has dual use, firstly to ensure the hose remains intact during operation and secondly it provides a secure and convenient location for both the power and sensor connection cables.
