Eltherm Heated Hoses

Eltherm Heated Hoses

Industrial & Hazardous Area Heated Hoses

---

Thorne & Derrick are authorised suppliers of Eltherm heated hoses—engineered to maintain precise temperatures for fluids and gases in process-critical operations. Designed for use across a wide range of industrial sectors, Eltherm heated hose assemblies deliver performance, flexibility, and compliance with international safety standards, including ATEX and IECEx.

Eltherm heated hoses are the ideal solution for the reliable transfer and transportation of liquids or gases without any loss of heat in both safe and hazardous areas. The required maintenance temperature, power, application and outer protection material will determine the product selected.

Typical applications include gas analysis, hot melt machines, bitumen transfer lines, heavy oil transfer, and wax processing equipment.

Gas substances are typically channelled between the measurement point and the analysis instrument in the analysis technique, such as in refineries, flue gas, mechanical engineering, the chemical industry, and the motor industry. For many applications, the gas must have freeze protection, be protected against condensation, or guarantee a constant temperature of up to 250°C.

Types Of Eltherm Heated Hose

1. Analyzer Hoses—specified to provide temperature maintenance and frost protection up to 450° Celsius on hose diameters 4-10mm.
2. Industrial Heated Pressure Hoses—to provide temperature maintenance and frost protection up to 250° Celsius on hose diameters 8-100mm.

All hoses are designed and produced specially to customer specifications – contact us with your requirements.

Controlled analytic heated hoses

This type of heated hose is installed to transport and transfer gaseous media from the point of withdrawal to an analytic measuring device – the hose is fixed-mounted in plants or in the form of portable systems.

Heated Pressure Hoses

This type of heated hose provides process heating to maintain a constant temperature and transfer hose contents with our heat loss. Typical media include oil, wax, resin, tar, paint, grease, water, glue, plastic and foodstuffs.

Eltherm Product Benefits

Eltherm heated hoses are engineered to deliver reliable thermal performance in demanding industrial environments. Designed for precision, safety, and adaptability, they ensure consistent temperature maintenance for a wide range of process applications.

Spatial density in the hose that carries the heating cable ensures perfectly homogeneous heat distribution throughout the hose in addition to optimum element loading.

The additional glass fibre spacer serves to prevent hot spots in moving applications with greater bending strain, as contact between the heating cables is avoided.

Other key advantages include:

• Precise temperature control for critical fluid and gas handling

• ATEX & IECEx certified for use in hazardous areas

• Custom-built to suit application-specific requirements

• Durable construction with chemical and mechanical resistance

• Integrated sensors for thermal monitoring and control

• Energy-efficient insulation reduces heat loss and costs

Applications

Eltherm heated hoses are suitable for a wide range of industrial applications, including:

• Chemical and petrochemical transfer

• Emissions and gas analysis

• Adhesive, sealant, and resin dispensing

• Food-grade fluid handling

• Pharmaceutical production

• Freeze protection in outdoor installations

• Paint and coating processes

Analytic Hoses

ELTHERM ELHa

Eltherm-controlled analytic heated hoses serve to transport gaseous media from the point of withdrawal to the analytic measuring device. In most cases they are fixed-mounted in plants or in the form of portable systems.

One of their primary functions is in officially mandated emission monitoring in power stations or waste incineration plants. The range of Eltherm analytic hoses are also increasingly used in process analytics by various industries, including petrochemical, oil and gas.

Key benefits of the Eltherm analytic hoses include:

• Transport of gaseous media without loss of temperature
• Operating temperatures 5°C – 450°C
• Nominal hose widths: 2mm – 12mm
• Hose length: 0.3m – 150.0m
• Voltage: 12V – 400V
• Heat output optimised for each application
• Great heating circuit lengths
• Hose heating cables produced in-house

Analytic Heated Hose

Product Components

1. Inner Liners – there are a range of liners available for the Eltherm analytic hoses – these are chosen dependent on the temperature required.
2. Sensor – temperature sensor is mounted between the inner lining and heating cable for temperature control. Additional sensors can also be mounted in any position required for further temperature detection and monitoring.
3. A – Heating cable – the resistance heating cable is produced in-house and is the basic heater element. The cables are insulated with fluoropolymer. 3.B – Spacer – The spacer is manufactured from braided glass fibre and provides reliable protection for the heating cable against damage and hot spots in the event of bending strain.
4. Insulation – insulation depends on the maximum operating temperature and the selection of the heater outer jacket.
5. Outer Jacket – selection is determined by the application, bend radius and ambient temperatures. The outer jacket provides reliable protection from humidity, weather, external environmental impact and mechanical strain.
6. End caps – used to seal off both ends, and the integrated strain relief provides reliable relief for the connecting cable.
7. Connecting fitting – connection to the analyser or probe
8. Connecting cables – by default, the connecting cable is led out separately.

Hazardous Area HEATED HOSES – ATEX CERTIFIED

Eltherm explosion-proof heating hoses are used for the transportation of liquids or gases within hazardous areas without any loss of temperature and are certified for use in Zone 1 and Zone 2 location hazardous areas.

The process temperatures range from 5°C (frost protection) to 200°C, and each heated hose is configured according to individual customer specifications. The entire system is hazardous area certified for use and only EC type-tested individual components are selected.

Anti-static outer jackets are used throughout the chemical, petrochemical and pharmaceutical sectors in addition to plant engineering and power stations.

Common areas of application include process control and control systems as well as monitoring of air-conditioning systems.

Automotive & Robotic Industry

Heating products for applications within the automotive and robotic industries, such as securing car windscreens. Car windscreens are secured using a hot adhesive applied using a robotic arm; this glue must be maintained within a specific temperature range to provide optimum adhesion and is delivered by industrial hose.

ONSHORE & OFFSHORE Oil Pumping

Heated hoses reduce viscosity of heavy oil to enable this to be pumped between containers and transporters with ease in safe and hazardous areas – electric products can be used with light oil in areas with severe winter and freezing conditions.
