Electrical Heat Traced Tubes

In this system electric heating is achieved by utilizing a resistance based heating cables, which runs parallel to the tubing,

Overview

Techwin International’s Electrical heat-traced tubing is a pivotal solution designed to help you maintain fluid temperatures flowing within tubing systems. By employing resistance-based heating cables running parallel to the tubes, this system actively compensates for heat loss, preventing temperature drops and ensuring temperatures are maintained within the tubing system. We provide a variety of Electrical heat-traced tubing solutions based on your needs and applications. Our electrical heat-traced tubing bundles are available in parallel constant wattage heating cables, self-regulating heating cables, power-limiting heating cables, series heating cables, etc.

Advantages

Installation is both time and cost-efficient for laying an energy cable.
Our Electrical heat-traced tubing can be supplied in very long lengths, minimizing waste and reducing the need for numerous fittings.
They are simpler to assemble and have space-saving designs.
Our Electrical heat-traced tubing is maintenance-free with robust protection against mechanical, abrasive, and corrosive damage.
They are Suitable for use in hazardous areas

Types

1. Electrical traced tubing with constant wattage heating cable

Techwin International’s Electrical Traced Tubing with Constant Wattage Heating Cable is engineered to sustain temperatures up to 200°C, with a maximum exposure limit of 260°C. Their key benefits are:

Precision-cut lengths to meet specific requirements,
Consistent power output
There’s no need for circuit breaker oversizing as there’s no inrush current at startup.

2. Electrical heat traced tubing with Self regulating heating cable:-

The Self-Regulating Heating Cable option maintains temperatures up to 121°C and withstands exposure up to 250°C. Their key benefits are:

Automatically adjusts power output in response to temperature changes,
Significantly reducing the risk of overheating.
Cut to length for your precise needs.

Keynotes

Applications

Analyser Sampling Lines
Process Analysers - Emission Monitoring Systems - Gas Chromatographs

Flow Transmitters - Pressure Transmitters - Level Transmitters.

Rating & Performance

Our Electrical Traced Tubing is designed to meet the highest industrial performance standards. The rating encompasses a dual focus on safety and functionality, ensuring that even under the stress of continuous operation, the system performs with exceptional reliability.

Insulation

Our standard non-hygroscopic fiberglass insulation effectively prevents moisture ingress and thermal loss. For extreme conditions, where temperatures soar above 400°C, aerogel insulation offers superior thermal protection without compromising performance.

Outer FR-PVC Jacket

The robust outer FR-PVC jacket of our tubing ensures is UV resistant and can sustain a spectrum of environmental challenges, including water, oils, and various chemicals. Its resilience is proven against temperature fluctuations from a frigid -40°C to an intense 105°C.
