Watlow®, an industry leader in the design and manufacture of complete thermal systems, has announced that its tubular flange heater product has received additional IECEx ‘d’ flameproof certifications. A partial list of the available features now includes capability for Ex d IIC: T1-6 Gb, up to +80°C (176°F), enclosure / anti-condensation heaters and IP66.
The principles of the flameproof concept are:
- No external hot surfaces above the temperature class.
- Design of the enclosure joints must comply with the requirements of the standard.
- Parts fitted inside an enclosure may include sparking contacts, semiconductor devices and batteries.
- Flexible walls are not permitted.
Achieving the additional IECEx ‘d’ certification provides Watlow customers a guarantee that the products they are buying are safe.
Watlow’s flange heaters are designed for heating liquids and gases in tanks, pressure vessels, vaporisers and similar for applications from 40 to 4000 kW. They are made with WATROD or FIREBAR tubular elements brazed or welded to a flange.
Typical applications include a variety of thermal processes in the oil, gas and power generation industries.
