Watlow® Achieves IECEx ‘d’ Certification on Series ‘F’ Flange Immersion Heaters Manufactured in its Shanghai, China Facility

24 February, 2015

St. Louis, MO – Watlow®, an industry leader in the design and manufacture of complete thermal systems, announced that its Series ‘F’ Flange Immersion Heaters manufactured in its facility in Shanghai, China received the IECEx ‘d’ flameproof certification.

The principles of the IECEx ‘d’ 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 and flexible walls are not permitted. Achieving the IECEx ‘d’ certification provides Watlow customers a guarantee that the products they are buying are safe.   

“Agency certifications, such as the Ex ‘d’ flameproof, are important achievements because certification marks are our customer’s assurances that our products meet rigorous standards for safety and reliability,” said Samir Dorle, director of operations and supply chain, Asia.

Watlow’s flange heaters are designed for heating liquids and gases in tanks, pressure vessels, vaporizers and similar for applications from 40 to 4,000 kilowatts. 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. Whenever an indirect or direct heat exchanger is needed, contact Watlow to solve your application needs.
