Watlow® augmente la température nominale du boîtier grâce à sa certification IECEx ‘e’ pour les éléments chauffants à bride tubulaires

Watlow®, an industry leader in the design and manufacture of complete thermal systems, announced that it recently completed a project to increase the temperature of its enclosure and flange rating from +80°C (176°F) to +115°C (239°F) on its IECEx ‘e’ certification for tubular flange heaters.
Increasing the temperature rating of the original IECEx ‘e’ certification is attractive to many of Watlow’s customers, especially for those working on projects installed in hot environments. The higher enclosure ratings can eliminate the need for additional convective cooling features, additional insulation features and the need for sun shade, which can lower overall system costs.
“Many of our competitors have an enclosure temperature rating that is the same as their ambient temperature rating,” said Dennis Long, director of marketing, energy processes business unit. “Since Watlow’s enclosure rating has been increased, a likely result is less expensive system design.”
The IECEx ‘e’ certification indicates increased safety protection for the enclosures of tubular flange process heaters.
The principles of the increased safety protection concept are: no sparking contacts; no semiconductor devices (the failure mode is not possible to ascertain); no hot surface above temperature class; high integrity electrical connections; increased creepage (distance over insulation surface) between live parts and to earth potential; increased clearance distance (through air) between live parts and to earth potential; and high quality materials that have a rated continuous operating temperature of at least 20°C greater than that achieved under rated voltage and at maximum ambient conditions. Achieving the additional IECEx ‘e’ certification provides Watlow customers a guarantee that the products they are buying are safe.
“Agency certifications, such as the Ex ‘e’ increased safety protection, are important achievements because certification marks are our customer’s assurance that our products meet rigorous standards for safety and reliability,” said Jeff Knobloch, product manager.
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.
