Electric heat exchangers that operate in hazardous locations now have a broader range of IEC SP-892 Ex eb certifications, according to Watlow.

IECEx is an international system for certification of equipment for use in potentially explosive atmospheres. Its quality assessment specifications are based on standards prepared by the International Electrotechnical Commission (IEC). Watlow will offer this improved level of safety through its energy and environmental technologies business unit.

Watlow has offered the Ex e certification on its process heaters for many years. The “eb” suffix as compared to the “e” suffix indicates the products meet the additional level of tests and safety in EN60079-7. The additional certifications offer a larger range of heater sizes and additional installation orientations.
