Maltec-H ATEX/IECEx certified flange heaters are designed for the heating of non-hazardous fluids (water, oil, heavy fuel, glycol, acids, caustic soda, asphalt, etc.) or gases (air, nitrogen, oxygen, CO2, etc.) by natural or forced convection up to 1500 kW, 750 V 3-ph, 400 °C, 50 bar. ATEX certified according to Directive 2014/34/EU or IECEx, for installation in an explosive atmosphere (risk zone 1 and 2) and for a temperature class from T1 to T6.

The heating elements are welded onto a flange conforming to standard EN1092-1 or ASME B16.5, with dimensions from DN125 (5”) to DN500 (20”). An electrical control and power supply unit with protection mode “e”, “d” or “de”, in painted steel, cast iron, aluminium or stainless steel, protects the connections from the heating elements to the power supply and from the control and safety devices to the power cabinet. Maltec-H flange heaters are designed and manufactured as part of our standard range or as a customised solution for installation on vessels conforming to European directive 2014/68/EU (PED).
