Catalogue Tubular Heating Elements Heating elements are often produced to customer-specific requirements. Sealing The heating element is sealed to prevent the magnesium oxide from absorbing moisture and thereby causing a transition point in the heating element. Two types of sealant are used, depending on how high temperature the seal may be subject to. • silicone: max. 180°C • polyurethane: max. 120°C Heating elements are used for applications such as ovens, cookers and griddles and for warming up tools and machinery. These heating elements are very flexible and can be bent to suit the...

Catalogue Tubular Heating Elements applications Of course, when choosing a tube cap material, the medium to be heated has a significant part to play. The surface load, W/cm², is another factor. If the surface load is too high, the heating element will overheat and burn. In the case of certain medium where the heat transmission is particularly high, a significantly higher surface load than in air can be accepted, just as the media may make specific demands of the tube cap material on account of corrosion problems. Likewise the media may demand a particularly low surface temperature due to...

Catalogue Tubular Heating Elements STAINLESS STEEL TUBING, AISI 304 All standard tubes of Ø8.5mm and Ø10.2mm come with M4 threaded bolt. Standard tubes of Ø6.25mm come with a Ø2.5mm pin (flat). It is possible to weld a spade or wire onto a flat pin. Type Ø8.5mm, AISI 304, cold zone 55 mm Item no. Surface load Type Ø6.25mm, AISI 304, cold zone 55 mm AISI 304 is used widely for duct heater in ventilation and air conditioning systems, for ovens, cookers and griddles, warming up tools and machinery, fan heaters and oil heater cartridges. AISI 304 is not suitable for water, and can be used only...

Catalogue Tubular Heating Elements STAINLESS STEEL TUBING, AISI 316L AISI 316L is used primarily for air heating in duct heater, particularly for offshore applications, oil installation and in other damp environments. To a limited extent, AISI 316L is also used with restrictions with some acids/bases and with aggressive gases. Type Ø8.5mm, AISI 316L, cold zone 90 mm Item no. Surface load CORROSION AND ACID RESISTANT TUBING, INCOLOY 825 Incoloy 825 is used wherever heating elements are required which are able to withstand aggressive media, but it can also be used for heating water which...

Catalogue Tubular Heating Elements DIMENSIONING Diagrams/curves are used to indicate the maximum permitted surface load (W/cm²) as a function of the operating/ ambient temperature. These curves act merely as a guideline as the heat passing between the elements will have a part to play. If the heating elements are used in a duct heater, the length of this will also have an influence. Example 2 (see the diagram below) What would the maximum permitted surface load be if we have an AISI 316 heating element and the following operating conditions are prevalent? • operating temperature of 350°C •...
