100 -12 Cover 093 — Immersion Heaters ROTKAPPE® ROTKAPPE Immersion Heaters are most suitable for direct heating of nearly all process liquids and cor-responding applications. Excellent chemical resistance is ensured by the use of different immersion tube materials and variable fitting options help you to meet the individual requirements of heating installations. A long life span with optimum reliability is assured by using high quality materials thereby ensuring faultless operation of your system. The ROTKAPPE immersion heater is constructed on a modular basis and consists of a tube, a long-life heating cartridge, a terminal casing and the lead. The Immersion Heater Tube We can offer you the optimum material for every application. The heated length (minimum immersion depth) is marked by a ring which is generally two-thirds of the tube length. The tube is not heated above this mark. The heated portion must always be covered with liquid even in the case of high liquid level fluctuation. The Long-Life Heating Cartridge Long-life heating cartridges are made from ceramic groove bodies with high electrical insulation values and good mechanical strength. A high temperature resistance heat-ing wire is fitted as a coil in order to achieve the best possible heat radiation from tube to liquid. The cartridges for immersion heaters are available in rated power voltages up to a maximum of 500 volts for one, two and three phase connections. The Terminal Casing BC The BC terminal casing for immersion heaters consists of high temperature stabilized PP. Problem-free use in most process liquids is ensured by good mechanical and thermal strength as well as wide ranging chemical resistance. The PVDF terminal casing (BC/L) is recommended in cases of extreme temperature (liquid temperature >80°C) or when subjected to strongly oxidizing chemicals (e.g. chrome electrolyte or HNO3). The protective casing is IP 65 (jet-waterproof) according to EN 60529. Easy access to the terminal (after fitting) when connecting the lead is also ensured by unscrewing the cap with the mounting wrench SB. The Lead The PVC connecting lead is with a standard length of 1.6m. Other lead lengths can be provided if desired. o £ E E I 1 Diameter Immersion Heater ROTKAPPE Electrical Safety The immersion heaters are classified as "safety class 1" according to EN 60519 /1-2. All metal parts that are not protected from human contact are securely connected to earth. Using non-conductive tubes made of porcelain or glass, a "protective coil" is also fitted to the heating cartridges in order to earth these tubes. The highest possible elec-trical safety is therefore ensured by using an earth leakage circuit breaker (ELCB). ROTKAPPE immersion heaters type B-... carry the VDE label.
