8 Model Z.71 flange immersion heaters Use In case the application requires high power we may supply flange immersion heaters This kind of heaters may be customized or designed by our technical dep. depending on customer s needs. We design the flange immersion heaters depending on liquid features, working temperature, working environment, application,plug dimension. Useful hints for the design. l iquid.: in case of un unusual liquid please, let us know the following features: Specific weight (Kg/dm 3 ) Specific heat (Kcal/Kg C) Viscosity (cp) l iquid quantity [min/max] (l) l Container dimension (mm) l Container volume (m3) l Max working pressure l T1 ( C) l T2 ( C) l Time to reach the working temperature l Installation: vertical/horizontal (if vertical please lay them with liquid minimum level over the unheated part) l Flange UNI or ANSI lfeedings (voltage and if single phase or three phase) l Electric connection index protection ( IP 00 / 40 / 55 / 65 ) l Power ( se già definita ) (kw) Beware: please, indicate any further details For further information please contact our technical dept. We reserve the right to change technical details. Please follow the installation and storage instruction (see page 11). 8

11 Installation and storage instruction Installation l Plug immersion heaters may be used both in vertical or horizontal position. Anyhow it is necessary to lay them with the heated part completely immersed. This kind of heater is normally connected by screwing in case the machinery has a coupling box with a matching thread-; however is also possible to connect it by a separate hole and fastened to it by a ring nut or grommet nut In the presence of gasket please verify their capacity to reach the max. working temperatu re/pressure the device will reach. If supplied with a thermostat please, connect it in order to interrupt the feedings and consequent ly the heating- when the set temperature is rea ched. After using the heater at the working temperature few hours please verify/check the tightening of the threaded parts. Store l Store at room temperature in a dry place. Operation l Security procedures for the the handling of electrical items and application must be followed Do not touch the heater while in use because it can get very hot Please make sure that the hea ting elements can not touch flammable material while in use. Temperature controllers l Temperature controllers have to match the power consumption and the used temperature. Electric connection Beware l Please, stick to the nameplate features (specially regarding feeding voltage and power). Please, use connection leads suitable for the environment in which they are used. lthis kind of heaters contains magnesium oxide an insu lating and highly hygroscopic material. That is why if laid in a damp environment a bit long, the humidity tend to accumulate / gather inside the heaters causing insulation resistance decreasing with consequent intervention of safety device. lin case of long term storage is expedient before to use the heaters to check the insulation resistance with an insulation tester applying it between the phase and the earth: while using a tension not less than 500V the revealed insulation resistance value has to be equal or superior to 5 Megaohm. In case the checked value is lower a drying up will be neces sary putting the heaters in a oven at a temperature between 100 and 130 C till the insulation value will be restored (nor mally about 10/12 hours). 11
