Member of the NIBE GroupSAN heating element type RV can be delivered withmounted stainless steel ribs. This increases the surfacearea of the heating element considerably, which means amuch lower surface temperature.HEATING ELEMENTSWITH RIBSThe specific load is calculated based on the followingformula:P =P(W/cm 2 )L b x 0,267P = power in kWL b = heating zone of the heating element in cm.The surface temperature of the heating element is particularlyimportant in connection with air heating in ducts andin Ex-equipment. The relation between air velocity (m/s),temperature difference (∆t) and surface load (W/cm²) isshown on the graph.The following physical manufacturing limitations havebeen stated:d a : 8.5 mmD a : 22.5 mm or 28 mmL: min. 420 mm, max. 5700 mmL R : min. 320 mm, max. 5600 mmMA : min. 35 mm or 40 mmTemperature difference ニt between maximum tubularjacket temperature and highest air temperature tLaThe temperature on the ribs,is constantly below the temperatureof the tubular jacket,and varies a lot depending onthe height of the air velocity.Specific surface load n W/cm2at a tube diameter of 8,5 mmL u : 50 mmL 1 : min. 45 mmAir velocity W in m/sGillelejevej 30 - DK-3230 Graested - DenmarkTel.: +45 48 39 88 88 - Fax: +45 48 39 88 98 - san@san-as.com - www.san-as.comCVR No.: 42 16 59 13 - A/S reg.

Member of the NIBE GroupThe SAN ceramic heating elements are manufactured to specificationand are used especially for designs where an easy dismountingof the entire plant or part of it is needed, and at thesame time emptying of tanks, pressure vessels and others areto be avoided.The SAN round ceramic heating elements are available in variousdiametres and lengths and are mounted mostly in tubewells in the plants, which are to be heated.CERAMICHEATING ELEMENTSROUND and FLATThe SAN flat ceramic heating elements are also available in variouswidths and lengths and are most often used for surfaceheating in order to obtain an even heat distribution.headround steatiteend discApart from that, the SAN ceramic heating elements are alsoadvantagely used in many constructions, e.g. furnaces in whicha high operating temperature up to 900。C is required.The below table can be used for most heating tasks.L KL VL = n 50LOAD TABLEflat steatiteAIR OIL WATER(stationary) (stationary) andcirculating1.5 W/cm 2 2 W/cm 2 OIL 3 W/cm 2Diametremm W per m W per m W per m10 475 650 95015 700 950 140017 800 1100 160022 1050 1400 210026 1250 1650 245029 1400 1800 270032 1500 2000 300036 1700 2250 340040 1900 2500 380045 2150 2850 425058 2750 3650 5500L KL = n 100L VWidth mmFlat ceramic heating elements48 725 950 145054 800 1100 162558 875 1175 1750Ceramic heating elements built in tubes onflanges for tank heating.REMEMBER VOLT and WATT - DIAMETER - TOTALwhen ordering: LENGTH (L) - COLD END(L k ) -CONNECTION TYPE.VERTICAL OR HORIZONTAL MOUNTINGGillelejevej 30 - DK-3230 Graested - DenmarkTel.: +45 48 39 88 88 - Fax: +45 48 39 88 98 - san@san-as.com - www.san-as.comCVR No.: 42 16 59 13 - A/S reg.

Member of the NIBE GroupSURFACELOADThe lifetime of a tubular heating element is mainly determinedby the operating temperature of the resistance wire. The temperatureof the resistance wire is directly dependant of the surfaceload (Watt per cm 2 ) of the tubular heating element.Stationary airThe graph fig. 1 shows the surface temperature of the tubularheating elements in various medias. The stated values areapproximate values, dependant of flow and pressure.OilAir at 10m/sWaterFIG. 1W/cm 2The graph fig. 2 shows the approximate temperature of tubularheating elements mounted in air stream as function of the velocityat constant surface loads.The ambient temperature is 20。C.Additional temperature graphs on page 27.FIG. 2m/sec.In the scheme fig. 3 a guiding load of tubular heatingelements used in various medias is stated.In medias with high heat transmission, the surface load can beincreased considerably in relation to load in air.In corrossive medias, where special tubular jacket material isrequired, the tubular heating elements can be supplied in acidproof steel, Monel 400, Incoloy 800, Inconel 600 and Titaniumas well as PTFE-coated. Also quartz tubular heating elementsare available.In medias, where special care should be taken against danger offire, Ex-danger and others, the surface load must be particularlylow.Our sales department is at your service as regards dimensioningof your special electrical heating assignment.Temp.
