HRY series sheathed tubular electric heater for hydraulic, lubrication apparatus for heating lubricating and hydraulic oils can also be used to heat non-corrosive gases or liquids. By the heating of the core and sheath components. Heating cores with high temperature alloy heating wire as a heat source for the high temperature ceramic dielectric ceramic cross, cold drawn seamless jacket or stainless steel. Electric heater and tank body flange connection. The core and the sheathed heating oil is heated isolation, the replacement of electric heaters, do not need to let go of the oil tank, just out of the heater core, replace it with a new heating core can be, easy to maintain electric heater with the heated fluid contact area, small surface power, does not produce carbon, oil is not locally high temperature carbonization. Long life, safe and reliable. HRY series sheathed tubular electric heater main technical parameters Rated voltage single phase 220V, three phase 380V surface heating power ≤3W / CM2 temperature ≤300 ℃ Working medium Working pressure ≤0.8Mpa mineral oil products Source: www.ybzhan.cn /st58509/product_8459887.html sheathed tubular electric heater Other Recommendations: www.ybzhan.cn/st58509/product_8446328.html automatic transformer integrated test instrument
