Valseshika electron manufactures furnace oil tank suction heater. Furnace oil has viscosity of 1500 sec redwood no: 1 at 100°f and with a fall in temperature this viscosity goes further up making oil to flow extremely difficult. To meet this demand tank suction heaters have been designed. The furnace oil tank suction heaters are installed at little above the tank bottom. The beauty of the heater is that it does not heat entire tank filled with oil - it only heats the oil that flows through the heater thus cutting down the kilowatt ratting which otherwise may require to heat entire oil tank. The operation is smooth and safe. The range - 1 kw to 130 kw.
