Vacunair Engineering Co. Pvt. Ltd offers Furnace Oil Tank Suction Heater. Vacunair Engineering Co. Pvt. Ltd is an ISO 9001 certified company. This Furnace Oil Tank Suction Heater has viscosity of 1500 Sec Redwood No. 1 at 100 Deg F. 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. These 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, but only heats the oil that flows through the heater thus cutting down the kilowatt[KW] rating which otherwise may require to heat entire oil tank. The operation is smooth and safe. Range Capacity: 1 KW to 200 KW and Oil Flow: 10 to 3000 LPH.
