AIR PREHEATER MOSTLY IS USED FOR OIL HEATER BACK SIDE .THE HOT  DUST SMOKE OUT OF OIL HETER BODY, THEN GO INTO THIS AIR PREHEATER , SMOKE TEMPERATURE WILL BE DEDUCED AND NORMAL AIR WILL GO INTO THIS AIR PREHEATER FROM ANOTHER SIDE, DUE TO HEAT EACHANGING, AIR WILL BE HEATED  BECOMING HOT AIR AND COME OUT FROM AIR PREHEATER ,THEN TRANSFER INTO OIL HEATER BODY BY DRAFT FAN TO SAVING FUEL ,THIS HOT AIR WILL BE BURNED QUICKLY AND HEAT THE OIL HEATER QUICKLY. ANOTHER SIDE, AFTER THROUGH THIS AIR PREHEATER SMOKE TEMPERATURE WILL BE REDUCED AND THEN USE OTHER DEVICE TO REMOVE ITS DUST AND OTHERS .
AIR PREHEATER CAN SAVE FUEL ABOUT 5-10%,SO IT IS WELCOMED BY ALL USERS OF OIL HEATER.Advantage: Using column tube type structure, surface enamel technology. Contact with the flue gas of enamel surface, can effectively prevent the dew point corrosion. Lowest temperature of flue gas side can meet the working condition of 60 degrees, the corrosion life is long,Enamel tube surface is smooth, not easy to dust, enamel surface can avoid low temperature dew point corrosion.
