Oil heating drying kiln
 

We designed the new type of heat conducting heater of oil and electricity.The study is particularly convenient for small and medium wood processing enterprise. There is no need to use boiler,heat conduction oil replaced the traditional steam or high temperature water.The oil can be heated soon, the heat can be kept for a long time, and will deliver the heat to the interior of the surrounding space, cut off the power still be kept for a long time. Because of the high temperature of heating oil and high thermal conductivity, the capacity of the heater is smaller than the boiler. Heater can be installed directly in the control room of the drying kiln,no need to set up a separate boiler room. Heater can be shipped to the final destination, and installed together with the kiln, it can make save time and reduce the installation cost. Users should consider of local power and electricity costs
