When 400cSt with built-in fan-in-one cast aluminum industrial burners, applicable to a fuel viscosity of 50 ° C (equivalent to a viscosity of 50) heavy oil at 50 ℃. This series of products using mechanical pressure atomization, with a dual heating unit, built-in power rating of electric heating components, to avoid carbon deposition and fuel to maintain the specific viscosity and flow state. The product uses natural gas or liquefied petroleum gas is independent of ignition. The main technical characteristics of this series of products, optimizing the combustion head and the structural relationship between the combustion tube, specially designed inducer give full play to the performance of the fan. Series of excellent Ni Wasi's burner, the series burner through multiple trials and testing, is safe and reliable, excellent quality and ideal products.
