The high efficiency line can reduce the leather shrinkage rate by 5%-10%, meanwhile save the energy more than 50% Compared with electric drying system. High radiation efficiency：Heat is transferred to the leather by radiation rapidly and easily. Homogeneous combustion：The combustion is homogeneous along the width, ensure drying leather evenly. Good flashback resistance: special structure for full-premixed burner avoids flame flash-back. Low thermal inertia: burner surface temperature can drop down to room temperature in several seconds while the system stopped, which makes it can effectively prevent fire accidents caused by power break. Adopt built-up structure, easy to assemble and maintenance.Multi-angle stainless reflector: reflect infrared ray back to the leather surface. Covered by heat insulator: low thermal conductivity, low temperature on outside surface and low thermal loss.
