The CNF (Z) steam series heater consists of a heat sink coil, an impeller, a Wind circle, and a motor. Heat pipe, the heat dissipating fin adopts a mechanical winding method, which is wound around the heat pipe (can also be used as needed). The heat radiating fins and the heat pipe have a wide and tight contact surface, thereby improving heat transfer performance and working pressure, and the heating medium is generally 0.3MPa saturated steam, the highest saturated steam working pressure is 1.0 MPa, the impeller adopts LF3 anti-rust aluminum, the casing is welded by ordinary steel plate or stainless steel plate.
