Armored Electric Heater
Darui Electric recommends
Air Heater is an electric heating device mainly used to heat gas flow. The heating element of the air heater is a stainless steel electric heating tube. The inner cavity of the heater is equipped with multiple baffles (guide plates) to guide the gas flow, prolong the residence time of the gas in the cavity, thereby fully heating the gas, making the gas heating uniform, and improving heat exchange efficiency.Fan Air Electric Heater's heating elementStainless Steel Heating Tube is made by inserting electric heating wire into a seamless steel tube, filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, and then shrinking the tube. When current passes through the high-temperature resistance wire, the heat generated diffuses through the crystalline magnesium oxide powder to the surface of the heating tube, and then transfers to the heated gas to achieve heating.
Working Principle of Air Heater:
High-temperature resistance wires are evenly distributed inside a high-temperature resistant stainless steel seamless tube, and the gaps are densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation. This structure is not only advanced and has high thermal efficiency, but also heats evenly. When current passes through the high-temperature resistance wire, the heat generated diffuses through the crystalline magnesium oxide powder to the surface of the metal tube, and then transfers to the heated part or air gas to achieve heating.
FanAir Electric Heater is mainly used to heat the required gas flow from the initial temperature to the required gas temperature. It is particularly suitable for automatic temperature control and large flow high-temperature combined systems and accessory tests. The air heater has a wide range of applications: it can heat any gas, and the hot gas produced is dry, non-conductive, non-flammable, non-explosive, non-corrosive, stable and reliable, and the heated space heats up quickly (controllable).
Technical Features of Air Heater:
1. Can heat gas to very high temperatures.
2. High efficiency.
3. Fast heating rate, up to 10°C/s, fast and stable adjustment. No lead or lag in controlled gas temperature, preventing temperature control drift, suitable for automatic control.
4. Good mechanical performance: because the heating element is made of alloy material, it has better mechanical performance and strength than any other heating element under the impact of high-pressure gas flow, which is more advantageous for systems and accessory tests that require continuous heating of gas for a long time.
5. Durable when used in accordance with operating procedures.
6. Clean gas, small volume.
Common Faults and Maintenance of Air Heater:
Fault 1: Digital display not working. Check if the air switch is closed and the control circuit is intact.
Fault 2: Heater temperature not rising. Check if the fuse is intact,Gas Heater is damaged?
Fault 3: Three-phase imbalance. Check if the three-phase incoming voltage is missing a phase. Open the gas heater protective cover and use a multimeter to check if a single heating element is open circuit.
For faults that cannot be resolved by yourself, please consult a skilled technician (or contact our company's customer service).
