1. The air can be heated to a very high temperature, up to 450 ° C, the shell temperature is only about 50 ° C.
2. High efficiency: up to 0.9 or more.
3. Heating and cooling rate block, up to 10 ° C / S, fast and stable adjustment. There is no leading air temperature lead and hysteresis, which makes the temperature control drift, which is suitable for automatic control.
4. Good mechanical properties: because its heating element is a special alloy material, so under the impact of high-pressure air flow, it is better than any heating body mechanical properties and strength, which is necessary for a long time continuous air heating System and accessory testing is even more advantageous.
5. It is durable and has a service life of several decades without violating the use rules.
6. The air is clean, small size.
