What are the characteristics of the nitrogen electric heater of the medium thermal machinery

A nitrogen heater is an electric heating device that mainly heats a gas stream. The heating element of the electric heater is a stainless steel electric heating tube, and the inner cavity of the heater is provided with a plurality of baffles (deflectors) to guide the gas flow direction and prolong the residence time of the gas in the inner cavity, so that the gas can be fully heated, the gas is heated evenly, and the heat exchange efficiency is improved. The stainless steel heating tube of the heating element of the air heater is made by filling the heating wire in the seamless steel pipe, and filling the void part with magnesium oxide powder with good thermal conductivity and insulation.

When the current passes through the high-temperature resistance wire, the heat generated spreads to the surface of the heating tube through the crystalline magnesium oxide powder, and then transmits to the heated air to achieve the purpose of heating.

A nitrogen heater is an electric heating device that is used to heat gas by installing a heating pipe in a cylindrical insulated container. The nitrogen heater has the characteristics of fast heating speed, good thermal insulation performance and high heating temperature. Nitrogen heaters are usually used to heat air, nitrogen and other gases, and can heat the gas to the desired temperature in a very short time.

The specific size and heating time are customized according to customer needs.

We have always been energy saving, environmental protection for the design and development of the concept of products, on the basis of the continuation of their own technology, and constantly introduce the world's advanced technology and management experience, and constantly improve the production technology, improve product quality - medium heat machinery.

Jiangsu Zhonghe's - every product always adheres to ingenuity. With a history of more than 10 years in the manufacturing field, the product quality is a silent salesman in the middle heat, and the quality is consistent!

The concept of manufacturing, intelligent manufacturing, and quality manufacturing 2025.

Tianhe parking heater has a good reputation in the industry, produced by large manufacturers, trustworthy, with a factory area of 60,000 square meters, and after-sales is guaranteed.

1. The electric heating pipe adopts corrugated stainless steel strip winding outside, which increases the heat dissipation area and greatly improves the heat exchange efficiency.

2. The design of the heater is reasonable, the wind resistance is small, the heating is uniform, and there is no dead angle of high and low temperature.

3. Double protection, good safety performance. Thermostats and fuses are installed on the heater, which can be used to control the air temperature of the air duct and work without wind to ensure that nothing goes wrong.

Technical characteristics of ducted air electric heater.

1. It can make the air heated to a very high temperature, up to 450, and the shell temperature is only about 50.

2. High efficiency: up to above.

3. The heating and cooling rate block can reach 10 s, and the adjustment is fast and stable. There will be no temperature drift due to the temperature of the controlled air temperature leading and hysteresis, which is very suitable for automatic control.

4. Good mechanical properties: because its heating element is a special alloy material, it has better mechanical properties and strength than any heating element under the impact of high-pressure air flow, which is more advantageous for system and accessory tests that require long-term continuous heating of air.

5. When it does not violate the rules of use, it is durable and has a service life of up to several decades.

6. Clean air and small size.

The nitrogen electric heater has reasonable structure, complete supporting facilities, short installation period, simple operation, high degree of automation, and a wide range of safety and hail rubber applications.

With advanced operation control and safety monitoring devices and oranges, it can accurately provide process temperature for the heating equipment and automatically adjust the load next to the heat source shed through the set temperature feedback to the control system. The closed-circuit circulating heating is adopted, the heat loss is small, the energy saving effect is remarkable, and it can meet the needs of different multiple heating equipment. Low operating costs and fast investment.

The nitrogen-electric heater adopts intelligent automatic control, automatic temperature display, constant temperature protection, and over-temperature alarm. The heating temperature is controlled at 3 to ensure that the unit fully meets the user's requirements. And it has advanced multiple protection and reliable monitoring devices.

a. There are conventional electrical protection, such as short circuit protection, etc.

b. Monitor the process temperature and bring alarm output.

c. The control algorithm adopts fuzzy control theory, and the PID parameter setting can be completed automatically.

d. There is a set of over-temperature alarm system independent of temperature control, when the heater exceeds the set value, it will turn off the electric heater without automatic reset, and output a contact signal.

e. Several interlocking interfaces can be provided to interlock with other equipment (such as fans) to ensure that there is a certain flow of medium flowing when the heater is heating to ensure the safety of the system.
