Section II: Overview of 200KW Vertical Air Electric Heater

Air electric heaters are primarily used to heat the required air flow from an initial temperature to the desired air temperature. They have been widely applied in aerospace, weaponry industry, chemical industry, and many scientific research and production laboratories in colleges and universities. Particularly suitable for automatic temperature control and high-flow high-temperature combined systems and component testing. Air electric heaters have a wide range of applications: they can heat any gas, produce dry hot air without moisture, non-conductive, non-flammable, non-explosive, non-corrosive, non-polluting, safe and reliable, and the heated space warms up quickly (可控).

IV. Overview of 200KW Vertical Air Electric Heating Element Control System:

Overview of Intelligent Full-Automatic Control System:

The electric heating intelligent fully automatic control cabinet is a dedicated temperature control device designed for our company's various electric heating equipment to form an electric heating system. It integrates main circuit protection, temperature measurement and control, as well as flow, pressure, working current, voltage, and system pump controls into a single unit combination device.

The temperature control system in an electric heating system is an essential component.

2. Conditions for Using the Intelligent Fully Automatic Control System:

Ambient Temperature: -15℃ to 40℃

Relative Air Humidity: ≤95%

(3) Installation Location: Non-explosion-proof areas, non-corrosive, indoor installation

(4) Protection Level: IP55 (Outdoor), IP23 (Indoor)

(5) Altitude: Above Sea Level

(6) Power Supply: 400-230V 50Hz

3. Features of the intelligent fully automatic control system structure:

Control cabinets are available in two types: suspended and floor-standing. Floor-standing cabinets can be customized with front doors or double doors as per customer requirements. Control cabinets can be categorized as outdoor or indoor based on the installation location. One cabinet can be assembled with multiple control units, allowing for the measurement and control of multiple sets of electric heating equipment.

4. Features of the Intelligent Automatic Control System:

(1) The main circuit of the electrical control cabinet is protected against short circuits, overloads, and disconnection of heating elements by an automatic air switch.

(2) The electrical cabinet can be electrically interlocked with related level controllers or oil pump control devices.

(3) A separate over-temperature alarm system independent of the temperature control, which will shut down the electric heater automatically without reset when the internal temperature exceeds the set value, and output a contact signal.

(4) We offer several interlock interfaces with the DCS (analog, digital).

(5) Features manual/automatic seamless switching capability.

(6) Achieve full automatic monitoring.

5. Working Principle of the Intelligent Fully Automatic Control System:

Advanced technologies in comprehensive disciplines such as heat transfer, chemical engineering, thermodynamics, thermal structure engineering, electrical engineering, instruments, automatic control, mechanical engineering, and software and hardware engineering of computers are the result of our company's long-term commitment to the development and research in the field of electric heating equipment, guided by practical experience in the detection, control, optimization, and amplification of electric heating processes. The product features include:

Can simultaneously detect and control the heating temperature, pressure*, and medium flow* of the medium.

Equipped with automatic control for key parameters such as temperature, pressure, and motor soft start-up.

Equipped with temperature detection*, pressure detection*, flow detection*, current, voltage detection*, medium liquid level height*, insulation resistance detection*.

Can be set for upper and lower limits of temperature, pressure*, and flow*, and equipped with an alarm function for over-limit conditions.

All alarm incidents can be recorded and reviewed.

Equipped with over-temperature, low flow, three-phase unbalanced resistance, leakage, and automatic shutdown alarm functions.

Temperature, pressure, current, voltage, flow rate, etc., can all be set to automatic, manual, or off states.

Parameters such as medium temperature, pressure, current, and voltage can be automatically tracked and controlled according to the set curve.

Each parameter features a PID adjustment process display, including set values, real-time values, PID set values, upper and lower limit values, curve tracking display, manual/automatic switching, and online settings; all set parameters can be restored to their original state after a power outage and subsequent restart.

Historical data and curves for various parameters can be saved for years (requires a supervisory computer to function); key parameters are synchronized to the database for immediate data analysis.

User-friendly interface with the ability to switch between ten different monitoring screens.

The system features various interrelated controls: temperature and power interrelation control, system pump and flow interrelation control, and current, voltage, and electric heater interrelation control, among others; it also offers real-time display of the operational process, data recording, data analysis (bar graphs, line charts, and batch reports), output printing, password management, abnormality analysis, and alarm functions. The interface is fully in Chinese with detailed help instructions. The recording screen can simultaneously display up to 8 different curves in various colors, and more curves can be sequentially displayed if needed.

Remote monitoring of the electric heater's operating status is available via local area network or the internet.*

Parameters of each detection and control loop can be set and adjusted manually online on the screen, including calibration of temperature, power, and temperature sensors, as well as calibration of pump flow rates. The operation features multi-level password protection and assigns different operational permissions.

Automatically records the power-on time, power-off time, number of power outages during automatic operation, outage duration, and power restoration time for electric heaters.

The software system features adaptive and self-diagnostic capabilities; abnormal situations can be automatically reported and protective actions initiated based on customer settings.

Large LED displays with critical parameters at the site*; display temperature and pressure—clear, critical parameters at a glance.

Note: The above is a basic description of the functions, which can meet the requirements of most electric heating processes. Functions marked with an asterisk (*) are expandable options for the user to choose from.
