Electric Heating and Electrical Control Integrated System (Integrated Electric Heating and Electrical Control System) refers to the highly integrated combination of electric heating actuators (such as heating tubes, heating tapes, electromagnetic induction coils, etc.) with electrical control units (such as temperature controllers, PLCs, solid-state relays, sensors, protection circuits, etc.) to form a closed-loop controlled intelligent heating solution. This system is not just about "heating," but more importantly about "precise temperature control" and "safety monitoring." Below are its common application scenarios in industrial and commercial environments in 2026: 1. Plastic and Rubber Processing Industry (Most Typical Application) This is the most mature field for electric heating and electrical control integration, requiring extremely high temperature control accuracy (±1°C), which directly affects product quality. Injection Molding Machine/Extruder Barrel Heating: Scenario: Plastic pellets are melted in the screw barrel. Integration Features: Cast aluminum/cast copper heaters are embedded in the barrel, combined with multi-zone PID temperature controllers and thermocouples. The system automatically adjusts power based on screw speed and back pressure to prevent material degradation or poor plasticization. Hot Runner Systems: Scenario: Heating of the runner inside the mold to prevent plastic solidification. Integration Features: Use of valve-gate nozzles and dedicated temperature control boxes to achieve multi-point independent temperature control, ensuring stable injection cycles. Flat Vulcanizing Press/Calender: Scenario: Vulcanization molding of rubber products. Integration Features: Large-area flat plate heating requires uniform plate surface temperature, typically equipped with multi-point temperature measurement feedback systems. 2. Petrochemical and Energy Industry This scenario demands high explosion-proof safety and corrosion resistance, often involving hazardous areas (Zone 1/Zone 2). Pipeline Trace Heating: Scenario: Pipelines transporting crude oil, heavy oil, asphalt, or chemical liquids to prevent the medium from solidifying or increasing viscosity at low temperatures. Integration Features: Use of self-regulating electric heat tracing or constant power heat tracing, equipped with explosion-proof temperature control boxes and remote monitoring systems (DCS/SCADA), real-time monitoring of pipeline temperature and current, with leakage alarm function. Tank Heating: Scenario: Heating of the bottom or side walls of large oil storage tanks and chemical storage tanks. Integration Features: Insertion flange heaters or external heating panels, integrated with liquid level interlock protection (automatic power-off at low liquid level to prevent dry heating). Natural Gas Decompression Station Heating: Scenario: High-pressure natural gas decompression causes a Joule-Thomson effect leading to a sharp temperature drop, requiring preheating to prevent freezing and blockage. Integration Features: Explosion-proof pipeline heaters with fast response and high pressure resistance. 3. New Energy and Battery Manufacturing (Emerging Hotspot) With the development of electric vehicles and energy storage, temperature control during battery production is critical. Lithium Battery Electrode Drying: Scenario: Coated electrodes need to enter an oven to remove solvents. Integration Features: Hot air circulation heating system requiring extremely high temperature uniformity (within ±2°C) to prevent electrode cracking or solvent residue, typically using infrared heating or high-power duct heaters. Battery Pack Thermal Management System Testing: Scenario: Simulating heating performance of battery packs under extreme environments. Integration Features: High-precision programmable heating system capable of simulating complex heating curves. Electrolyte Heating: Scenario: Electrolyte viscosity increases at low temperatures, requiring heating to ensure filling efficiency. Integration Features: Corrosion-resistant (fluoroplastic heating tubes) and explosion-proof integrated heating modules. 4. Food and Pharmaceutical Industries This scenario has strict requirements for hygiene levels (GMP standards), materials (food-grade stainless steel), and temperature control accuracy. Reactor/Fermenter Heating: Scenario: Drug synthesis, biological fermentation, food additive production. Integration Features: Jacket heating or built-in coil heating, using 316L stainless steel material with polished surface, no dead corners, easy to clean. Control system requires data recording function (compliant with FDA 21 CFR Part 11). Sterilization and Pasteurization: Scenario: Instant high-temperature sterilization of milk, beverages, sauces. Integration Features: In-line pipeline heater with flow and power linkage control to ensure every drop of material reaches sterilization temperature without scorching. Packaging Heat Shrink: Scenario: Heat shrinking of product outer packaging film. Integration Features: Hot air gun or heating tunnel with temperature automatically adjusted according to conveyor belt speed. 5. Semiconductor and Electronics Manufacturing Wafer Fabrication Equipment: Scenario: Heating of process chambers in diffusion furnaces, CVD/PVD equipment. Integration Features: Ultra-high purity heating elements (such as quartz, special alloys) with temperature control accuracy of ±0.1°C, multi-zone independent control to compensate for edge heat loss. PCB Board Curing/Reflow Soldering: Scenario: Melting of solder paste, curing of adhesives. Integration Features: Zoned heating tunnel with precise temperature profile control. 6. Civil and Commercial HVAC Electric Boilers/Heat Pump Auxiliary Heating: Scenario: Northern "coal-to-electricity" heating, hotel hot water systems. Integration Features: High-power water-electricity separation heaters, integrated with flow switches, over-temperature protection, variable frequency control, achieving on-demand heating, energy-saving and efficient. Air Curtains/Fan Heaters: Scenario: Winter heating at shopping mall entrances, factory workshops. Integration Features: PTC ceramic heating elements (self-limiting temperature, safe), combined with fan linkage control.
