Self Regulating Heating Cable

Basic introduction: Electric heat tracing is an effective pipeline insulation and antifreeze solution, which has been widely used. Its working principle is to dissipate a certain amount of heat through a heat tracing medium, and supplement the loss of the heat tracing pipeline through direct or indirect heat exchange, in order to achieve the normal working requirements of heating, insulation or antifreeze. Electric heat tracing is a uniform heat release along the length of a pipeline or over a large area of the tank volume, which is different from electric heat tracing where the heat load is highly concentrated at a single point or over a small area; Electric heating has a small temperature gradient and a long thermal stability time, making it suitable for long-term use. Its required heat (electric power) is much lower than that of electric heating. Advantages: (1) The electric heat tracing device is simple, produces uniform heat, has accurate temperature control, and can be remotely controlled to achieve automated management. (2) Heat has explosion-proof, all-weather working performance, high reliability, and long service life. (3) Electric heat tracing has no leakage, which is beneficial for environmental protection. (4) Save steel: It does not require the one to two heat tracing pipelines required for steam tracing. (5) Save insulation materials. (6) Save water resources, unlike boilers that require a large amount of water every day. (7) Electric heat tracing can also solve the problem that steam and hot water heat tracing are difficult to solve. (8) Electric heat tracing design has a small workload, easy and simple construction, and low maintenance workload. (9) High efficiency, can greatly reduce energy consumption. Summary: Electric heat tracing is the only new generation strip constant temperature electric heater that can automatically limit the temperature during heating and adjust the output power according to the temperature of the heated object without any additional equipment; It can be cut short or extended within a certain length range, suitable for temperature control, heat tracing, insulation, and heating of pipelines, equipment, and containers, especially when materials are prone to decomposition, deterioration, crystallization, condensation, and freezing. It has a wide range of applications in the production and processing of petroleum, chemical, power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline products, and other sectors. It is a technological development direction that replaces steam and hot water tracing.

The heating cable heating system is not limited by environmental conditions and can be installed in any place with heating needs. It can be installed on the ground, walls, or ceilings, providing room heating, antifreeze insulation for pipelines, and melting snow and ice on outdoor roads and roofs. Especially for larger spaces such as clubs, exhibition halls, cinemas, sports halls, etc., the heat transfer distance of wall mounted radiators is limited, making it difficult to meet the heating requirements of the entire indoor space. In addition, the indoor heat distribution is uneven, and the ground radiation heating method of heating cables uses the entire ground as a radiator, resulting in uniform indoor temperature distribution. At any position in the room, there will be a warm and comfortable feeling. For large space buildings with glass curtain wall structures, since radiators cannot be installed on the wall, it is more suitable to install heating cable heating systems.

 Ground radiation heating system (most mainstream application)   1. Application scenarios Residential/apartment: Replace traditional water heating and achieve independent heating for each household (such as using dual conductor heating cables and intelligent temperature controllers in the community, with room temperature controlled at 20 ± 1 ℃). Villa/clubhouse: With different floor materials such as marble and wooden flooring, comfortable heating is provided through low-temperature radiation (surface temperature ≤ 28 ℃). School/Office Building: Large space areas such as classrooms and conference rooms that can be temperature controlled in zones (for example, a certain office building uses carbon fiber heating cables, which consume 25% less energy in winter than central air conditioning). 2. Technical points Cable selection: Single conductor/double conductor heating cable: Double conductor (without electromagnetic interference) is preferred for home decoration, with a power density of 10~15W/㎡; Carbon fiber cable: suitable for wooden flooring (with good heat uniformity to avoid local overheating). Temperature control configuration: 1 programmable temperature controller is provided every 15-20 square meters, supporting temperature control in different time periods.   Pipeline and equipment anti freezing and insulation   1. Application scenarios Water supply and drainage pipelines: Exposed water pipes in residential areas (such as balconies and kitchens) are equipped with self limiting heating cables to maintain a water temperature of ≥ 5 ℃ and prevent frost cracking. Water heater/wall mounted boiler: The water tank and inlet and outlet pipes are heated to ensure normal start-up in low-temperature environments. Central air conditioning duct: In winter, prevent condensation water from freezing and maintain a temperature of ≥ 10 ℃ inside the duct. 2. Technical points Cable type: self limiting temperature heating cable (power automatically decreases with temperature increase), heat tracing temperature ≤ 60 ℃; Temperature controller: equipped with a temperature sensor, automatically starts below 5 ℃ and stops above 15 ℃.   Toilet Comfort Application   1. Application scenarios Ground heating: Install heating cables in the shower area to avoid barefoot contact with cold ground. Towel rack/mirror anti fog: Carbon fiber heating cable embedded in towel rack (power 50-100W), with both drying and heating functions; Mirror backed film heating cable to prevent fogging during showering. Floor heating+dehumidification linkage: The bathroom temperature controller integrates a humidity sensor, which automatically starts heating and dehumidification when the humidity is above 70% (more commonly used in humid areas). 2. Safety design The cable needs to pass IP67 waterproof certification, and the joint should be sealed with hot melt adhesive; The temperature controller adopts a splash proof panel, and the leakage protection action time is less than 0.1 seconds.   Snow and ice melting system (outdoor scene)   1. Application scenarios Entrance steps/ramps: A constant power heating cable is pre embedded under the marble or concrete steps, which automatically starts in case of snowfall (a villa case: clearing 5cm thick snow within 5 minutes). Roof/gutter: To prevent the eaves from falling due to snow and ice accumulation, cables are laid along the drainage channel (with a power of 20~30W/m), and temperature controllers are linked with rain and snow sensors. Garage entrance and exit: The heating cable is combined with anti slip floor tiles, and automatically heats up below -10 ℃ to avoid vehicle slippage. 2. Power supply plan Adopting 380V three-phase power supply (for long-distance installation), with a single circuit length of ≤ 100m, to avoid voltage attenuation.   Special function area heating   1. Application scenarios Thermal insulation of bay window/french window: lay heating cable under the sill plate to reduce cold radiation). Moisture proof storage room: The basement storage room is heated on the ground to maintain a temperature of 15-18 ℃ and a humidity of ≤ 50% (suitable for storing red wine, tea, etc.). Pet room/greenhouse: Low power cables (5-8W/㎡) are laid below the pet bed, and the temperature controller is set to maintain a constant temperature of 25 ℃; The balcony greenhouse is customized with temperature curves according to the needs of the plants (such as succulent plants at 28 ℃ during the day and 15 ℃ at night). 2. Energy saving design Using intelligent temperature controller and human body sensor, the temperature will automatically decrease by 5 ℃ within 30 minutes after the person leaves.   Combined application with renewable energy   1. Integrated solar thermal storage system Paired with solar photovoltaic panels, utilizing low electricity prices at night for heating. Energy storage batteries are prioritized for supplying heating cables, achieving "spontaneous self use, surplus electricity heating". 2. Air source heat pump linkage In low-temperature environments (<-5 ℃), when the efficiency of the heat pump decreases, the heating cable automatically replenishes heat.   Through the above applications, heating cables have achieved an upgrade from basic heating to scenario based comfort solutions in civil buildings, especially in cold and "wet cold" areas, where their energy-saving and comfort advantages are more significant.
