- Description
-
- Commodity name: Cold storage door and ground anti-freeze insulation system
Some food and raw materials in daily life and production are to be frozen, and large cold storage solves this problem, large cold storage warehouse is a kind of food, inventory of raw materials for low temperature frozen storage of giant equipment, this cold storage is 24 hours a day in the work of operation, the production of frozen refrigerators, in this continuous operation, the low temperature environment makes some original equipment such as pipes, valves, cold storage doors, etc. appear on the surface of frost, over time will freeze, there will be frozen pipes, the valve and the cold storage door cannot be opened.
► Application scenarios
Some food and raw materials in daily life and production are to be frozen, and large cold storage solves this problem, large cold storage warehouse is a kind of food, inventory of raw materials for low temperature frozen storage of giant equipment, this cold storage is 24 hours a day in the work of operation, the production of frozen refrigerators, in this continuous operation, the low temperature environment makes some original equipment such as pipes, valves, cold storage doors, etc. appear on the surface of frost, over time will freeze, there will be frozen pipes, the valve and the cold storage door cannot be opened.
In order to ensure the normal operation of the cold storage, ensure the preservation effect of the internal raw materials, eliminate the operation obstacles, and make the equipment system run stably, it is recommended to use the electric heat tracing system to heat and trace some important components, play the role of heating and ice melting, and solve the situation that the pipes, valves, and cold storage doors are frozen and cannot be used normally.
Application range of special heating tracing for cold storage:
Cold storage, freezer, quick-frozen cold storage, food cold storage, fresh-keeping cold storage, pharmaceutical cold storage, logistics cold storage, modified atmosphere storage.
Freezers require cooling pipes for electric defrosting, regular defrosting, and refrigerator doors are thawed, which need to be opened for a long time or instantly in order to make it easy to open and close. People who use old refrigerators know that the frost thickens after being used in the freezer for a long time. This is because there is a lot of moisture in the refrigerator, and it is a common phenomenon for frost to become cold. The same is true of freezers, where frost occurs and the frost thickens.
When the frost is thick in the cold storage, the refrigeration effect and the opening of the cold storage door are affected. Therefore, we need to regularly defrost the condenser tubes with a special heating trace for cold storage. The edge of the refrigerator door is made of thick rubber material, which makes it difficult to open after prolonged frost at low temperatures. There are often freezer-freezer doors, which are difficult to open, and long-term use will also damage the sealing rubber.
► Cold storage door and ground anti-freeze insulation system
The main components of the electric heating system: self-limiting electric heat tracing, power junction box, terminal junction box, thickened aluminum foil tape, heat-resistant pressure-sensitive tape, temperature sensor, stainless steel cable tie, etc.
System Advantages:
1. Cost-effective: The electric heat tracing designed and selected by our company has a long service life, low maintenance rate and high heat transfer rate.
The advantages of YATALO self-limiting electric heat tracing: low starting current, low upfront power distribution cost, long service life, low maintenance cost in the later stage, low power consumption for long-term operation, and high heat conversion rate. We pay attention to the quality of each single product and the professional quality of system integration products, so as to achieve the effect of reducing costs and increasing efficiency in the real sense.
2. Safety guarantee: The main performance items of YATALO electric heating product manufacturing standards meet the GB/T19835-2015 standard, and the product materials are made of high-quality materials to ensure that the performance of the electric heat tracing meets the standards, with good thermal stability, low starting current, uniform heating temperature, heating temperature is within the standard range, will not overheat or short circuit lead to heat tracing combustion or burning, long service life, low attenuation of power meter, and high cost of replacement cycle caused by short life.
(Installation diagram)► How it works
The temperature sensor installed in the cold storage door or the ground will be transmitted to the temperature control instrument through the signal cable, the temperature control meter will compare the temperature received with the set temperature, when the current temperature is greater than the set temperature, the electric heating will not work, when the current temperature is less than the set temperature, the electric heating will start to work, in order to avoid frequent starting, generally set a return difference, can also be connected with the central control room or DCS system by remote communication, and can be observed and controlled at the remote end to start and stop the electric heat tracing.
► Conventional selection
1. Tinned copper core wire
2. Conductive Plastics (Heat-Generating PTC)
3. Inner insulation layer (modified polyolefin/LSZH/fluorinated type)
4. Metal shielding layer (metal alloy wire/tinned copper wire)
5. Outer sheath layer (modified polyolefin/PVC/LSZH/fluorinated type)

Product hotspot: The advantages of self-limiting electric heat tracing: small starting current, low early power distribution cost, long service life, low maintenance cost in the later stage, low power consumption in long-term operation, and high heat conversion rate. ► Construction and installation
Installation specification steps: check whether the surface is polished smooth and free of burrs and sharp edges, dry and free of dirt; Check whether the corresponding heating tracing materials and accessories are consistent with the materials in the design table; Check whether the materials required for construction are in good condition, etc.
Key points of construction and installation: In the installation of electric heat tracing generally adopts the way of straight paving, during installation, every interval of 300-600mm is fixed with heat-resistant pressure-sensitive tape, after the installation is completed, along the direction of the electric heat tracing is covered with a layer of aluminum foil tape, which is used to increase the heating area of the pipeline, the power junction box and the temperature sensor are fixed on the track with stainless steel tape, and the two-way junction box and the three-way junction box are fixed with heat-resistant pressure-sensitive tape.
