- Description
-
- Commodity name: Tanks, pumps and valves anti-freeze tracing system
In winter, the ambient temperature drops, the tank or tank due to the large surface area, the heat loss is large, the need for moderate anti-freezing or even insulation, so as to avoid the storage of the medium due to the temperature drop caused by freezing, viscosity change, crystallization, etc., and even due to the change of specific gravity and the formation of stratified separation phenomenon. No matter the horizontal or vertical round tank, or the square tank, it can be used for heat tracing and heat preservation or temperature maintenance.
► Application scenarios
When the ambient temperature drops in winter, the tank or tank body needs to be moderately anti-freezing or even heat preservation due to the large surface area and large heat loss, so as to avoid the freezing of the stored medium due to the temperature drop, viscosity change, crystallization, etc., and even the formation of stratified separation due to the change of specific gravity. Whether it is a horizontal or vertical round tank, or a square tank, it can be used for heat tracing insulation or temperature maintenance by electric heat tracing.
Typical applications include: cooling tower heat insulation, reaction tower heat maintenance and temperature maintenance, chemical storage tank heat tracing and insulation, petroleum anticoagulation heat tracing, etc.
► Tank antifreeze heating system
The main components of the tank pump valve antifreeze heating system: electric heat tracing control box, self-limiting electric heat tracing, power junction box, terminal junction box, temperature sensor, insulation layer, heat-resistant pressure-sensitive tape, aluminum foil tape, fixed steel belt, 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.
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.
►How it works
The temperature sensor on the tank body will sense the temperature through the signal cable to the temperature control instrument in the electric heat tracing control box, the temperature control instrument will receive the temperature compared with the set temperature, when the current temperature is greater than the set temperature, the electric heat trace will not work, when the current temperature is less than the set temperature, the electric heat trace starts to work, in order to avoid frequent start-up, generally set a return difference, the electric heat tracing control box can also be connected with the central control room or DCS system for remote communication, and the start and stop of the electric heat trace can be remotely observed and controlled.

Product features: The advantages of self-limiting electric heat tracing: small starting current, low power distribution cost in the early stage, 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 of the tank is polished smooth without burrs and sharp edges, dry and free of dirt; Check whether the paint of the tank is dry and the gas has volatilized for more than 3 weeks; 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: when installing electric heat tracing on the tank, the surface of the tank should generally be smoothed first, and then a layer of barbed wire mesh should be laid on the tank (or paste insulation nails or welding hooks on the tank, etc.) on the tank, and finally install the electric heat tracing, after the installation is completed, cover a layer of aluminum foil tape along the direction of the electric heat tracing, which is used to increase the heating area of the tank, and the installation spacing is obtained by calculating the heat dissipation and surface area of the tank.
