Maximum holding temperature of electric heat tracing belt

Maximum holding temperature of electric heat tracing belt

If the heat transferred to the system per unit time is equal to the heat transferred to the environment by the system, the temperature of the system can be maintained constant when using an electric heat tracing belt to heat a certain system.

Maximum acceptance temperature

Capable of accepting the influence of external heat sources below one degree temperature, above which the power will gradually decrease and become agglomerative. Therefore, do not exceed the maximum acceptable temperature of the electric heating strip during use. This parameter is the main parameter for selecting electric heat tracing belts.

Maximum surface temperature

Place an electric heat tracing strip of sufficient length in a sealed container with excellent insulation, and the maximum temperature reached under additional voltage is the highest surface temperature of the electric heat tracing strip. This parameter is important for situations with flammable fuels or explosive gases.

Maximum operating length

Electric heating strips can be cut and used arbitrarily, but can only be extended freely within a certain length range; In other words, the maximum operating length must not be exceeded. The maximum operating length is related to additional voltage, power standards, and the minimum ambient temperature during operation. If the required length exceeds the maximum length of the electric heat tracing cable, a separate power source should be connected or a specialized electric heat tracing cable with special standards should be used. The strip constant temperature family is accustomed to heating systems, while traditional constant power heaters have an impact on the heating system. As the system temperature increases, the power roughly decreases linearly. Its slope is the decrease in power of the electric heating strip for each degree of change in system temperature, which reflects the ability of power to actively adjust with temperature.
