            Application principle and function characteristics of electric heater

            author:click:67 release time:2021-02-19

            In the process of using the external components of electric heater, the following criteria should be followed:


            First of all, we should fully understand the temperature requirements of the electric heater, and select the appropriate air duct electric heater equipment. Generally speaking, the higher the power, the faster the heating, and vice versa.


            Dry burning of electric heater equipment is strictly prohibited, especially invasive electric heating elements, which are made of stainless steel 304.


            Choose the appropriate power of electric heating tube, in the premise of ensuring the invalid use temperature, we should pay attention to the load performance of power.


            Fully understand the application environment of electric heating tube, medium conduction or infrared radiation, etc.


            Fully understand the wiring mode of electric heater, usually star connection and three-star connection, single electric heating tube can be connected to 220 V or 380 V, multiple electric heating tubes can be indirectly connected to 380 v.


            Features of electric heater:


            Small size, high power: the heater mainly uses cluster tubular electric heating elements.


            It has fast thermal response, high precision of temperature control and high comprehensive thermal efficiency.


            High heating temperature: the heater design is high, and the task temperature can reach 850 ℃.


            The medium outlet temperature is average and the temperature control precision is high.


            Wide range of application and strong adaptability: the heater can be used in explosion-proof or ordinary places, with explosion-proof grade of D Ⅱ B and C, and pressure resistance of 20MPa.


            Long service life and high reliability: the heater is made of special electric heating materials, designed with low power load and multiple maintenance, which greatly increases the safety and service life of the electric heater.


            Fully automatic control: according to the requirements of the heater circuit design, it is convenient to complete the automatic control of outlet temperature, flow, pressure and other parameters, and can be connected with the computer.


            The energy-saving effect is obvious, and almost 99.99% of the heat generated by electric energy is transferred to the heating medium.
