D type electric heater is composed of axial flow fan (aluminum alloy impeller, motor and net cover as a whole), electric heater, shutters and outer shell. The shell is fully anticorrosive treated inside and outside, and the surface is sprayed with plastic; the metal shell has high fire resistance. The fan adopts domestic advanced low energy consumption, high temperature resistance, low noise, oil-immersed motors; the electric heater uses PTC material. The heating element is characterized by fast heating, low power consumption, long life, high thermal efficiency, safety, reliability, energy saving and environmental protection. Due to the resistance and temperature characteristics of the PTC element, the heating temperature rise is automatically controlled at about 200 ° C to ensure that there is no redness on the surface of the heater to avoid accidents. The heater adopts 380V star connection method (with zero line). Applicable environment: ◆ Applicable to areas 1 and 2 of explosive gas environments; ◆ Applicable to ⅡA, ⅡB, and IIC explosive gas environments; ◆ Applicable to environments with temperature groups T1 ～ T4; ◆ Applicable to petroleum extraction and storage Explosive and dangerous environment such as chemical industry, drying room, power equipment and facilities; Explosion-proof heater is divided into explosion-proof floor heater and explosion-proof wall-mounted heater. Let the air circulate and heat.
The company produces explosion-proof heaters with a unique temperature control system, which can realize artificial intelligence, automatically turn on and off, without manual operation. The specific functions are as follows: 1. Temperature setting: "Starting temperature" and "Stop temperature" are set separately. Press the "arrow" of "down" or "up" to start setting the "start temperature" and "stop temperature". When the set temperature reaches the required temperature, the temperature at this time is the temperature you set. Start: Set the "Starting Temperature" to be greater than the "Stop Temperature", and the thermostat is in the "High Temperature Startup" state. For example: Set "Stop temperature" to 20 ° C and "Starting temperature" to 30 ° C. When the measured temperature reaches 30 ° C or higher than 30 ° C, the machine turns on and the running indicator (green light) turns on. Outlet power. When the measured temperature drops to 20 ° C, the machine is turned off, the standby indicator (red light) is on, and the socket is powered off. 3. Low temperature start: Set the "start temperature" to be lower than the "stop temperature", and the temperature controller is in the "low temperature start" state.
For example: Set the "stop temperature" to 30 ° C and the "starting temperature" to 20 ° C. When the measured temperature reaches 20 ° C or less than 20 ° C, the machine is turned on and the running indicator (green light) is on. At this time, the socket powered by. When the measured temperature rises to 30 ° C or higher than 30 ° C, the machine is turned off, the standby indicator (red light) is on, and the socket is powered off. The D20D40 explosion-proof electric heating heater is a heating device used to centrally transport a large amount of hot air. Due to the use of 9-57 centrifuges, it has a high residual pressure and a large air speed. It can be used in the design of heating systems for centralized delivery machines, and is widely used in the production workshops and large buildings of various industrial and mining enterprises. D20D40 electric heating heater works: D20D40 explosion-proof electric heating heater is mainly composed of air heater and fan. The heat medium (can be steam, water, electricity) passes through the air heater, and the wind from the fan takes away the heat emitted by the heater, so that the indoor air temperature can be increased.
