D90 electric heater, high-power D90 explosion-proof electric heater, coal mine wellhead explosion-proof heater

Description :

　　1、 D90 electric heater is suitable for:

　　The D90 explosion-proof electric heating system uses electric auxiliary heating as its energy source and is suitable for hot air heating in workshops, civil defense projects, field operations, factories, mines, enterprises, production workshops, and large buildings.

　　2、 Installation, use, and maintenance of D90 explosion-proof electric heating heater

　　1. When installing the D80 electric heating heater, first check if the machine is in good condition.

　　2. Valves should be installed on the inlet and outlet pipes of the heat exchanger, and the diameter of the inlet and outlet main pipes should be larger than that of the heat exchanger.

　　3. The temperature of hot water used in the heat exchanger should not exceed 130 ℃, and the pH value should not exceed 8 to avoid reducing its service life.

　　4. The motor bearings should be cleaned once a year and lubricated with oil.

　　5. Before testing the machine, turn on the fan blades and check for any scratches or collisions between the fan blades and the machine. When turning on the D80 electric heating heater, pay attention to the direction of motor rotation, which should be the same as the direction indicated by the arrow label.

　　3、 Environmental conditions for the use of explosion-proof warm air fans at coal mine shafts:

　　1. Environmental temperature: -20 ° C+40 ° C

　　2. Relative humidity of the environment: ≤ 98% (+25 ° C)

　　3. Atmospheric pressure: 86kPa-106kPa

　　When the ventilation room is located outside the industrial square, except for mines with gas emission areas and coal (rock) and gas outburst mines, flameproof furnaces or explosion-proof electric heaters can be used

　　Our company produces industrial hot air curtains, through flow centrifugal type, hot water steam type electric heating type, etc. We also produce D-type warm air fans and electric heating type warm air fans. These warm air fans can be used in industry or for blowing warm air at coal mine shafts, with explosion-proof or non explosion-proof options. For more details, please call us. Thank you!
