Water system central air conditioning auxiliary electric heater. Products include spray type, stainless steel, electric heating is mainly used for central air conditioning to automatically compensate in the case of winter thermal attenuation and low ambient temperature, and can be based on host water temperature The high and low to achieve automatic work. Our company is electric heating with high temperature protection and temperature adjustment (30-110 degrees) function, the product safety system is extremely high, can be connected to the host, fully automatic control. Internal heat inside the electric heating Layer, no need to heat preservation, easy to install Second, the precautions during use 1, the wiring portions should be placed outside the insulation layer, avoid contact with corrosive, explosive medium, and moisture; leading line should be long-term Under the temperature of the wiring portion and the heating load, it should be avoided when the wiring screw is tightened. 2, the electric heating tube should be positioned well, and the effective heat generation area must be impiltrated into the liquid or metal solid, which is strictly prohibited. When the surface of the tubular body is scales or junction, it should be cleaned in time to avoid the use of life. 3, the components should be stored in a dry place. If the long-term placement of the insulating resistance is less than 1mΩ, it can be dried in an oven at 200 ° C, or the voltage is electrically hot until the insulating resistance is restored. When heated, it is easy for metal or solid nitro salts, alkali, bitumen, and stone wax, and should reduce the use of voltages. After melting to be medium, it can rise to the rated voltage. 4, when the heating air should be uniformly arranged, so that the elements indoor heater have good heat dissipation conditions, so that the flowing air is fully heated. 5. Safety measures should be considered when heated nitric salts and prevent explosives. 6, the electric heating element allows to operate under the following conditions: A, the air relative humidity is not more than 95%, no explosive and corrosive gases. (Except of explosion-proof electric heaters) B, the operating voltage should not be more than 1.1 times the rated value, the outer casing should be effectively grounded. c, insulation resistance ≥ 1 MΩ dielectric strength: 2kV / 1min. Wiring portions should be placed outside the insulation layer, avoid contact with corrosive, explosive media, and moisture; the leading line should be able to withstand the wiring portion for a long time Temperature and heating load, should avoid excessive force when the wiring screw is fastened. 7, heating for easy melt metal or solid nitro salts, alkali, bitumen, stone, etc., should reduce the use of voltages, after melting, to be melted to rise to the rated voltage. 8. The magnesium oxide powder of the electric heating tube is used to avoid penetration of pollutants and moisture in use, prevent leakage accidents.
