Micro-computer controlled superconductor electromagnetic heaterMicro-computer controlled Super-conductive Electromagnetic Heater Energy-saving, Environmental protection, Safety, Durability. New patent Products Energy-saving 40-50% to the traditional electrical-heater. Working principle: Micro-computer controlled Super-conductive Electro-magnetic Heater uses electro-magnetic induction to heat, rectifying circuit converts 50Hz AC to DC, then converts DC to 20-30KHz high frequency voltage by controlled circuits. High-speed changed current produces high-speed changed electro-magnetic field through coils. When magnetic line of force passes the bottom of metal container, it will produce unlimited small bow waves to heat the container rapidly, then hat the super-conductive liquid inside the container, the heat is radiated into air through inner circular system.. Main characteristics: Heat rapidly, energy-saving greatly, safety and durability. Time-setting ,Temperature adjustable. The heater system uses super-conductive medium, not water, so no need maintenance .No corrode, no air block, no waste steam, liquid and material. To heat the air by using magnetic field induction, so no radiation of any material. No flame, no smoke, no smell. So it is suitable for any places, even the places that fire is strictly forbidden, such as petrol station, gas center, liquor factory, workshop, warehouse etc. Because there is no water in the system, so there is no waste water, waste gas released. It is truly environmental protection. Temperature adjustable from 5-30 degrees. Time-setting date ,time and times. Switch on and off automatically, telephone remote temperature controller can control the time of switch on and off. Super safety, the system has over-current protection, over-voltage protection, over-heat of power tube protection and phase compensation etc. Power: 220V±10% 50Hz 380V±10% 50Hz Art No. Power Suitable for the house ㎡ DNQ8 800W 8-10 DNQ10 1000W 10-15 DNQ13 1300W 15-18 DNQ15 1500W 18-20 DNQ18 1800W 20-25 DNQ20 2000W 25-30
