  • Why infrared?

    Benefis of short wave infrared radiation lamps compared with other radiating elements  

    Efficinecy: 92% of the energy consumed is transformed into infrared radiation and hence into heat,Ablity to direct the radiation:As with light,it is not affected by air currents ,there is no loss of enery,and the heat is applied where it is neeeded. 

    Versatility: The power input can be adjusted between 0% and 100% without any effect on lifespan. 

    Cleanliness and Safety: No noise,dust or smoke. 

    Compactness : Optimal power density.

  • What is electric heating system ?

    An infrared heater is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the infrared radiation ranges from 780 nm to 1 mm. The relationship between temperature and wavelength is expressed by the Wien's displacement law. No contact or medium between the two bodies is needed for the energy transfer. Infrared heaters can be operated in vacuum or atmosphere.

    One classification of infrared heaters is by the wavelength bands of infrared emission.Short wave or near infrared for the range from 780 nm to 1,400 nm, these emitters are also named bright because still some visible light is emitted;Medium infrared for the range between 1,400 nm and 3,000 nm;Far infrared or dark emitters for everything above 3,000 nm.

  • How about your delivery time?

    Generally, it will take 15-25 days after receiving your advance payment. The specific delivery time depends on the items and the quantity of your order.

  • Are you a factory or trading company?

  • Do you test all your goods before delivery?

    Yes, we have 100% test before delivery.

  • What is your sample policy?

    We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.

  • Attention?

    1 .If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
    2. The heater must not be located immediately below a socket outlet.
    3. Do not use the same socket together with other appliances, in case of current overload. Make sure the plug and socket good contact.
    4. Please pull plugs out when power off. Be care,do not pull wires by hands.
    5. Please stop power immediately once heaters failure or wires are broken. Users can not repair heaters by themselves. Please contact authorized servicer for maintenance if heaters failure.
    6. Radiant heater can not be placed directly below the power outlet.
    7. Radiant heater surface temperature is high, must be installed higher than 1.8 meters above ground.
    8. Radiant heater surface cannot becovered and can not hang objects on equipment.
    9. The distance between back of radiant heater and roof should be larger than 150mm, can not objects within 1000mm distance in front of heater, the side should be kept at least 200mm away from the surrounding space.
    10. Must cut off power and wait till equipment surface cool before cleaning,flushed by water is prohibited.
    11. Users can not repair the radiant heater, if equipment failure and need maintenance, please contact authorized servicer.
    12. Do not install and use radiant heaters on areas occur with flammable, explosive, easy to shock.
    13. Please do not insert any metal or foreign objects to inside of radiant heater, to avoid accident or personal injury.
    14. Radiant heater panel surface with high temperature, touch is forbidden, prohibit touch,beware of scalding accident.
