far infrared quartz heater component voltage is 110/220v/380v or other voltage grades needed by users. length 300 - 3,000 mm;outer diameter:10-50mm;power: 0. 3-6kw. our company can also process, design, produce goods according to each technical parameter of user's special request. 2． surface temperature of heater divides into three grades: low temperature: 400℃ --600℃ mid temperature: 600℃ --800℃ high temperature: 800℃ --1000 ℃ 3． relative radiation characteristic: this quartz heater component has strong transmission at far infrared, compared with other kinds far infrared products, when the wavelength>6, radiation energy is particularly remarkable. 4． the spectrum emissivities: the quartz heater the component have no coating, and milky white quartz tube playing a radiation role promptly, also supporting and insulate role. 5． radiation rate is high, and hot inertia is small, milky white quartz tubes' hot energy is only 10% of the carborundum and metal tube, hot inertia is<20 seconds. it is specially suitable for the production technology of the intermittence type , the continuous type is better! lianyungang granhtquartz factory
