Product Description

Electro-thermal Film coated quartz tube brief introduction

Mainly used for liquid heating except hydrofluoric.

Technology:

Crystallite electric heating film is such a technology that changes the surface properties of the base material and turns it into a new electro-thermal material. This process is realized in gas phase, a variety of chemical elements undergo complex physical and chemical reactions in the form of atom, molecule or ion, during which a conductive film consists of atomic and ionic bond is formed on the surface of base material.

Features:

Safety:

Isolation of water and electric, so that avoid accident caused by electric leakage.

Efficient and energy-conservation: More than 96% electrical energy is converted into short wavelength infrared radiation.

Non-luminance: Working below 300℃,it won't give off light; clean, environment-friendly, energy-conservation. And almost no power decrease working below 300C.

Easy temperature control: Fast temperature increase, even heat coverage, easy precise temperature control.

Wide available voltage range: Working voltage rang from 12V~380V, power from 300W to 4000W per single tube.

Durable and long lifetime

Low start-up current, complete parallel circuit, corrosion resistance. Isolation of water and electric, so that avoid accident caused by electric leakage. Up to 30000hours life.

No Scale

Electric film carrier for quartz glass, and quartz glass is not easy to scale, and could keep 98% electric conversion rate during long-term use, which is 20~50% energy saving than Metal electric heating pipe (Metal electric heating pipe will case scale then leads to decrease of electric conversion rate)
