No jacket quartz, Teflon heat exchangers, Teflon switches, Teflon heaters, ..

1. Quartz electric heater is not suitable for heating the solution containing hydrofluoric acid and alkaline solutions, long-term use in such liquid quartz tube surface is easy to dissolve perforation. 2. When the aluminum oxide solid acid polishing and deposition of liquid heating, the need for acid in the solid deposits regularly cleared, so as not to adhere to the surface of the quartz tube, resulting in a low melting point compounds, corrosion damage quartz tube. 3. Low surface power design (4.5W / CM2), thickening of the solution heated applying a low surface power (2.5W / CM2) designed to ensure the life of the product. 4. All heaters can be over-temperature protection at the beginning or supporting the use of temperature probe. 5. All heaters are adopt international inspection standards to ensure the safety of electrical performance and stability.
