Requirements for cooling effect and heating power of standard COD digesters

KHC0D-8Z standard COD digestion device

Condense, heat bottle

After more than 10 years of user use, there are several aspects have been improved: 1, electric furnace plate: silicon carbide electric furnace plate surface uneven, uneven heating phenomenon, and it is very difficult to cool; Now the selection of new energy-saving and environmental protection template materials, high-quality coarse diameter low function heating wire, glass-ceramics heating table, to solve the problem that customers need to solve. 2. Control panel; Control panel with start, timing, air cooling, three keys, display window only digital display heating time countdown, there are also LCD display, Chinese menu operation, display real-time change temperature and digestion time countdown. 3, cold; Single fan cooling small condensation, has been changed to double fan cooling, large and high 3 bubble burr condensation.

The information illegally crawled from experience

Standard COD digester heating power requirements: the standard COD digestion device uses a special electric heating plate heating, microcrystalline glass table, the overall structure, reasonable space separation design, microcrystalline heating plate is a single piece, installation and replacement of the electric furnace plate is very convenient and simple, heating the surface of the electric furnace plate uniform heating, heating, cooling speed. Sample solution accidentally dripped on, easy to clean up. The normal heating power of 8 samples is 1600w, and the thyristor voltage and temperature control heating is adopted. In the case of no need to reset, the potentiometer can be arbitrarily adjusted to change the heating power, so as to ensure the boiling temperature of the sample and let the sample boil in a satisfactory state.
