A detailed description of the antifreeze measures for laboratory ultrapure water heater in winter

       The ultra pure water device in the laboratory adopts microcomputer full-automatic intelligent control, touch keyboard, power on self-test, water shortage protection alarm and power-off protection. It is specially used for hospital laboratory, blood station, Research Institute, biochemical instrument, supporting pure water machine and other biochemical, physical and chemical testing water.

In winter, as the temperature gradually decreases, the laboratory ultrapure water heater used in the North may freeze or crack under low temperature conditions. If it is installed outdoors, anti freezing measures must be taken. If there is no anti freezing measures, it may lead to freezing crack of filter bottle and membrane shell. If the temperature is below zero, the water purification equipment must be stopped The room temperature of the water treatment equipment installed indoors must not be lower than 0 ℃. The volume of water treatment equipment will expand during solidification. If it freezes, all pipelines, filter bottles, membrane shells, etc. of the water purification equipment will burst, resulting in water leakage

If the water treatment equipment is not used for a long time or needs to go out, the water inlet ball valve must be closed to drain all the water in the pressure bucket. Before reuse, check whether the appearance of the machine is normal, and turn on the water source and power supply after confirming that it is normal. It is also recommended to drain the prepared bucket water.

In case of icing, the water purification equipment must be placed in the room with the room temperature higher than 10 ℃ for natural thawing for 48 hours before it can continue to be started for use. During this period, it is not allowed to force the start-up to make water. Check whether there is water leakage after the start-up. Safety of equipment: it refers to the safety of process and technology, which can ensure to meet the required indicators Material of water treatment equipment: what the water treatment device needs to see is the tank material At present, there are stainless steel, FRP, cast iron, aluminum, food grade resin or PVC and other materials on the market. Function: purified water is to remove sediment, impurities, bacteria, heavy metals, residual chlorine, organics and some minerals Softened water is to remove calcium and magnesium ions in water, which directly means scale Generally, softened water only needs cation resin to complete ion exchange and remove calcium and magnesium ions.

To sum up, the anti freezing measures shall be taken to ensure the normal operation of the equipment in the laboratory in winter.
