Chemical glass condenser operating instructions and precautions:
1. Before installation, fill the condenser coil with water, plug one port, inflate the other port by 0.1 MPa, and check for no cracks or leaks before installation.
2. Coil condenser is prohibited to be used horizontally. Rubber or plastic tubes with an inner diameter less than or equal to ≤20 mm should be used to minimise all kinds of external stresses generated during installation. At the same time, strong vibration caused by stirring and negative pressure pumping should be avoided. Also note that the gas phase cannot flow in the same phase as the cooling water. After installation, slowly drain the water first, then open the water valve, and wait for the outlet to see water before slowly warming up. When using, do not allow a sudden lack of water or sudden sharp rise, the diameter of the outlet pipe is larger than the diameter of the inlet pipe. It is recommended to have the conditions of zui can make good use of the downstream negative pressure into the water, not only can reduce the pressure of the coil, but also can prevent the coil in the over-temperature and over-pressure process of sudden damage to the kettle after the water into the kettle.
3. Regularly remove the scale in the coil with acid to prevent blockage affecting the cooling effect or damage.
4. When running, turn on the cooling water first, and then turn on the heat source. When shutting down, turn off the heat source first, and then turn off the cooling water.
5、When stopping in winter, turn off the cooling water to prevent the glass equipment from freezing and cracking.
Heat exchanger is widely used in chemical, pharmaceutical, food and other related industries. It is characterised by large heat transfer area, high heat transfer efficiency and qualified flow rate.
Coil heat exchanger is mainly used for condensation and cooling, but also can be used for heating liquid heating carrier. The heating of saturated steam is limited to heat exchangers with a heat exchanger area of no more than 1M2.
The main structure of the coil heat exchanger is high borosilicate glass (borosilicate glass 3.3), i.e. the heat exchanger tubes are sealed with the shell. It has the following advantages.
-No need for sealing between casing and tube end.
--Strong corrosion resistance due to the use of borosilicate glass 3.3.
--Because of borosilicate glass 3.3, heavy metals and impurities do not separate, providing a good environment for manufacturing products.
--Flexible assembly, can be connected in series or parallel to meet the needs of different heat exchange area.

Scope of application.
--Corrosion resistance includes all organic and inorganic media. Except hydrofluoric acid, fluoride, phosphoric acid and concentrated acid at high temperature.
--Allowable working temperature:180℃; Maximum allowable temperature difference:120℃.
--Allowable working pressure.
Atmospheric pressure:0.1 MPa
Negative pressure:The pressure difference between shell and tube side shall not exceed 0.1 MPa.
