Water Heating System

ST series 420

In the process production of pharmaceutical and chemical enterprises, steam heating is needed to realize process insulation or hot water circulation heating of the process. In order to meet the needs of our customers, according to our many years of production experience, we specially designed a hot water temperature control device with steam as the heat source and constant temperature water as the water source.

Technical Parameters:

1. Heat medium: saturated steam pressure: 0.5MPa and above, temperature: 158.8 ℃ and above

2. Hot water control temperature RT + 10 ℃ ~ 135 ℃

3. The process water is circularly heated by using the pipe type steam and water mixed heat exchanger;

4. The steam shall have low noise, no vibration and high thermal efficiency in the use of heat exchange process;

5. The service life of steam and water mixed heat exchanger is more than 15 years, so as to achieve once and for all;

6. The temperature of process hot water is constant without manual duty and fully automatic control.
