Water Heating System

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.
