Stainless Steel heat exchanger
The stainless steel heat exchanger is a kind of heat exchanger made of stainless steel, which has good oxidation resistance, safety and health. It is widely used in food, medicine, heating, domestic water, air conditioning return water and other fields. According to the data of the heat exchange equipment promotion center, the stainless steel heat exchanger has better heat transfer effect than the traditional carbon steel heat exchanger and has a longer service life. The stainless steel heat exchanger has been widely used in many fields. The heat exchanger is made of food-grade stainless steel, which has outstanding anti-rust and anti-scaling properties.
Performance characteristics
1.The heat transfer coefficient of the heat exchanger is 6000-8000W / m2.0c.
2. It is made of stainless steel and has a long service life of more than 20 years.
3. Changing laminar flow to turbulent flow improves heat transfer efficiency and reduces thermal resistance.
4. High heat transfer speed, high temperature resistance (400 ℃), high pressure resistance (2.5MPa).
5. Compact structure, small floor area, light weight, convenient installation and saving civil engineering investment.
6. Flexible design, complete specifications, practical and targeted, saving money.
7. Wide application conditions, suitable for large pressure, temperature range and heat exchange of various media.
8. Low maintenance cost, easy operation, long cleaning cycle and convenient cleaning.
9. Using nano hot film technology, the heat transfer coefficient is increased significantly.
10. It can be widely used in thermal power, factories and mines, petrochemical industry, urban central heating, food and medicine, energy electronics, machinery and light industry and other fields.
