30TR Shell and Tube Heat Exchanger

Water Cooling Evaporator

Considering the flow relationship between the heat transfer tubes, the heat transfer tubes and the shells,

the turbulence is no longer forced by the baffles, but the alternating vortices are naturally induced by the

heat transfer tubes. In order to ensure that the heat transfer tube does not friction with each other under

the premise of maintaining the required vibration. Heat transfer tube rigid and flexible configuration is

good, not collision with each other, not only to overcome the floating coil heat exchanger collision between

the damage caused by the problem, but also to avoid the ordinary shell and tube heat exchanger easy to

fouling problems.

1. Energy efficient, the heat transfer coefficient of 6000-8000W / m2.0C.

2. All stainless steel production, long life, up to 20 years.

3. The laminar flow is turbulence, which improves the heat transfer efficiency and reduces the thermal

resistance.

4. Heat transfer speed, high temperature (400 ℃), high pressure (2.5Mpa).

5. Compact structure, small footprint, light weight, easy installation, saving civil construction investment.

6. Design flexibility, complete specifications, practical targeted, saving money.

7. Wide range of applications, for greater pressure, temperature range and a variety of media heat

exchange.

8. Maintenance costs are low, easy to operate, cleaning cycle is long, easy to clean.

9. Using nano-film technology, significantly increase the heat transfer coefficient.

10. Wide range of applications, can be widely used in thermoelectric, factories and mines, petrochemical,

urban central heating, food and medicine, energy electronics, machinery, light industry and other fields.
