High flux pipe is specifically designed to enhance heat transfer coefficient. A thin, porous metal layer is bonded metallurgically to the heat transfer surface. This pore make liquid produce a large number of bubbles at low superheat, which enhance heat transfer. At the same time, porous structure formed many boiling centre, the film boiling changes to nucleate boiling. So boiling side heat transfer coefficients of 10-30 times that of bare tubes can be achieved, resulting in an overall heat transfer improvement of 2-4 times that of bare pipes.
The main application:
Overhead cooler
Reboiler of ethylene separation
Ethylene glycol unit evaporation tower
Seawater desalination etc.

Double-direction fresh air exchanging system, high efficiency and energy and energy saving. With the preliminary filter, it can filter the dust particles and purify the air. Thin body design makes it suitable for any kind of ceiling installation. It's with double speed switch which is easy to install.
Pshe consists of a circular plate group and shell. The plate group, enclosed in the pressure vessel, is the core of the heat exchanger. As heat transfer components, plates determine the heat transfer performance of the heat exchanger. Shell is the essential for the temperature, pressure capacity and safe and reliable operation.
Based on specific operating parameters, media flow paths can be set properly, which ensures the reasonable match of heat transfer efficiency and the resistance loss, and at the same time minimizes equipment investment and operating costs.
Plate & frame type heat exchanger is a fully welded plate and frame heat exchanger, which consists of a fully welded plate group and removable covers. Four covers can be opened from four directions for the inspection, maintenance and cleaning of the plate group. By adjusting the flow structure and the installation position of the partition, it is suitable for different working conditions.
Plate corrugation will match with medium properties.
With compact structure, this kind of heat exchanger has high heat transfer efficiency.
A graphite heat exchanger is a device built for efficient heat transfer from one corrosive medium to another. The media may be separated by two parallel channels, so that they never mix, or they may be in direct contact.They are widely used in chemical plants, petrochemical plants, pharmaceutical factory, and so on.
Shell and tube heat exchangers consist of a series of tubes. One set of these tubes contains the fluid that must be either heated or cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc. Shell and tube heat exchangers are typically used for high-pressure applications (with pressures greater than 30 bar and temperatures greater than 260°C). This is because the shell and tube heat exchangers are robust due to their shape.
Features
1. Tube diameter: Using a small tube diameter makes the heat exchanger both economical and compact. However, it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of the fouling difficult.
2. Tube thickness: The thickness of the wall of the tubes is usually determined to ensure:
a. There is enough room for corrosion
b. That flow-induced vibration has resistance
c. Axial strength
d. Availability of spare parts
e. Hoop strength (to withstand internal tube pressure)
f. Buckling strength (to withstand overpressure in the shell)
3. Tube length: heat exchangers are usually cheaper when they have a smaller shell diameter and a long tube length. Thus, typically there is an aim to make the heat exchanger as long as physically possible whilst not exceeding production capabilities.
4. Tube pitch: when designing the tubes, it is practical to ensure that the tube pitch (i.e., the centre-centre distance of adjoining tubes) is not less than 1.25 times the tubes' outside diameter.
5. Tube corrugation: this type of tubes, mainly used for the inner tubes, increases the turbulence of the fluids and the effect is very important in the heat transfer giving a better performance
At present,floating coil heat exchanger is the new product improved on the basis of former products. Now it has been the Generation VI Product by our continued optimizing and improving. Because we use the smaller heat transfer component, it has tight structure and reasonable layout The moreover, the decrease of outer size has solved the problem short flow caused by uneven flow velocity on the circular cross-section of former shell side, therefore its potential functions of high heat transfer coefficient K and stable thermostatic water supply can be brought into to the full play.
The managerial principle of our company is “Quality First, User First”. We break constant policy, and constantly update the design plan to make the best better, we always try our best to win over the user and market by perfect quality and functions in order to expand and develop our company.
The floating coil heat exchanger can be widely used in the supply system of heating,air conditioning and domestic hot water in the industrial and civil buildings just like hotels,restaurants,organs,schools,hospitals,laundries,factories and so on.
