What is a heat exchanger?
It is used to warm or cool a product by exchanging heat between the process fluid and a service fluid,which is typically water, ice water, glycol or steam. The hot or cold service fluid flows around the tubes within the tubular heat exchanger and heat is transferred between the product and the media.

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.

We are manufacturers of all types of heat exchangers in Coimbatore India. We design and manufacture Double Plate Type, Shell and Tube, Air Cooled Heat Exchanger, Air Cooled Condenser, etc.
Condensers are used for condensation of vapors and cooling of liquids. Condensers are made by fusing number of parallel coils in a glass shell. Coils are made in different diameters using tubes of different bores.
Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa. The fluids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes. In this way, waste heat can be put to use. This is an efficient way to conserve energy.
