BVR heat exchangers provide the optimum solution for every requirement encountered in practice because of the wide range of types available. This applies not only to coil type heat exchangers, which are available as condensers, boilers and immersion heat exchangers, but also to shell and tube heat exchangers, which are designed for use with tubes in various possible corrosion resistant materials.

These items are widely used in the chemical, pharmaceutical and allied industries together with other applications such as food and drink production and dye works. This is because of the special properties of borosilicate glass 3.3 and all the other materials used plus the fact that borosilicate glass 3.3 is an approved and proven material of construction for pressure vessels.

These are fabricated with all major internationally prevalent buttress design and having a very high reliability of the strong and high-duty coupling system used for all components

The complete range of standard heat exchanger components is described ahead. Non-standard & special custom designed components can also be supplied to special order.

SHELL & TUBE HEAT EXCHANGER
Shell and tube heat exchangers provide a versatile alternative to the coil-type heat exchangers. These can be used as condensers, but are equally suitable for heat transfer between two liquids or gases.

These shell and tube heat exchangers are of modular construction. They comprise the following individual elements: tubular shell, headers, tube plates, heat exchange tubes and baffles. Sealing of the individual tubes in the tube plate is of particular importance. The threaded PTFE bushes and PTFE sealing rings provide a seal of the highest integrity between the different materials.

Shell & Tube heat exchangers offer large surface area in combination with efficient heat transfer and compactness. These are widely used in industries for various duties like cooling, heating, condensation, evaporation etc.
Salient Features :
Universal corrosion resistance an excellent alternative to expensive MOCs like graphite, hastelloy, copper titanium, tantalum and other exotic metals.
Excellent heat transfer as fouling does not occur on smooth glass surfaces.
Flexibility of installation vertical/horizontal.
Easy replacement of tubes for repair and cleaning.
Available in wide range of HTAs.
Ease of installation due to light weight.
Economical.
Suitable for applications where large HTAs are required in limited space.
Construction Features :
The glass tubes are sealed individually into PTFE tube sheet with special PTFE sockets and packing. This unique ferrule type sealing arrangement permits easy replacement and cleaning of tubes. Baffles on shell side ensure improved heat transfer by increased turbulance. Further details of construction an be seen in the diagram.

Range Of Applications :
Permissible temperature range for both shell & tube sides - 400 C to 1500 C.
Maximum permissible temperature difference between shell & tube sides = 1200 C.
All sizes & modes are suitable for full vacuum on both side. Maximum limiting pressures are tabulated here below :

The above ranges of applications are admissible limiting values. In actual practice we can recommend the right selection on the basis of prevalent temperature – pressure parameters.
Performance & Design Data :
The particular advantage of shell & tube heat exchanger is high heat transfer performance. The relation between heat transfer and velocity of flow can be easily seen in the diagram. On receipt of the operating data from client the most favourable shell and tube heat exchanger is selected. This accurate design combined with most reliable quality assurance ensures economy and operational reliability for the user.
