Shell and tube Heat Exchanger are for large heat transfer area, theefficiency of heat transfer and compactness. Shell and Tube Heat Exchanger are widely used as coolers, Condensers, Heaters and Evaporators.Glass Shell and Tube Heat Exchangers are reliable only when leak-free sealing is available between shell & Tube sides. There are two types of Ferrule Sealing in Sigma shell and tube Heat exchangers. Such as:

• PTFE Ferrule with Gland Packing.
• PTFE Ferrule without Gland packing.

In thecase of Ferrule seal with gland packing PTFE O Ring & PTFE Rope is used to fill the space between tube and tube sheet and PTFE Ferrule acts as a Gland Follower to make sealing perfect and leak free.

And Ferrule without gland packing is a sealing system where the design of ferrule is such that while tightening. The ferrule gets folded at the seal point of Tube Sheet in such a way that it does not require O Ring or the gland rope and gives as good leak free sealing as in the first case.

This unique ferrule type sealing arrangement permits easy replacement and cleaning of tubes.

Sigma has further improvised on theshell and Tube Evaporators and Re-Boilers with thereplacement of Glass Tube by Graphite Tubes and GFT Tube Sheets. These types are good for high temperature and high-pressure application.

SIGMA heat exchangers provide theoptimum solution for all requirements encountered because of the wide range of heat exchangers available. Heat exchangers are used for condensation of vapours or cooling of gas or cooling of liquids. Two basic types of glass heat exchangers are available, Coil type and Shell and tube type. Glass coil type heat exchangers are available as condensers, boilers and immersion heat 2 exchangers with heat transfer areas up to 8m. Shell & tube type heat exchangers are designed for use with tubes in thewidest possible range of corrosion resistant materials. Shell & tube type heat exchangers are available with glass or Mild Steel (MS) Shells in combination with glass tubes as standard. The advantage of using Shell & Tube type heat exchanger are larger heat transfer area in single unit, Low-pressure drop, Easy tube replacement.
