Description

Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact.

Heat exchangers can improve a system’s energy efficiency by transferring heat from systems where it is not needed to other systems where it can be usefully used.

Applications:

Heating a cooler fluid using the heat from a hotter fluid
Cooling a hot fluid by transferring its heat to a cooler fluid
Boiling a liquid using the heat from a hotter fluid
Boiling a liquid while condensing a hotter gaseous fluid
Condensing a gaseous fluid by means of a cooler fluid

Specification

Fixed tube exchanger

Low cost because of simple structure
Muti-pass shell available
Easy cleanning by removing the head: but not for the dirty fluid

U tube exchanger

Only one tube sheet in U shaped
Tubes can freely expand, which is suitble for high temperature difference

Floating head exchanger

One head is free to expand or floating in the shell side
Applicated in high temperature difference, as the tubes are free to expand
The floating head cover can be easily removed
Dirty and fouling services can also be used
The most versatile exchanger but respectively expensive

Features

High heat transfer coefficient
High pressure and high temperature application
Less solid fouling;
Less floor space and compact design
Tube material: CS, Aluminium, Stainless steel, Titanium, Copper alloy, Inconel, Nickel, Hastelloy
Shell material:CS, SS304, SS316, Titanium, Alloy steel, Copper .
Other materials available upon request.
