Tube-in-tube Heat Exchangers Features
Tube-in-tube heat exchanger (also known as double tube heat exchanger) consists of a heat exchanger with two concentric tubes. The product flows through the inner tube while the service does it through the space between the two tubes.
Tube-in-tube heat exchangers, or double-tube heat exchangers, are specially designed for heating or cooling products with low-medium viscosity. The great advantage of Tube-in-tube heat exchangers is to be able to process products with fibers or particles, without the risk of clogging.
A Tube-in-tube heat exchanger can achieve a pure countercurrent flow, which allows a temperature crossover to be achieved, so that the cold fluid can be heated above the hot fluid outlet temperature.
The use of flanged connections allows these tubular heat exchangers to be disassembled to facilitate cleaning and maintenance tasks.
