SHELL & TWIST® EXCHANGERS
The Barriquand Shell & Twist® exchanger is specially designed to respond to various problems of fouling, thermal program and mechanical fatigue.
IMPACT OF TWISTED TUBES:
- Largely improved internal and external exchange coefficients
- Limited internal fouling of the tubes
- Efficiency of cleaning phases (CIP) optimized
- Reduced mechanical fatigue, the shapes given to the tubes allowing a "bump to bump" contact with a rigid bundle without baffles and without length of unsupported straight tubes.
The speed in the grille is increased, for a better coefficient of exchange outside the tubes.
Thermal equipment, heat exchangers, process equipment, energy recovery.Shell & Twist® twisted tube exchanger Performance gain of 30% on the installed surface (vs a smooth tube exchanger) allowing: - to increase its capacity by installing twisted tube exchangers instead of tubular exchangers. - to improve the hydraulics: Vortex effect limiting clogging at the level of the wall. - to reduce pressure drops on the shell circuit - to eliminate dead zones thanks to the absence of baffles. -> No risk of vibration and significant reduction in the risk of corrosion.
