Improving sustainability with Alfa Laval’s spiral heat exchangers
Minimal fouling, or clogging, in duties involving very dirty, highly viscous or particulate media, ensures uptime
Easy-to-open design makes cleaning quick and simple, ensuring low maintenance costs
Reduced pipework and steel structures means lower installation costs
Increased energy savings and reduced emissions thanks to thermal efficiencies 2-3 times higher than comparable shell-and tube exchangers
WASTE HEAT RECOVERY
The secret is the true counter-current flow. It enables crossing temperature situations where the cold fluid can be heated to temperatures very close to those of the hot fluid.
The closer the temperature approach between two fluids, the more heat is recovered.
This effect is enhanced by the high turbulence in the unit due to the single channel geometry and the arrangement of the studs.
Dead spots eliminated
The single-channel geometry and stud arrangement offer other important benefits as well.
The fluid is fully turbulent at a much lower velocity than in straight tube heat exchangers, and each fluid travels at constant velocity
throughout the whole unit.
This eliminates the risk of dead spots and stagnation.
