AlfaVap

Unique design for thermal efficiency

Alfa Laval’s AlfaVap unique design provides higher thermal efficiency than the traditional shell-and-tube evaporators and because of this much less heat transfer area is needed. AlfaVap heat exchangers are cost-efficient especially when exotic metal materials are required.

AlfaVap’s advantage is that they work also when the temperature differential between the hot and cold fluids approaches as low as 2.5°C (4.5°F) meaning that lower grade steam and more effects in series can be use in an evaporation system compared to the shell-and-tube systems. This saves steam costs.

Compact design and versatility

The compact design and versatility of the AlfaVap means that they are cost-efficient and easily installed even at high elevations.

AlfaVap heat exchangers are easily accessible for inspection and mechanical cleaning by removing the tightening bolts and rolling back the pressure plate.  For Cleaning-in-Place (CIP), only a small amount of cleaning chemicals is needed because of their low hold-up volume.

AlfaVap’s design makes it easy to adjust evaporation capacity to meet changing needs by adding or removing plates to the existing frame. This is a major advantage over shell-and-tube units where the capacity cannot be changed once it’s installed.

Equipped with well-designed features, the AlfaVap heat exchangers are easy to maintain and have a long service life. They feature a clip-on gasket which is a glue free gasket that ensures perfect sealing and trouble-free maintenance.  Additionally, the pressure plate roller, the bearing boxes on tightening bolts, and the 5 point alignment system with reinforced hangers make opening and closing the heat exchanger quick and easy without the need for heavy tools or the risk of damaging the plates.
