Alfa Laval spiral heat exchangers are designed to handle the toughest heat transfer challenges. Whether it’s frequent fouling from dirty media, or limitations from pressure drop and floor space, they are the ultimate problem solver for liquid-to-liquid and two-phase duties. The robust, efficient and compact designs keep both installation and maintenance costs extremely low, and they have a proven reputation for almost never fouling up.
Alfa Laval spiral heat exchangers are circular units containing two concentric spiral flow channels, one for each fluid. The different media flow counter currently: one fluid enters the centre of the unit and flows towards the periphery, the other enters the unit at the periphery and moves towards the centre. The channels are curved and have a uniform cross section. There is no risk of intermixing.
The product channel is normally open on one side and closed on the other. The channel for the heating/cooling medium can sometimes be closed on both sides, depending on the cleanliness of the heating/cooling medium. Each channel has one connection in the centre and one on the periphery of the heat exchanger
- 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
- Each unit is fully customized, offering the best thermal fit for the specific duty
