Alfa Laval – spiral heat exchangers The all-round heat transfer solution
Open the catalog to page 1Spiral-shaped heat exchangers are not a new idea – but Alfa Laval has perfected the design. Exceptional compactness and self-cleaning design make Alfa Laval spiral heat exchangers extremely versatile. Ideal for everything from dirty fluids to high vacuum condensation.
Open the catalog to page 2Product ranges We provide fixed-size and customized product ranges to meet the needs of our customers. Fixed-size ranges We make small units for general use, and for application-specific purposes such as the wastewater industry. Customized range To meet requirements for a range of sizes and specifications, the majority of the spiral heat exchangers we supply are individually customized. 4 Alfa Laval – spiral heat exchangers The idea of using spiral-shaped fluid channels for heat transfer arose in response to a particular customer’s process problem. Other technologies had failed, but in this...
Open the catalog to page 4Alfa Laval – spiral heat exchangers 5 Heat exchange duties that benefit from the strengths of spiral heat exchangers include: liquid/liquid heating, cooling or heat recovery, where one or both of the fluids may cause fouling. vapour/liquid condensing, particularly at very low pressure and/or highvolume flow. The design, shape and size of the spiral channels can be customized so that they are a perfect match for the demands associated with a wide range of process fluids, thermal duties and industrial applications. Strong on customized solutions The spiral heat exchanger is a very versatile...
Open the catalog to page 5Some customers choose spiral heat exchangers to boost the performance of their existing processes. Others use them for thermal duties in processes that would otherwise simply be impossible. Whether replacing existing “inefficient” technology or being used in revolutionary new applications, spiral heat exchangers are the first choice for processes that involve demanding liquid/liquid duties. The self-cleaning heat exchanger for demanding liquid/liquid duties Single channel technology makes keeping clean easier Single channel technology – what goes in must come out As the name indicates,...
Open the catalog to page 6Alfa Laval – spiral heat exchangers 7 Easy access When processes involve fluids that are capable of causing a high degree of fouling, it is important to have easy access to the inside of the heat exchanger for cleaning and inspection. Compared with other types of heat exchanger, spiral units provide the best access to their heat transfer area – with no special tools or lifting equipment required. Each fluid channel is easily accessed via its cover, exposing the whole of the heat transfer surface. Two covers enable one or two fouling fluids Both hot and cold channels are designed to...
Open the catalog to page 7One of the best examples of the flexibility of a spiral heat exchanger is its capability as a condenser. Different condensing duties place different demands on a heat exchanger. The desired condensing performance is achieved by determining the flow path of the vapour. Alfa Laval spiral condensers perfectly complement Alfa Laval’s other process condensers – the AlfaCond and the Compabloc – to provide customers with a full range of condensers for the entire range of their processes and applications. The customized condenser The versatility of spiral heat exchangers makes them ideal for...
Open the catalog to page 8Coolant Coolant Vapour from column Condensate Inert gas Two units in one – cross-flow and counter-current paths in the same unit The flexible flow-path arrangement and installation possibilities provided by spiral heat exchangers give them important advantages compared with other condensing solutions. Two heat exchange duties can be performed within a single spiral to further reduce capital equipment costs, and to maximize operating efficiency. For example, a spiral heat exchanger can act as a condenser and sub-cooler for condensate and/or inert gases, or as a pre-heater to remove...
