Well-designed and long service life

Alfa Laval AlfaQ™ gasketed plate-and-frame heat exchangers are available to meet most heat transfer requirements – whether large or small – demonstrating our commitment to optimizing the performance of our customers’ processes.  

Equipped with well-designed features the heat exchangers are easy to maintain and have a long service life. Some of the features available include:

• ClipGrip™ gasket – a glue free gasket with superior alignment that ensures a perfect seal and trouble-free maintenance.
• Glued gasket – a two-component, oven-cured epoxy glue that keeps the gasket in place during any possible cleaning condition.
• CurveFlow™ distribution area – ensures full use of the heat transfer area and minimizes fouling.

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.

AlfaQ™ is quick and easy to modify if process parameters change. Our team’s expertise and the availability of parts bring you peace of mind.

Plate types for different needs

AlfaQ™ is available with two different plate configurations:

• Single plate with a chevron pattern design for parallel flow allowing for optimum thermal performance and pressure drop.
• Single plate with a chevron pattern design for diagonal flow through the heat exchanger when it is mounted horizontally and requires draining.

Versatile design

The Industrial line’s versatility allows it to be designed and configured for applications ranging from relatively simple duties with low requirements to very demanding duties with the highest requirements on both performance and documentation. The products are used for heating, cooling, heat recovery, condensation, and evaporation.

Plate types for different needs

Industrial line is available with four different plate configurations:

• Single plate with a chevron pattern design for parallel flow allows for optimum thermal performance and pressure drop.
• Single plate with a chevron pattern design for diagonal flow allows for optimum thermal performance through the heat exchanger when it is mounted horizontally and requires complete drainability.
• Double wall plate is used when extra care is needed to avoid mixing fluids.
• Gemini double wall plate is used when extra care is needed to avoid mixing fluids in hygienic applications.

The thin, corrugated stainless steel plates used in the CB design are brazed together with copper. This forms a self-contained unit that can handle both high pressures and high temperatures. And unlike traditional designs, the brazed plate heat exchanger consists solely of surfaces that actively contribute to heat transfer, resulting in significant increases in overall efficiency.

The CB range of brazed plate heat exchangers has numerous advantages over traditional heat exchangers in both industrial, HVAC and refrigeration installations. The exceptional heat transfer efficiency makes all CB units very compact. As a result, they can tackle large-capacity duties even though there is only limited installation space available.

The brazed construction also does away with gaskets, making CB units ideal in applications where temperatures and/or pressures are high. Examples include district heating and a wide range of heating, cooling and tap water solutions.

Alfa Laval is the world's leading manufacturer of brazed plate heat exchangers. This means solid experience in designing units that withstand high-pressure and high-temperature conditions, and in coping effectively with the structural stresses that results from these. Units in the CB range are available in many different sizes and capacities, with varying plate patterns and connections for particular duties and performance specifications. CB units can be configured as single-pass, dual-pass or multi-pass installations, according to project requirements.

Alfa Laval AlfaNova plate heat exchangers are made of 100% stainless steel, with the components fused together using a breakthrough technology that Alfa Laval has patented. This provides levels of hygiene and corrosion resistance unmatched by any other brazed heat exchanger. It also makes it practical to use stainless steel plate heat exchangers in installations normally reserved for conventional semi-welded and welded units.

With the Alfa Laval AlfaNova, it becomes feasible to use a high-efficiency plate heat exchanger under the kinds of extreme temperature and pressure fatigue conditions that would probably destroy a conventional brazed heat exchanger. As a result, AlfaNova units have become a breakthrough gasket-free alternative for a wide range of industrial applications that use aggressive liquids and in which there is a need for high-efficiency, hermetically sealed plate heat exchangers that ensure low life cycle costs even under high-temperature conditions. The 100% stainless steel construction makes it possible to withstand temperatures of up to 550°C (1,020°F).

To guarantee maximum safety, reliability and durability, Alfa Laval AlfaNova units have been subjected to exhaustive testing focusing on pressure fatigue, thermal fatigue and corrosion resistance. Such dependability, along with the other multiple benefits of this innovative design, make AlfaNova a cost-effective heat transfer solution in a wide range of duties. Examples include systems using refrigerants such as ammonia, while its resistance to corrosion also makes Alfa Laval AlfaNova popular in district heating installations in which corrosive water is used.

The hygienic heat transfer channels and mechanical strength also make Alfa Laval AlfaNova units ideal in applications where the prime focus is on hygiene, such as clean water refrigeration chillers and tap water heating systems.
