Features

Alfa Laval’s experience of over 80 years in heat transfer innovations makes them the best at understanding what it takes to deliver high-performance solutions for any applications. Some of the features highlighted are; 

• PressureSecure – the innovative plate designs support the widest range of high-temperature and high-pressure applications. Units can run using thinner plates and fewer plates, which translates to less raw material, low energy consumption, reduced refrigerant charge and a longer equipment lifecycle. 
• FlexFlow™ – Alfa Laval’s patented asymmetrical plate design is one of the many unique innovations that showcases the improved thermal efficiency due to the optimized pressure drop and increased turbulence. With this technology, the AlfaNova is able to cut energy consumption, reduce refrigerant volumes and raw materials. 
• AlfaNova® – it is 100% stainless steel, AlfaNova is a solution that Alfa Laval offers for applications that use media not compatible with traditional heat exchanger materials. Not only is this advanced design optimized for natural refrigerants, it is also completely recyclable. 

Two media at different temperatures flow on either side of the thin corrugated stainless steel plates that are stacked on top of each other. The two media flow in a countercurrent flow through alternate channels and are held within the plate pack by a fusion-bonded seal around the edge of the plates are in contact with each other are also bonded with the same technology, reinforcing the pack against the pressure of the media inside. 

The countercurrent flow makes it possible to extract heat efficiently even when there are only extremely small differences between the temperatures of the hot and cold media. This results in notable energy cost savings. 

Application 

Suitable for a wide range of applications, such as ; 

• HVAC heating and cooling 
• Refrigeration 
• Oil Cooling 
• Industrial heating and cooling 
• Process heating and cooling 

Design 

The AlfaFusion filler material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. Using advanced design technologies and extensive verification guarantees the highest performance and longest possible service life. 

The brazed design holds the plate pack together internally with contact points, doing away with any need for external plate frames at design pressures up to 70 bar/1015 psi. Distributing hte load across many separate contact points provides excellent resistance to pressure fatigue. The materials of construction are made of the same material, making it thermally efficient as well as being shock-proof and having a mechanical strength fully equivalent to any welded counterpart. 

Based on standard components and a modular concept, each unit is custom-built to meet the specific requirements of each individual installation.
