Filtration
Alfa Laval is the world leader in technologies for the mechanical separation of liquids. Alfa Laval is committed to develop our portfolio of filtration products in line with our goal to optimise the performance of your processes time and time again.
Separation and protection
Filtration technology from Alfa Laval range from the separation of valuable materials at a level of microns, to filtering out unwanted marine life from plate heat exchangers, to protecting fuel and lube oil systems from engine or other debris.
It’s all about size
Cross flow membrane filtration is one of the corner stones of Alfa Laval’s filtration technology because of the unique selectivity of the separation technique. Cross flow membrane filtration is a growing technology within Alfa Laval.
Filters and strainers
Filtration technology to filter or strain particles from fluid passed through a process can take a variety of methods and forms. Alfa Laval has developed and perfected a number of unique filtration and strainer technologies that will optimise the performance of your processes.
Filters for oil, water, sludge and more
For many applications Alfa Laval has developed a host of filter or strainer based solutions for the efficient removal and retention of solid/foreign material from flowing liquids, in order to keep your downtime to a minimum, by preventative protection.
The Moatti range of automatic and manual filters for fuel oil and lubricating oil are recognized as the number one filtration technology for large engines.
For protecting cooling equipment, filters such as ALF – the Alfa Laval Filter, can be used to take debris and marine life from low grade water, increasingly being use for major cooling systems. The Alfa Laval Filter is also a versatile filter for other cooling media.
For sludge thickening the ALDRUM drum thickener is a rotating drum filter that handles sludge extremely gently and gives exceptionally high recovery for nearly all sludge types.
Pushing the boundaries of Filtration
By combining a number of filtration and separation technologies Alfa Laval continues to push the boundaries of filtration solutions for many process industries. The Confilt and W-SIL systems combine hydrocyclone technology with dynamic cake removal to separate particles down to 10µm.
HEAT TRANSFER
Heating and cooling are essential parts of most industrial processes. The demand is for these applications to be carried out with the least energy consumption. Heat exchangers provide an efficient technology for heating and cooling.
Heat exchangers exist in many forms, and as one of the world's leading companies in this field, Alfa Laval naturally has a full range:
Plate heat exchangers
Alfa Laval - choose a market leader: Alfa Laval is the leading manufacturer of plate heat exchangers in the world. We provide you with compact, modern solutions with the highest thermal efficiency.
Similar on the outside, unique on the inside
All plate heat exchangers look similar on the outside. The difference lies inside, in the details of plate design and the sealing technologies used. Alfa Laval is in the forefront of R&D work on plate heat exchangers. We continue to improve and develop products to optimise our customers processes. Time and time again.
Plate heat exchangers from Alfa Laval are available as:
-
Copper & nickel brazed
- Evaporators & condensers
- Fully welded
- Fusion bonded
- Gasket
- Semi welded
Purpose built systems
The application of purpose built systems for a particular purpose or end product such as vegetable oil or fresh water is one of Alfa Laval’s key competencies. Our customers rely on this expertise when thermal economy is a premium consideration.
Alfa Laval’s purpose built systems include, fresh water generators and the SoftColumn deodorizer:
- Fresh water generators
- Deodorizing systems
Scraped surface heat exchangers
Scraped surface heat exchangers consist of a cylinder that that has an inner tuber (heat transfer surface area) and an outer tube. Between the two tubes, there is annular space, where the heating or cooling media flows counter-current to the product. Inside the inner tube, a bladed shaft rotates and removes the product from the heat transfer wall areas.
Alfa Laval has a selection of scraped surface tubular heat exchangers (SSTHE):
- ViscoLine Dynamic (new range)
- Contherm (extended range)
Tubular heat exchangers
Alfa Laval is mostly known for its expertise within plate heat exchange technology. However, we also offer a wide range of high quality tubular heat exchangers for various applications. Our tubular heat exchangers are:
Spiral heat exchangers
Spiral Heat Exchangers exhibit ideal heat transfer and fluid handling characteristics for a wide range of applications within sludge treatment.
Compared to a traditional sludge treatment heat exchanger a spiral heat exchanger:
- Takes up only one sixth of the space
- Means lower costs for buildings, pumps valves and piping
- Uses 75% less pumping energy
- Provides higher K- value and a close temperature approach
- Ensures continual self-cleaning
- effect for maximum operating efficiency
