Alfa Laval WetSurface – Maximum cooling efficiency and lowest possible output

Fri, 26 Jun 2020 08:22:27 GMT

Unlike traditional air-cooled heat exchangers, the tube bundles in a WSAC are sprayed with water and use evaporative cooling to reject the heat from the process medium. This results in superior cooling and a WSAC is both significantly smaller, has a lower power consumption and lower output temperature than an air cooler.

Alfa Laval FlexWater – Enables WSAC operation with low-quality recycled water

Mon, 15 Jun 2020 14:44:55 GMT

Thanks to the spacing between the tubes, the nozzle design and the absence of cooling tower fill, a Niagara wet surface air cooler can operate on water of low quality, e.g. blowdown water from a cooling tower, treated wastewater or sea water.

Effective and efficient cooling with Alfa Laval Niagara wet surface air coolers

Thu, 03 Oct 2019 09:06:29 GMT

The secret behind the effective and efficient cooling in the Alfa Laval Niagara wet surface air cooler systems is our unique WetSurface technology. Thanks to the unique features that we have developed you can keep life cycle cost to a minimum while maximizing cooling performance.

The evaporative cooling process used in Niagara wet surface air coolers is much more effective than the convective heat transfer taking place in a traditional dry air cooler. This means that we can help you cool the process medium more, and the system is significantly smaller and has lower power consumption.

Alfa Laval Niagara wet surface air coolers keep life cycle cost to a minimum...

Thu, 03 Oct 2019 09:06:25 GMT

Find out how the unique features of our Alfa Laval Niagara wet surface air coolers can help you keep life cycle cost to a minimum while maximizing cooling performance. One of these innovations is what we call FlexWater. Thanks to its special design, our systems can operate with water of much lower quality than a cooling tower. The result is much lower fresh water consumption and lower maintenance costs compared to a cooling tower.

All our systems are fully customized to our customers’ requirements, and we can even combine wet and dry operation in one system. We call this HybridCool. These hybrid-systems allow operators to choose operating mode depending on ambient conditions.

Alfa Laval Niagara WSAC: Full cooling capacity cooling systems all year round

Tue, 18 Jun 2019 00:00:00 GMT

Alfa Laval Niagara Wet Surface Air Coolers are custom built, closed-loop cooling and condensing systems that combine high performance, low operating costs, compact size and reliable operation.

When compared to a Cooling-Tower-plus-Heat-Exchanger combination, a Wet Surface Air Cooler can reach much lower outlet temperatures due to its direct evaporative cooling. On top of that, its water-consumption is several times lower and even dirty wastewater streams can be used as spray water.

Compared to a Dry-Air Cooler, the Wet Surface Air Cooler can guarantee you significantly lower outlet temperatures the whole year round, even during the hottest summer months, and this while using a much smaller plot-space and having a much lower power consumption.

Alfa Laval steam heater gasketed plate-and-frame heat exchanger

Wed, 27 Apr 2016 02:00:00 GMT

This animation shows the working principle of an Alfa Laval gasketed plate-and- frame heat exchanger when used as a steam heater. The steam or vapour (illustrated in grey) enters through one of the upper connections and the condensate leaves through the connection underneath. The cold liquid (illustrated in blue transferring into red) enters through one of the lower connections and leaves through the connection above.

As the fluids pass through the heat exchanger heat is transferred from the condensing steam/vapour to the cold media.
The fluids enter through the connections and port holes of the heat transfer plates. Specially designed sealing gaskets located between the plates direct the fluids so that the hot and cold fluids pass counter-currently in alternating channels. When the fluid enters between the plates, it passes over the distribution area. Alfa Laval offers two types of distribution areas: our patented CurveFlowTM and the chocolate pattern. Alfa Laval’s well-designed distribution area is one of the most important features of a plate heat exchanger. Its main purpose is to ensure an even flow of fluid over the entire plate while maximizing heat transfer efficiency and minimizing maldistribution and fouling. In the animation you can see that the distribution area helps the fluids to quickly fill up the entire cross section of the plates.

The animation shows the working principle of a conventional gasketed plate-and-frame heat exchanger, but the same working principle is applicable also to specialized ranges such as our semi-welded and WideGap plate heat exchangers.

Alfa Laval has an extremely broad range of gasketed plate-and-frame heat exchangers which are used in all types of industries. The number of sizes, plate and gasket materials and available options are enormous.
