Heat Exchanger (Alfa Laval)


The heat exchanger represent the best available performance of liquid/liquid and liquid/steam applications. The heat exchanger is of a very compact design and without welding, which makes it very easy to disassemble and assemble when maintenance is required. The internal liquid volume is very small which provide excellent temperature control in the heat exchanger. The thickness of the heat exchanging plate, which separate the two liquids, are only 0.4mm – 0.8mm providing low manufacturing cost even for high grade materials such as titanium and nickel alloy. If the liquid specification will change, modifying the heat exchanger is easily done by replacing the heat exchanging plates.
For gasket plate type heat exchanger, the lifetime of the elastomer used for sealing the liquid inside the heat exchanger, are dependent on the selected elastomer material, liquid type and material temperature resistance.

Plate Type Heat Exchanger

Alfa Laval is the world largest manufacturer of plate heat exchanger and have for many years continuously being developing plate heat exchangers for a variety of applications.
Depending on the required fluid, pressure and temperature range, each plate heat exchanger will individually be designed with the applicable plate material and gasket material.
The main plate materials are stainless steel (SUS316), titanium, high nickel alloys and graphite. Main gasket materials are NBR, EPDM and FPM (FKM)
The various plate type heat exchangers are also available as evaporator, condenser and can also be used for liquid sludge applications, distiller and other special applications.
Welded type plate type heat exchanger (Compabloc)

The Compabloc is a breakthrough plate heat exchanger design that combines a whole range of technological advantages into one compact unit. The all-welded plate pack does away with all gaskets between plates, and makes it possible to operate with a wide range of aggressive media and at high temperatures and pressures.
Corrugated plate patterns generate high turbulence that results in overall heat transfer coefficients three to five times greater than a shell-and-tube heat exchanger. In addition to minimizing fouling, this makes it financially viable to use corrosion-resistant exotic metals
The Compabloc frame consists of four corner girders, top and bottom heads and four side panels with nozzle connections. These components are bolted together and can be quickly taken apart for inspection, service or cleaning.
Main plate material: SUS316L, Ti, nickel alloy
