We are the best Plate Heat Exchanger suppliers in Qatar

Our company is in the business of delivering customized, future-proofed PHE technology which not only streamlines processes and saves on energy, but also provides clients around the world with quantifiable cost reductions, particularly in difficult conditions. We develop PHEs that are able to work under the harsh operating conditions and elevated thermal loads of the large-scale power generation and refinery plants in Qatar.

What is Plate Heat Exchanger?

A Plate Heat Exchanger (PHE) is a small apparatus that is utilized in the transfer of heat between two liquids in an efficient way without combining the two liquids. It is made up of a row of corrugated metal plates that are squashed to each other, forming several corridors, in which the fluids move in opposite directions. The design has the highest surface area of heating and cooling, which makes it highly thermal-performing with a minimum footprint.

Types of Plate Heat Exchanger

Being as premier Plate Heat Exchanger manufacturers in Qatar, according method we provided different types which are given below.

By sealing method

Gasketed Plate Heat Exchanger: It involves the use of gaskets to enclose the plates and ease dismantling during the maintenance process and cleaning. Plate Heat Exchanger suppliers in Qatar can be extended by adding or taking away plates providing the modular design.
Brazed Plate Heat Exchanger: The plates are permanently brazed and this gives a rigid and compact system. This is a one-piece and not type and in case one plate is damaged, the unit will have to be changed as well.
Welded Plate Heat Exchanger: maximum stability and reliability are provided by welding the plates together. The semi-welded variety is a variation, where the aggressive fluid side is welded and the other is gasketed.

Other types and variations

Plate and Frame Heat exchanger: This term denotes the gasketed type, which is used to refer to the frame containing the gasketed plates.
Plate and Block Heat Exchanger: It is a small-sized design, and the plates are welded together for Plate Heat Exchanger exporters in Qatar.
Plate and Shell Heat Exchanger: This is a hybrid of a plate heat exchanger inside a shell, which is compact and has pressure resistance.

Benefits of Plate Heat Exchanger

We as Plate Heat Exchanger suppliers in Qatar, we provided different benefits which are given below.

Huge Thermal Efficiency: The corrugated plate design generates tremendous turbulence and a huge heat transfer surface with temperature approach differences of as low as 1degC for Plate Type Heat Exchanger.
Small Size: They do not need much space on the floor as compared to shell and tube units to perform the same task, so they are suitable to industrial sites with limited space or on offshore platforms for Plate Heat Exchanger manufacturers in Qatar.
Easy Cleaning and Services: The plate can be easily separated using the bolt frame to clean the machine and this makes it easy to maintain and saves time in servicing it.
Modular Capacity: PHEs are easily adjustable to new demands, by adding or removing plates to the frame, making it easy to add capacity or reduce capacity in future.
Reduced Fouling Tendency: The plate pattern creates high fluid turmoil that is useful in scrubbing the heat transfer surface, which retards the accumulation of the fouling material in K-PEX Plate Heat Exchanger.

Applications of Plate Heat Exchanger

We serve as premier Plate Heat Exchanger exporters in Qatar, it is applicable in different sites which are given below.

HVAC and District Cooling: Are implemented to provide central connection between the chilled water circuit and the plant circuit to avoid contamination of water and also to safeguard the delicate equipment for Plate Heat Exchanger manufacturers in Qatar.
Oil and Gas Industry: Oil and gas are needed to cool engine jackets water and lubricating oil in generators and compressors, to make sure that machinery does not overheat.
Marine and Seawater Cooling: Plate Type Heat Exchangers is used in central cooling systems in ships that utilize corrosive seawater as the secondary fluid and seed corrosion is reduced to onboard machine parts.
Food and Beverage Pasteurization: Pasteurizers use it to provide a quick heating and cooling process to liquids, such as milk or juice which eliminate any pathogens and maintain the quality and nutrient content of the product.
Power Generation: Utilized in power plant auxiliary cooling loops and it is an efficient way of dissipating heat in closed systems by means of cooling towers or other water bodies.

(FAQs)

A: The gasket life varies depending on the type of fluid and temperature, with an average of 3-10 years, thus they have to be replaced during normal full unit service.

A: They typically work best with clean fluids, although specially designed PHEs with broader gap plates are used to work with those fluids that have low levels of fibers or particles.

A: The most common are Stainless steel (SS304/316) which is used in general purposes and Titanium or high-nickel alloy which is very expensive to use but it is intended to deal with very aggressive or corrosive chemicals.
