WeldPack® Welded Plate Heat Exchangers

Welded Heat Exchanger in the Dairy Processes

A Welded Plate Heat Exchanger is very efficient for energy usage in milk pasteurisation. During pasteurisation milk is heated to a high temperature and then quickly cooled before bottling or packaging to keep it fresh for longer. This process makes the milk safer to drink by killing the bacteria.

Usually pasteurisation units are used where the product is heated to a pasteurisation temperature, goes out into holding tubes, and then re-enters the Welded Heat Exchanger to be cooled down again for bottling. Heating and cooling inside the same heat exchanger results in a maximum  amount of energy recovery.

There are 3 phases to the process:

1: Heat recovery –  cold product enters the Welded PLate HEat Exchanger, is pre-heated by the already heated product before returning to be cooled.

2: Pasteurisation – preheated product from the heat recovery phase is then heated by water to the pasteurisation temperature.

3: Pre-cooled product from the heat recovery phase is then cooled down to a desired final outlet temperature.

Because of our frame design we are not limited to connections at the front and back of the unit but instead can take product in and out in the middle of the plate pack.

Welded Heat Exchanger Server Rooms

Due to the nature of Server Rooms and Data Centres, they produce large amounts of heat. Because they produce large amounts of heat, energy hungry units are often installed to cool the area down to the desired operating temperature. Installing a Welded Plate Heat Exchanger solution can provide provide year-round cooling, while also focusing on efficiency and decreasing your annual running costs.

When a space is cooled down using refrigerant, the warmth from the room needs to be exhausted away – usually atmosphere. 

With a Welded Plate Heat Exchanger system you can capture this wasted heat and utilise it elsewhere in the building e.g. hot water or comfort heat other rooms.

A Welded Plate Heat Exchanger can minimize the need for traditional mechanical cooling. You will reduce your power bill and the environmental impact with unique solutions that maximize efficiency for minimized energy consumption.

A Welded Plate Heat Exchanger can boost sustainability by taking advantage of free cooling as well as heat recovery opportunities.

Welded Heat Plate Exchanger in the Sugar Refinery Process

The production of sugar from cane or beets is an energy-intensive industrial process of extraction, purification, evaporation and crystallization. By product recovery via methanisation and cogeneration is a major objective.

Sugar factories strictly follow the cane or beet production cycles. Plant operation is continuous, requiring reliable technologies as production shutdowns are often impossible. The Welded Plate Heat Exchanger greatly assists with these needs.

The juices extracted at ambient temperature must be heated through purification stages up to evaporation, requiring Welded Plate Heat Exchangers.

Heating juices before clarification require a Welded Heat Exchanger. Clear or thin juices are heated via high energy vapor and the Welded Heat Exchanger reduces unit voluminosity and installation costs.

The syrup from crystallization are mostly particle free fluids however during remelt of the syrups, clumps produced and therefore the Welded Plate HEat Exchanger should be the first choice.

Welded Heat Exchanger in the Vegetable Oil Refinery Process

Due to the nature of the oil refining process, a Welded Heat Exchanger is used for the various temperature and pressure requirements of this process as explained:

In the process of oil production, the seeds are hydrolyzed by the enzymes of the seed, forming some sulfur-containing compounds and other toxic components.This affects the quality of the oil. The general smelting process has a very low removal rate of sulfides. Therefore, edible oil should be refined with the help of a Welded Plate Heat Exchanger.

Alkali refining operates at a initial temperature of 30~35 °C, final temperature 60 ~ 65 °C. Decolorization via vacuum dehydration for 30 min, under temperature 90 °C, absolute pressure 4.0 kPa.  The decolorization temp is 90～95 °C, then cooled down to below 70 °C to filter. The decolorized filter oil is heated to 100 °C by a vacuum suction deodorization tank.

The deodorization temperature is not lower than 245 °C, and the absolute pressure is 260-650 Pa. The atmospheric condenser water temperature is controlled at about 30 °C, and the stripping direct steam pressure is 0.2 MPa.  After the deodorization is completed, it is cooled to 70 °C and filtered.

Welded Plate Heat Exchanger in the Waste Water Process

The Welded Plate Heat Exchanger helps reduce the environmental footprint from water and waste streams, by maximizing reuse of water, by turning waste to value. It also minimizes energy consumption and waste. It lowers the total operating costs. Maximizes resource reuse. Reduces energy usage, polymer consumption and disposal costs. It increases capacity and reduces installation and start-up costs.

Cost savings, reduced environmental impact and new income streams from recovered resources are the future. Every wastewater treatment plant is unique and has its own set of challenges and opportunities. With our expertise in processing and our broad range of products, we can support your shift to a circular resource flow. Regardless of whether you are a contractor, designer or plant operator we can help you find the optimum solution for your specific project.
