Plate Heat Exchanger

The Double Wall plate is just as its name indicates,a double plate design.Rather than using single plates between the fluids this design uses double plates to increase safety.The plate pack consists of a set of double plates where each double plate has two identical plates stacked on top of each other and are joined together by laser welds around the ports. A thin air gap between the plates acts as a safety zone in case any one of the two plates were to fail, If any one of the two fluids would leak through the first plate it would be prevented from going any further due to the air gap and the second plate.The leak would show up as a peripheral leak to atmosphere and will be visible from the outside.

Our products are used for cooling marine propulsion engines, generator sets, reduction gears, and auxiliary systems onboard vessels of all sizes worldwide. Each solution is engineered to meet the requirements of your engine, vessel, and operating conditions.

The quailty of your beer is directly affected by how quickly you can cool your wort from boiling to yeast-pitching temperatures. NewRoc Company wort chillers utilize the innovative technology of plate heat exchangers to efficiently chill your wort so that you can expect clarity in your beer without the fear of affecting your brew's flavors.

The requirements of heat exchangers are as diverse as their applications - this is why nine out of ten heat exchangers we deliver, are customized to our clients' needs.
Being with you, we develop innovative heat exchanger concepts that clearly set you apart from other manufacturers in terms of efficiency, compact design and service life: from customized fittings for optimum installation through to the complete heat exchanger design in the material that best suits your application.
Depending on your requirements regarding corrosion resistance, thermal conductivity as well as mechanical and processing properties, we choose the most suitable material.

Cross Flow Plate Heat Exchangers accommodate viscous fluids or those containing fibrous materials or larger particles. Wide-channeled horizontal ribbed pattern with no metal-to-metal contact allows Cross Flow of particles that can block other heat exchangers.
In many ways, Cross Flow Heat Exchangers are similar in function to conventional plate heat exchangers.
However, their distinctive engineering and construction makes them ideal for specialized applications. They are used in pulp and paper production; processing of beet sugar; beer mash processing at breweries; and sludge processing, which includes a gamut of applications such as quenching oil, plating solutions, and work with crystals. Food processors use free-flow heat exchangers for heating and cooling in grain processing. The units are also used in producing ethanol and in textile mills.

Heat exchangers are the essential parts for pulp & paper mills. With the help of heat exchangers, paper mills benefits a lot either in energy saving or environment protecting.
One part of the paper machine also uses a type of heat exchanger known as a waste heat recovery system, which is one of the ways that heat exchangers are able to save energy, resources and money for a paper mill.

NewRoc have many years experience in the application of plate heat exchangers, has proposed a variety of heat exchange schemes for closed-loop circulating water systems, oil cooling systems, heat recovery systems for power plants. The best use of energy is to improve the efficiency of power plant.

The plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change.

Both space and weight are at a premium on offshore oil platforms, hence filtration techniques making use of smaller and light-weight apparatus are of particular interest to this industry. Crossflow plate heat exchanger has these advatages over deep bed and cartridge filtration. Other usese for filtered seawater include desalination and cooling water duties, where the required flows are also large.
