launched new rotary scraped surface heat exchanger. Known as the HRS Rotex, it is the latest innovation from the company’s product development centre in Lorquí, Spain.


The patent pending device is said by HRS to have a number of key features that make it stand out from other rotary scraped surface heat exchanger technologies. For example, it combines a high heat transfer capacity with increased surface area. This, together with its helical screw, reduces pumping costs and makes it a good solution for highly viscous products.


An added bonus, says the company, is ease of maintenance; designed into the product, this reduces operational costs and makes the HRS Rotex an ideal solution for both new projects and to replace existing equipment where energy savings and whole life costs are key in the decision making process.


The brazed plate heat exchanger (BPHE) is one of the most efficient ways to transfer heat from one medium to another. A BPHE consists of corrugated plates combined to create complex channels through which a hot medium and a cold medium can be distributed. The media come into close proximity inside the BPHE without mixing on either side of the corrugated plate, and energy is

transferred from one to the other as they flow side-by-side.


Using its AsyMatrix technology, SWEP’s heat exchangers are designed to deliver maximum energy efficiency and system performance.


The company’s B633 is built on its novel XXL platform, with six-inch ports and high plate numbers. It handles water flows up to 350m3


/h with a pressure drop limited


to 50kPa. This high flow capacity BPHE is suitable for a diversity of demanding applications, such as condenser and evaporator in power generation, engine oil cooler, steam condenser, heat recovery in chillers, or for specific district heating installations.


The product offers plate heat exchanger- like capacities at high temperature and pressure, without the wear and tear of parts. Up to 95% of the material in BPHEs is used to transfer heat, as opposed to other technologies that use much of their material for support equipment, shell or frames.


In business news, heat-transfer technology and engineering and design services specialist Luvata has moved into a new, larger facility at its heat exchanger manufacturing facility in Juarez, Mexico. It has doubled the space of the company’s existing facility (Fig. 1). l


Triton fund buys GEA heat exchanger business


he Triton fund has agreed to buy GEA Group’s heat


exchangers business for approximately €1.3 billion. The business is an important global manufacturer of heat exchanger products. GEA’s diversified product line and application portfolio includes wet and dry cooling


systems and components and other project-type businesses. The company is based in Bochum, Germany and employs 7,300 people worldwide. Its 2013 revenues were €1.5 billion. “GEA Heat Exchangers operates in niche markets with global growth opportunities. Triton looks


forward to supporting the management team in developing the company further as a standalone entity,” said Peder Prahl, director of the general partner of the Triton funds. In Europe, the Triton fund focuses on companies in industry, health and business services. l
