Frese A/S

Frese A/S is a leading manufacturer of high-quality valves for marine, industrial and HVAC market segments globally. The extensive product portfolio ranges from ball and butterfly valves, 3-way valves to the core-technology; pressure independent balancing and control valves. Frese’s ability to adapt our technology to meet the demands of the marine sector, where it must perform flawlessly in the most arduous environments, stems from our extensive knowledge of materials, products and applications, which we have built up over 75 years. Over the years we have expanded our portfolio to include our well-tested technology in new materials, such as nickel-aluminum bronze and high-grade stainless steel in order to meet the marine industry’s demands for highly corrosion resistant materials. At Frese we pride ourselves on being more than a supplier of high-quality products – we are a reliable partner and trusted advisor who can help you build your business case for a transition from static to dynamic valves and by doing so achieve significant energy savings. Benefits of PICV technology Frese’s patented pressure independent technology is an innovative, energy saving alternative to traditional hydronic balancing and control methods, and it provides efficient and accurate flow and differential pressure control. By being pressure independent, the valves ensure that design flow conditions are achieved at all times, irrespective of pressure fluctuations in the system, and also eliminate overflows in the system – resulting in significant pump energy savings. Dynamic valves hold several other advantages over traditional, static balancing valves. They contribute to simplified system designs by eliminating the need for additional balancing valves in the distribution pipework and are highly flexible if your system needs to be modified or expanded at a later date. Pressure independent control valves are also much easier to commission since they require no proportional balancing. They automatically adapt to any changes in the rest of the system. A case study of Frese by Odense Maritime Technology A/S estimates reductions of 50% to 80% in commissioning hours related to the fact that with the Frese valves you can do the commissioning work unit by unit or zone by zone without interference from pressure fluctuations from other consumers. Retrofit While it is possible to integrate PICV technology in new builds, there is also a huge untapped potential in retrofitting Frese valves into the existing cruise and ferry fleet. The retrofit itself requires no changes to the pipework and only a small addition to the pumps in the form of variable frequency drives to establish control. Other than that, it is simply a matter of exchanging the required valves for dynamic Frese valves. If the vessel currently operates 3-way valves, savings of more than 50% can be expected, while replacing static 2-way valves will bring savings of above 40%. However, the most significant savings can be found below deck where cooling systems with no flow control are very common. By optimizing here, we have generally seen customers realize savings of up to 70%. Frese A/S is part of the family owned Frese Group, which was first established in 1944. The company develops and manufactures dynamic valve technology and other innovative flow control solutions for HVAC systems as well as Marine, Industry and District Energy market segments all over the world. The Frese Group also operates its own Metal & Steel Foundry, specializing in customized sand-casting solutions for the most demanding applications. Frese takes responsibility for future climate efforts and the green transition and does so with a solid focus on energy optimization and sustainability. With its headquarters and main factory located in Slagelse, Denmark, production facilities in UK and China and a sales organization spanning the globe, The Frese Group employs 250 people. Test only
