Your application. Your Vario! Millions of types but only 1 parameter that counts: You. Once your requirements have been fed into our tried-and-tested Güntner Product Configurator (GPC), it will dynamically design your individual unit. The process is fast and reliable and is based precisely on the application that you have in mind. With pinpoint accuracy. The wide modular variety of heat exchanger coils, casing types, fans and accessories is what allows the GPC to come up with such a perfectly tailored design. A playground for all your ideas Whether you are looking for a condenser, gas cooler or fluid cooler, you will always find the perfect solution to meet your specific needs with our Vario units plus our extensive range of accessories. Optimised key component The extensive, modular heat exchanger concept with numerous tube geometries and optimised tube circuiting allows for precise designs plus special designs offered as standard solutions. Vario The Vario product line comprises series which can be customised quickly and accurately for individual projects by means of the Güntner Product Configurator. Customers can select the configuration that best suits their individual requirements from a variety of different material combinations, variants and accessories. Unbelievable energy efficiency High-quality fans paired with Güntner's sophisticated control concepts produce unbelievably energy-efficient units. Plus calculation directly at the operating point and certification. Tailor-made fit for the key component Your heat exchanger coil is protected by a robust and durable casing which is easy to transport plus colour varnish of your choice 2 3
What sets your Güntner Vario apart? Certified capacity specifications As part of the certification process, all series of a participating manufacturer are tested and approved by specially authorised laboratories. With units with the Eurovent certification seal of approval you can rest assured that the specified performance values and low noise levels are actually achieved. Versatile Condensers for synthetic refrigerants, hydrocarbons and ammonia Gas coolers for transcritical CO 2 systems Fluid coolers for water/glycol mixtures Oil coolers for process and machine cooling Reliable and leak-proof Tried-and-tested Güntner floating coil principle (the fluid-carrying tubes do not have any contact with the casing, which increases the service life of your heat exchanger) High degree of torsional resistance on account of profiled side plate (Güntner profile) when transported by crane or fork-lift truck Snow/wind loads taken into account statically Unbelievable energy efficiency AC/EC technology ErP-ready Calculation of sound power directly at the operating point Control concepts adapted specially for the unit Ideal measurements Low transport costs on account of optimised unit dimensions for truck and container transport Specially optimised module sizes for high flow rates, minimal tube volumes and all capacity ranges Control with added value Stable operations in particularly low partial load ranges Low Capacity Motor Management (LCMM) Continuous cooling emergency operation function in the event of control signal failure Reliable operations in the event of snow and ice tear-off function in the event that a fan is blocked Easy mounting Robust crane lugs to simplify transport by crane Small number of legs and hence fewer bases and fewer attachments Factory-fitted assembly groups (control panels, empty casings, etc.) Inspection and cleaning Easy access for cleaning Optional inspection opening or hinged fan plates Constant high capacity Special fin geometry for effective cleaning 4 5

References Process cooling In this factory, the company Glockenbrot produces baked goods for branches all over Germany. This involves processing 100 tonnes of flour every day. Güntner fluid coolers cool the refrigerating machines required for process cooling. Height above sea level extreme conditions Germany s highest transmitter is operated by the Bavarian broadcasting company BR in the Alps. Güntner fluid coolers are in operation in all weathers at an altitude of 1,800 m. Fish processing corrosion resistance One of Europe s largest and most modern fish processing plants is on the Baltic island of Rügen. Installing condensers and fluid coolers on the coast calls for special corrosion protection measures. Güntner s special corrosion-proof condensers fulfil these requirements. High cooling power special assembly situation London is home to one of Europe s largest shopping centres. A total of 61 Güntner fluid coolers equipped with speed controllers provide for a pleasant atmosphere. Such a large number of fluid coolers calls for special measures for the assembly and installation. The speed controllers ensure that the required noise levels can be achieved day and night. Protection of historic buildings The Altmarkt-Galerie shopping arcade in Dresden operates 20 GFH fluid coolers to ensure a pleasant atmosphere. Utilising the free cooling mode of operation saves energy amounting to 95,000 kwh per year. To protect the historic building the fluid coolers were arranged at an angle and integrated into the building. Stringent noise requirements Refrigeration equipment with a total cooling power of 3.5 MW is installed at the Rinecker Proton Therapy Center. The location of the fluid coolers called for a non-standard assembly and compliance with extra stringent noise requirements. More at: www.guentner.eu/know-how/references 8 9
