Customers can select the configuration that best suits their individu-al requirements from a variety of different ma-terial combinations, variants and accessories.

Vario

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 ideasWhether you are looking for a condenser, gas cooler or fluid cooler, you will always find the per-fect solution to meet your specific needs with our Vario units – plus our extensive range of acces-sories.

Optimised key componentThe extensive, modular heat exchanger concept with numerous tube geometries and optimised tube circuiting allows for precise designs – plus special designs offered as standard solutions.

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

Unbelievable energy efficiencyHigh-quality fans paired with Güntner's sophis-ticated control concepts produce unbelievably energy-efficient units. Plus calculation directly at the operating point and certification.

* Güntner profile is only available in Europe2 3

Inspection and cleaning• Easy access for cleaning• Optional inspection opening or hinged fan plates• Constant high capacity• Special fin geometry for effective cleaning

Versatile• Condensers for synthetic refrigerants,

hydrocarbons and ammonia• Gas coolers for transcritical CO2 systems• Fluid coolers for water/glycol mixtures• Oil coolers for process and machine cooling

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.)

Unbelievable energy efficiency • AC/EC technology• ErP-ready• Calculation of sound power directly

at the operating point• Control concepts adapted specially for the unit

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 when transported by crane or fork-lift truck

• Snow/wind loads taken into account statically

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

Certified capacity specificationsAs 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.

Condenser / Heatpump (summer/winter)• Optonal heatpump integrated as one with

condenser• No additional heating required• Save space • Save energy (no additional heating system

required)

Protection of historic buildingsThe 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 inte-grated into the building.

ReferencesProcess coolingIn 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 resistanceOne of Europe’s largest and most modern fish pro-cessing plants is on the Baltic island of Rügen. In-stalling condensers and fluid coolers on the coast calls for special corrosion protection measures. Günt-ner’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 atmos-phere. 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.

Stringent noise requirementsRefrigeration 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.
