Commercial refrigeration plant manufacturer Eletrofrio has set up an in-house laboratory for CO2 commercial refrigeration to reliably fill this gap in the market, particularly with individually optimised transcritical CO2 systems. The heat is dissipated on the high pressure side by a Güntner gas cooler.
The continual feeding of biogas into the natural gas network significantly improves the efficiency of biogas facilities. The piston compressor manufacturer NEUMAN & ESSER has developed a mobile biogas system for this purpose and is relying on a Güntner Vario FLAT S-GFH dry cooler for cooling the compressors.
In the village of Trechwitz, a rural area not far from the city of Potsdam in Germany, one of the mostmodern biogas plants in Europe is in operation because of the vast energy potential from manure.
The tower of the Turkmenistan Broadcasting Center with its octagonal star is 211 meters high and can be seen from afar. The construction in the Turkmenian capital of Ashgabat, demanding with regard to architecture and engineering, was a challenge for both construction engineers and craft enterprises. After all, the Turkmenian head of state desired to have a first broadcasting center to go on air after a four-year construction period on the 20th anniversary of the declaration of independence.
The Siberian climate represents a particular challenge for refrigeration engineers when it comes to producing power from gas. The Slovakian Elteco company installed Güntner fluid coolers as well as thermowave plate heat exchangers in Siberia to dissipate heat produced by five 2 MW gas generators.
Two Güntner aircooled cooling towers, model
S-GFH, operate at a lofty height, at the highest situated transmitter station of Germany, operated by the Bayerischer Rundfunk on the Wendelstein.
61 customized drycoolers with sine controllers ensure a well-tempered atmosphere in London. Due to the sine controllers, the units are even especially low-noise.
The historical restaurant "Zum Franziskaner" uses state-of-the-art Güntner units to cool their famous beer to perfection.
Fish processing makes the highest demands on hygiene, corrosion resistance, ease of maintenance and longevity. Choosing the right equipment, it is even an economical solution.
Russia's growing importance in global economy attracts more and more international companies who increase their presence in the Russian capital.
A total refrigerating capacity of approximately 3.5 MW serves to cool the Rinecker Proton Therapy Center.
The demands regarding the quality of dairy products like fresh milk, yogurt and butter are high: from the processing to the storage of the sensitive products, swift and unobstructed cooling processes must reliably be ensured.
An unusual project started by a utilities company,the Stadtwerke Rosenheim in the south of Germany placed high demands on performance and sound insulation.
In Dresden's Altmarkt Galerie Mall, 20 drycoolers of the type GFH ensure a pleasant temperature and save energy at the same time.

Which benefits do you as a customer have?
Güntner has the high standard of producing high-quality, application-oriented heat exchangers and remaining both fair and transparent. That is why we participate in a corresponding program from Eurovent. The goal of the Eurovent Certification Company is to promote fair competition and to guarantee the customers that the units on the market are inspected under the same conditions and that they are therefore easier to compare. The manufacturers’ specifications are examined by independent laboratories for this purpose. To do this, units from the respective manufacturer are selected randomly.
The HE Program (Heat Exchangers for Refrigeration) for heat exchangers of the refrigeration and air conditioning industry has existed since 2001. Güntner has participated successfully without interruptions since the implementation of the program; all of the series included in the program are certified without exception – and have been for 15 years!
The Eurovent certification of the HE Program includes DX evaporators and condensers that are designed for R404A, R134a, R507A, R407A, R407C or R407F.
The Eurovent certification program is designated for air coolers with fluids, NH3 evaporators and condensers as well as CO2 evaporators and condensers, 60 Hz units and centrifugal fan units. A certification for CO2 gas coolers and CO2 DX evaporators as an individual group of units is scheduled from 2017.
Operating certified units provides you with significant advantages that are worth real money:
- The classification of units into energy efficiency classes is an important characteristic of the certification providing you with information on the energy consumption you can expect from the selected unit. This means the operating costs can clearly be identified.
- The independently measured, inspected specifications give you certainty when it comes to designing the units. You can design precisely to the operating point; safety margins are not required.
- Units are easier to compare with each other thanks to certified specifications. This results in fair competition under realistic conditions.
- The certify-all principle guarantees that manufacturers cannot distinguish themselves through individual “top-seller” units: Complete series are certified, hence there are no loopholes for individual units.
- The confirmed and therefore reliable technical data increase the investment security and guarantees planning security and operational reliability with regard to performance and energy efficiency of the entire system. The operating costs can clearly be calculated right from the beginning.
- Certified units save real money: “We recommend that every operator calculates the energy consumption for a current or future construction project because of a hypothetically insufficient capacity. A few years ago, non-certified units showed insufficient capacities of up to 35 % in a serial examination. Thus, you can realistically expect a reduced output of 15 – 20 % for calculation. In comparison, there is a clearly better payback period for the certified unit, usually clearly under 2 years”, according to Peter Roth, Eurovent officer at Güntner.
- The Eurovent certification of the selected units is an indispensable prerequisite for receiving subsidies from defined funding programmes. The certification applies to all standard units. Through its modular variability, the new Güntner product structure includes an even wider range of certified units that come into question for funding measures.
