A Concerted Effort

At Güntner, research and development plays a major role in our efforts. At our main office in Fürstenfeldbruck, Germany, alone we have over 50 employees involved in R&D. In addition, there are development teams at our production locations in Indonesia, Mexico and Hungary. This means that, worldwide, Güntner has almost 80 employees pursuing the R&D necessary to make our products the best available. These R&D efforts not only cover product design, thermodynamic calculation and testing but also software development and product-data management.

The Development Process at Güntner

At Güntner, development of new processes is based on a clearly defined product development workflow. Each development is first preceded by a preliminary study during which fundamental questions with respect to market requirements and technical feasibility are examined and resolved.



Thermodynamic Design
All new development work usually starts by preparing a thermodynamic model. In preparing this design study, Güntner uses the most modern industry-wide software tools and even uses its own specially developed software.


Design
As soon as the fundamental thermodynamic characteristics for a new product model series have been established, the first design drawings are prepared. During the design development phase, the feasibility is also tested and possible solutions are compared and contrasted based on value analyses.

 

Prototyping
Despite their clear benefits, even the most modern computer programs cannot replace practical testing. The first product prototypes are built and tested during the design phase. The only devices that are actually manufactured are those that have first proven themselves during this comprehensive practical testing.



Prototype Evaluation
All new product designs are examined in our test facilities to determine their actual technical properties and features. This work is done in our own internal testing department equipped with its own modern measurement chambers and instruments. As a Eurovent-certified company, we guarantee that the specified performance values can actually be achieved and that the desired sound pressure levels are met.

 

Series Production
Only after all the technical testing has yielded the desired results do our design teams begin preparing the final drawings and schematics. Each new product requires its own set of drawings, in particular detailed section drawings. Our data management system makes these drawings available to all of our locations worldwide so that a given product can be made in any one of our production facilities.

Our Testing Department

Güntner GmbH & Co. KG has its own internal research and testing department. There’s a real need for this capability, for without measuring their actual performance, reliable statements about the critical properties of finned heat exchangers, such as their thermal performance, pressure drop or noise levels are essentially impossible. Without such testing, these properties can be known only to a limited or just a very rough extent. Having our own in-house testing facilities means that we can handle both large, longer research projects as well as shorter, experimental testing sessions intended to answer specific technical questions.

Both examinations are done in close cooperation with the technical department concerned. One of the biggest advantages of having our own internal testing department is that it allows us to quickly employ the newly gained knowledge, expand on it and immediately apply it to our development work, bringing about immediate improvements in our products. The technical capabilities of our research and testing department allow us to conduct both broadly defined and application-specific investigations as well as examine the actual feasibility of special customer requirements.

In all cases, we’re able to derive a reliable basis for technically implementing the results. This process capability allows us to continuously improve the performance and features of our products, thus ensuring the greatest customer satisfaction.

 

Performance testing, material-combination testing and special projects
Our primary work involves conducting performance testing of evaporators and condensers as well as heat exchangers for use with various fluids. To be able to examine a broad range of performances, we have measurement chambers available in different sizes & capacities. Our measurement setups and accuracies are in full compliance with the following industrial standards: EN 327, EN 328 and DIN 1048.
We also have a special test facility that allows us to investigate the cooling performance of evaporators in real-world applications and under extreme operating conditions. In addition, we conduct detailed examinations of various material combinations for different unit models.
Beyond this, special research assignments from all sectors involved in heat transfer technology are accepted and treated in our test facility. In short, we're able to find solutions even for very special applications.
