Choosing your gas cooler is simple and safe with Windy
CO₂ cooling plants are a highly efficient technology, but also one that requires a high degree of design sensitivity.Every component must be carefully calibrated, and no choice can be left to chance: the overall performance, durability and energy consumption of the system depend on it.
As a result, even the choice of the gas cooler – a key component in the systems – must be taken with the utmost accuracy. This is the rationale behind Windy, the online selector developed by Stefani to guide designers or customers in choosing the right model and accessories quickly and easily.
To ensure that the software accurately reflects operational reality, Stefani conducted a laboratory test, comparing the results provided by Windy with laboratory tests on a real machine. A key step towards offering a reliable, validated tool.
The test
To make the comparison, Stefani designed a special gas cooler, which was tested in a certified laboratory using a system that simulates the operating conditions of R744 (CO₂) refrigerant.
The test was designed to represent many different types of climate situations: a wintery climate, one typical of northern Europe and on of southern Europe.Under each operating condition, we measured:
The result is clear-cut: all the values fall within a very narrow tolerance of ±3%, confirming the accuracy and reliability of the software even under very different conditions.A concrete verification that certifies Windy as a highly professional tool, essential for the selection of machines.
Windy: simple, complete, precise
Windy is an online selection software, designed to be intuitive and user-friendly, but also complete and highly configurable. It is designed to be an everyday tool for designers, technical firms and installers.
In addition to selecting the most suitable model based on project data, Windy allows you to directly configure all available accessories, such as EC fans, silencers, adiabatic versions, etc. All in a single session, with a clear and intuitive interface.
This provides a complete overview of the configuration, expected performance and actual dimensions of the selected product, without the need for further steps or additional consultations.
In conclusion
Design precision and performance in the field have always been the strengths of Stefani’s products.With the Windy software, these qualities are also carried over to the preliminary selection phase, making the process simpler, more reliable and more professional.
Through its experience in the field and investment in the new configurator, Stefani can offer its customers an effective tool for selecting the right machine, with the certainty of achieving the expected performance.
Windy is the natural digital evolution of a brand that has always combined sturdy construction with a focus on promised performance.
With Stefani gas coolers, Windy comes full circle: it applies the design parameters to select the right model and accessories (ventilation, noise reducers, adiabatic option) to optimise power, size and noise levels.
The result?A quick, safe transition from selection to the field: machines sized consistently with data and performance that make the difference.
