BRING YOUR ELECTRONICS UP TO OPERATING TEMPERATURE
Whether as a concept study or as a detailed device simulation: in all branches of industry in which modern electronics generate high power, the thermal loads should remain low. We help you simulate heat generation and find optimal solutions.
Your specialists for electronics cooling
We make sure your electronics don’t overheat and that they work reliably. Whether you’re looking for component cooling inside a device or the air conditioning of an entire server room: we offer the right software tools to help you reliably simulate heat generation.
And best of all, besides selling the corresponding CFD applications, we also know how to use them, which means that we can share our in-depth knowledge with you in comprehensive workshops and training sessions, or carry out simulations or modelling for you, when purchasing a full license would not be cost-effective for your requirements. We thus offer individual solutions for any situation – from a small SME to a major corporation and provide active support with equipment development for your R&D department or for your IT team in the data center.

Our software
Simple operation, complex calculation: Celsius EC (known as 6SigmaET) is a CFD tool tailored for electronics development.
Applications
Electronics components are becoming increasingly compact. CelsiusEC provides reliable information on what to look out for in your equipment cooling system.
Techn. Article
Take a look at our PR portals. For many years, we have been publishing technical articles on CFD simulation for electronics development.
Training
We don’t leave you alone with complicated user manuals. Instead we offer you individual product training and seminars.
Service
Not only do we sell innovative software – we also put it into practice. On request, we’ll carry out modeling and simulations for your organization.
About us
We’ve been serving our customers since 2009. Here we show you the faces behind ALPHA-Numerics and introduce ourselves.
CAD-based CFD simulation
As a rule, all thermal paths such as heat transfer, convection and thermal radiation are calculated on the basis of a CAD assembly imported to CelsiusEC via STEP data with no prior simplification. Hardware details can be added at the touch of a button via IDF, Gerber, ODB++ and other interfaces.
Making heat paths visible
As a result of this type of simulation, you receive all the surface temperatures on the mechanical systems or electronics hardware. Component, PCB and other temperatures can be directly exported to Excel.
CAD-based CFD simulation
As a rule, all thermal paths such as heat transfer, convection and thermal radiation are calculated based on a CAD assembly imported to 6SigmaET via STEP or native data with “no” prior simplification. Hardware details can be added at the touch of a button via IDF, Gerber, ODB++ and other formats.

Trial license
Try before you buy
We don’t want you to make your decision on our CFD tools solely on the basis of a product demo. We consider it vital that you carry out a proper evaluation by using our free, one-month trial license with the parallel support of our introductory documentation material, practice models and our technical support. The software and the functions relevant to your applications should fit your requirements perfectly. But don’t forget that a reliable, competent and fast reacting software partner with a sophisticated hotline and technical email support is an important factor to ensure that this software is safe to use at any time, even when employed on an irregular basis. At ALPHA-Numerics GmbH we also offer simulations as a contract option, delivering competent answers to your technical queries and also providing you with targeted training.
Our mission: satisfied customers
Each project is different and offers new challenges. This applies equally to the cooling of electronic equipment as it does to the air-conditioning of entire data centers or server rooms. All projects have one thing in common: we’re only satisfied when our customers are satisfied.
