Web-based simulation for engineers, sales and marketing. Understand complex products easily with sim.TLK Apps!


Simulate your systems easily and present results to your clients right on the spot.

Visualize your product's performance to help your clients understand its benefits.

Impress your customers with modern simulation apps and a perfectly matching product selection.
Engineers have been using computer simulations for a long time to improve technical systems. However, most simulations require expensive software and special training. sim.TLK Apps make a difference: our easy-to-use engineering apps highlight the performance and benefits of your products, thus opening up completely new possibilities for your technical sales team.


At TLK Energy, we are an interdisciplinary team of engineers, software developers, and designers. Our long-term experience, constant exchange with our customers and openness to new approaches and methods allow us to find outstanding solutions. We accompany your project from requirements analysis to model development and interface design.

We recommend whether an existing model should be used, adapted, or built from scratch.
Using sim.TLK, we turn the model into a web application and customize the interface, results, and branding.
