To help you get a better understanding of our unique Mikrofill EFD filling device we have developed an online simulator.

The simulator accurately emulates real world installations and can be easily configured to match your system, it can also be used to demonstrate real world problems caused by leaks, over temperature, incorrect vessel sizing and charge and so on.

We have also included a useful tool for sizing and specifying your expansion vessels as well as brief explanations of the water regulations relating to sealed systems and backflow prevention.


Why not download the simulator (also do this if you are having difficulty viewing from within the webpage). Choose your operating system:
