The MSK set, from the company Kratki, with a damper Ø 125, is a modern fireplace controller with a screen that can be used with all inserts with air and water jackets.

Its function is to let cold air (for combustion) from the outside of the building directly into the combustion chamber, in such a way that it is as efficient as possible.

Thanks to its use, up to 30% of wood can be saved.
