How loud is the generator or is there anything disquieting in its operation?

SG Classic in SG Climate
Regarding the fact that the generator is not used in, for example – bedrooms, where we wish total absence of sounds of any device – the generator is unobtrusive.

If you wish to use it in the room where total silence is required, it would be practical to ask our representative for a demonstration of the device.

SG Intuition
Is appropriate for the use in rooms where silence is desirable. Working sound of the device is inaudible.
