Guarantees

All elements of the installation including the diffusers will be guaranteed
for a period of one year. Extended warranty periods can be negotiated for
a small additional cost.

Written guarantees will be provided to ensure that agreed levels of efficiency
and performance are delivered. These are site specific but aeration efficiency
guarantees of 4kg O²/kWh are common.

Linked to our planned maintenance program we can ensure the smooth running and
efficiency of our installations for the life time of the plant.
