Amortisation
It is well known that air in water impairs heat
transfer and therefore reduces the efficiency of
the boiler and radiator. Radiators start to move
from conventional to radiated heat. This
increases the comfort felt by people and the

Perfect solution for all systems
Heating and cooling systems in a network are at particular risk. AIR-SEP® provides the
solution.
Ceiling cooling and heating system
Solar system
For solar systems which contain a high level of anti-freeze foam-type air inclusions are created
in the pipeline which cannot be eliminated manually and result in a serious reduction in efficiency
(see refrigeration catalogue). AIR-SEP® can burst these bubbles by means of vacuum degassing,
allowing the clear concentrate to return to the system.
