Problem-free and economic compressed air system
The Altia Plant in Rajamäki, Finland, bottles and bags about 20 million
litres of wine annually. The wine is transported from around the world
in freight containers, stabilised in terms of microbes and proteins.
Wine is a sensitive product which needs to be protected over the entire
transport, storage and bottling process. The growth of harmful microbes
is efficiently hindered using nitrogen as a protective gas.
Nitrogen is fed into the containers to displace the air, and the oxygen
in the wine is also “caught” by small nitrogen bubbles that rise to the
surface and exit the liquid.
The nitrogen comes from pressurised (7 bar) ambient air through a
nitrogen generator, and is always available, without such complications
as the ordering or storage of nitrogen gas.
The nitrogen generators at the Rajamäki plant take the compressed air
from screw compressors through adsorption dryers and filters.
The entire compressed air system is regulated and controlled by Sarlin
Balance, guaranteeing problem-free and economic air compression. The
cooperation between the supplier and the customer proved valuable at the
