Heat exchangers must be stored indoors and covered for greater protection against
dust, in a location providing temperatures from +1°C to +40°C and relative humidity up
to 90%.
Ensure that no liquids, dust, etc. come into contact with the equipment during storage.
The equipment must be stored in an area free from construction activities and vehicle
transit that could cause accidental damage.
The equipment must not come into contact with the ground.
Adequate free space must be available around equipment to guarantee periodic in-
spections and free movement.
The maximum storage period is 12 months.
Long term storage period (5 years) is possible, if the equipment is ordered with nitrogen
filling.
Upon the expiry of assigned parameters (assigned storage period, assigned service
life) operation of the equipment is stopped, equipment is inspected, repaired (if nec-
essary) and new assigned parameters are established (assigned service life and/or
assigned storage period). If the repair is not possible (or not reasonable) the equipment
is disposed of.
