10.1. Short Term Storage (less than 6 months)
All heat exchangers and components must be stored in a cool and dry environment
away from sunlight. They must be protected from water and debris with a waterproof
cover, while also allowing for air circulation. Please refer to document GPHE IOM-
GASKET for the detailed gasket storage procedure.
10.2. Long Term Storage (more than 6 months)
All heat exchangers and components must be stored in a cool and dry environment
away from sunlight. They must be protected from water and debris with a waterproof
cover, while also allowing for air circulation. Please refer to document GPHE IOM-
GASKET for the detailed gasket storage procedure.
All connections must be closed to prevent water or debris from entering the heat
exchanger. Factory installed plugs or covers may be used.
To extend the gasket operation lifetime, it is recommended to relax the gaskets by
loosening the tie bars by approximately 10% of the compressed plate pack dimensions.
Please refer to document GPHE IOM-STORE for the detailed long term storage
procedure. This procedure must be used when a heat exchanger will not be placed in
operation within six months after shipment from the factory or when an installed heat
exchanger will be out of operation for more than six months.
Ozone-producing equipment, salt air and other corrosive atmospheres must be
avoided.
The plate pack must be tightened to the correct pitch before commencing
operation. Use the maximum pitch when new plates and gaskets are installed.
For all other conditions, tighten the plate pack to the previous plate pack
dimension and if leaks occur then reduce the plate pack dimension in small
steps. Never tighten the heat exchanger below the minimum pitch.
A heat exchanger which has been in storage for more than five (5) years should
be inspected by a qualified SPX FLOW representative prior to preparing it for
operation.
