LI connections
Some screw compressors are equipped with a connection for liquid injection (LI). Various adaptors resp. kits are available as options for this connection. If an LI connection is desired, this must be specified when ordering - preferably with the designation in the following table. Details of the components can be found in the subordinate chapters (see below, also linked from the table).
HS.53 .. 85 and OS.53 .. 85 compressors have a combined ECO / LI connection.
A compressor can therefore only be used with ECO or with LI, not with both at the same time.

Connections with the same designation are not necessarily interchangeable
The above table sometimes contains links to the same connections, but they are supplied in different assemblies. Connections with the same designation are therefore not necessarily interchangeable. When ordering, it is thus necessary to specify for which compressor the connecion is to be used.
For further information on the position of the connections on the compressor, pipe layout and operation see Technical Information ST-610, chapter "ECO operation combined with liquid injection (LI) for additional cooling". In addition, the respective operating instructions for the compressor must be observed.
