ECO connections
Most screw compressors are equipped with an additional suction gas connection for operation with economiser (ECO) as standard. Various adapters, e.g. with shut-off valves, are available as options.
For the first order, the compressors are supplied with the standard (sealing screw / blind flange) specified here. If one of the options is required, 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.
Nominal diameters (DN) are not actual dimensions!
The nominal diameters DN10 .. DN200 only indicate ranges! The number is not a quantifiable unit, it is only indirectly related to the diameters of the connections and should not be used in calculations.

Valves with the same designation are not necessarily interchangeable!
The above table sometimes contains links to the same valves, but they are supplied in different assemblies. Valves with the same designation are therefore not necessarily interchangeable. When ordering, it is thus necessary to specify for which compressor the valve is to be used.
For further information on the position of the connections on the compressor, pipe layout and ECO operation, see Technical Information ST-610. In addition, the respective operating instructions for the compressor must be observed.
