Alternative to oil cooling: direct liquid injection (LI)

Direct liquid injection is an alternative to oil cooling in certain cases, provided that a reliable function is guaranteed. For some compressors, liquid is injected into the existing economiser connection, for others a separate LI connection is available (see dimensional drawings in the Bitzer Software).

For further information see Technical Information ST-610, chapter "ECO operation combined with liquid injection (LI) for additional cooling".
