How we handle Bitzer requests
Many vessels still run the older semi-hermetic 4CS/4TCS/6FE-series compressors, which Bitzer has since replaced with the ECOLINE 4ES/4PES/4TES range using the same connection sizes — so parts requests often need to specify whether the unit is the legacy model or the ECOLINE replacement. A compressor model, serial number, refrigerant and nameplate photo make the review much faster.
Customers can send part numbers, maker references, equipment model data, serial numbers, nameplates, photos, drawings, old offers or previous supply documents. We review the information before quoting so the request is handled as a technical procurement task rather than a generic product search.

Parts and equipment we can review
Bitzer RFQ scope
Use this page when your purchasing or engineering team needs review by part number, model, serial number, drawing, photo or old commercial reference.
4NES / 4PES / 4TES ECOLINE compressor parts
4NES / 4PES / 4TES ECOLINE compressor parts are checked against compressor model, stage and serial number, since running gear varies by build revision.
6FE / 6GE / 6HE larger compressor series
For 6FE / 6GE / 6HE larger compressor series, the compressor model and capacity data help confirm fit before quoting.
compressor valve and gasket service
On compressor valve and gasket service, connection size, pressure rating and actuation type (manual, solenoid, pneumatic) are the details that matter most.
filter and oil control references
For filter and oil control references, a photo of the old element or its printed part number avoids ordering the wrong housing fit.
pressure and temperature controls
Range, output signal and process connection are the key specs we check pressure and temperature controls against.

How to send a useful Bitzer RFQ
Attach the clearest technical information available. A single photo of a nameplate, an old offer line or a marked drawing can prevent delays when there are similar models, revisions or connection types.
If the item is obsolete or hard to identify, include dimensions, application notes and any alternative references already checked by your engineering team. We can review the request and reply by email with the next steps.
