KEBA Kemro PFD35 floppy disk interface for ENGEL machinery

Old PFD35




The original KEBA Kemro PFD35 is a serial floppy disk drive unit used to interface with certain older models of ENGEL injection moulding machinery (particularly the EC88 and certain CC90 models).

pfd35_backCertain machines that do not have a built-in disk or cassette drive require a unit to be connected externally via the V24 interface for EBIAS, machine and mould data to be saved or loaded.

Unfortunately the original Kemro PFD35 unit is no longer in production and considered obsolete. For anyone who actively uses the older ENGEL machines and either does not currently own a PFD35, has a PFD35 that is broken, wants to move from 3.5″ floppy disks to USB memory or just needs a spare interface – may be interested to know that there is an alternative.


We have a few older ENGEL injection moulding machines without built-in disk drives and were unable to find anyone willing to sell us an original PFD35. When the lithium batteries on the motherboards failed requiring the EBIAS to be reloaded. We found ourselves in a difficult situation.

So we decided to look at producing an alternative interface unit that would be a 100% compatible replacement to the PFD35. After some R&D a small number of these units were produced and this website created for anyone who may be interested.

The alternative interface is available in 3.5″ FDD and USB. The FDD version has a standard 3.5″ floppy disk drive and works exactly the same as the original pfd35 while the USB version has a USB interface for standard USB memory devices such as memory sticks allowing machine and parts data to be easily transferred and kept backed up without the need for obsolete floppy disks.

The unit is based off the original Kemro design and utilizes many of the same or similar components found in an original. In particular the Oki 8085 processor, Western Digital floppy controller as well as the Oki Communications Interface IC’s are identical. In this way the alternative unit can achieve complete compatibility.

Please check either your Engel manual (technical or operators) if you are uncertain as to whether your machine is PFD 35 capable. It will be explicitly mentioned. This is not a compatible replacement for the DC-88 cassette drive, rather consider the emulation software available.

Each unit is sold new and has been tested on an ENGEL EC-88 machine (watch the below video for an operational demonstration). Even if you should already own an original Kemro unit or be considering purchasing a used original – it may be worth noting that this alternative is built entirely of new, non-fatigued components, thereby ensuring a much longer service lifespan.
