Serial number and date
code information
Danfoss does not serialize the compressors but
we do put a date stamp on them. Stamped into
the shell above or just to the right of the paper
label are two lines of data. The first line states
the model designation and the code number,
e.g. L-4CL-2071:
L = last letter (or last two letters) of the
compressor type,
4CL = nominal displacement,
2071 = 4 last digits in the code no.
The second line contains the manufacturing
place, the date of manufacture and an internal
code,
e.g., F-202E2207:
F = Manufacturing place (F = Germany, AL =
Slovenia, AM = Mexico),
20 = week 20,
2 = 2002,
E = Friday (A = Monday, etc.),
220 = nominal voltage,
7 = internal Danfoss Code.
Beginning in 2002 Danfoss started to introduce
a new coding consisting of two lines,
e.g., H47117:
043C12A.
First line:
H4711 = 5 last digits in the code no.,
7 = internal Danfoss Code.
Second line:
04 = week 04,
3 = 2003,
C = Wednesday (A = Monday, etc.),
12 = Internal Danfoss Code,
A = Manufacturing place (A-G = Germany, K-N =
Slovenia, R-S = Mexico).
