If a compressor needs to be installed in new appliances normally there is enough time available to choose
the right compressor type from data sheets and perform sufficient testing. On the contrary, when a faulty
compressor needs to be replaced it can be impossible to get the same compressor type as the original in
many cases. That is why it is necessary to compare relevant compressor catalogue data.
A compressor can provide a long durability if service work is done in the right way and attention is paid
to keeping parts clean and dry. The service technician must observe the following when choosing a com-
pressor: type of refrigerant, voltage and frequency, application range, compressor displacement/capacity,
starting conditions, and cooling conditions. If possible use the same refrigerant type as in the faulty system.
The Secop hermetic refrigeration compressor programme consists of the types:
P / T / X / D / N / F / S / G-Series and DELTA / KAPPA
P T DELTA X D KAPPA N F S G
All compressors for 220-240 V have a yellow label with the type designation. Compressors for 115 V have a
green label with the type designation.
Direct current compressors and variable speed compressors have a gray label.
The label for “R404A R507” or “R404A R407C R507” has a lilac stripe. The label for “R134a” has a blue
stripe. The labels for “R290” and “R600a” both have a red stripe.
The labels for the DELTA, KAPPA, and XV compressors do not follow all rules.
The country of origin indicated on the com-
pressor paper label and on the compressor
varies depending on the place of manufac-
ture.
If the type label has been destroyed, the com-
pressor type and the code number can be found
on the engraving on the side of the compressor.
For information please refer to Product Bulletin
"Date Code Format & Country of Origin".
LST/HST mentioned both means that the start-
ing characteristics are depending on the electri-
cal equipment.
Barcode format
A Secop compressor type label contains two barcode lines. The first line is the full code number of the com-
pressor and the second line is the compressor serial number. These barcodes contain 8 characters each
and are printed in code 128.
Serial number
The compressor serial number will also be written in normal letters below the barcodes
The serial number contains 8 digits, written in characters 0–9 and A–Z, excluding I and O.
