What type and what amount of oil are Secop compressors charged with?
The amount of oil we charge our compressors with can be found in the data sheet of the individual compressor. The data sheets can be found and downloaded in the Data Sheet Selector on our website.
More information can be found in our catalogues which contain an introductory section with some information on use, oil type, starting equipment and application limits for the Secop compressors.
The compressor oils Secop uses are:
For R134a compressors:
- PL and TL: 15 cSt POE oil
- NL and FR: 19 cSt POE oil
- SC: 22 cSt POE oil
For R600a compressors:
- TL: 7 cSt or 10 cSt mineral oil
- NL: 15 cSt mineral oil
For R404A compressors:
- All types use 32 cSt POE oil
All refrigeration oil types Secop uses do not contain any additives, only antioxidant is allowed.
Are Material Safety Data Sheets (MSDS) available for the compressor oils Secop uses?
Secop has MSDS sheets for the original oil that will be handed out to customers on request. Please contact your local Secop Company.
What parameters determine the lifetime of a compressor and what can typically be expected?
Important factors determining the lifetime of hermetic compressors are:
- system dimensioning and system lifetime
- system temperature, esp. valve and winding temperature
- system pressure
- purity of system components
- quality of refrigerant and oil
- lifetime of other system components
- quality of main power supply (cut-outs, voltage drops etc.)
- application duty cycle
In a typical application where the compressor is used within the specified limits given in the actual product literature a lifetime of 10-15 years can be expected as rule of thumb.
The lifetime of a compressors used in a household application may be longer than the lifetime in a light commercial application.
Do you have a mathematical equation and coefficients for the calculation of the compressor data?
Yes, we publish our compressor performance data according to the ARI
standard 540-91 and EN 12900.
We will gladly provide data for specific compressors if requested. Please contact us via our contact form. (link)
What determines the noise level of a cooling system?
The most relevant factors are:
- combination of components in the cooling system (layout and installation)
- pulsations and turbulences in the refrigerant gas related to the specific system
- actual level of system insulation
- fx of machine compartment
- actual system vibration prevention
- suction and/or pressure mufflers
What is the noise level of a Secop compressor?
The Secop compressors are extremely low noised compared to the average competition products. Please contact us under firstname.lastname@example.org, email@example.com or firstname.lastname@example.org for specific information.
How does horsepower compare to capacity in W or Btu/h?
Horsepower or hp is a historic designation for the engine performance. There is no official standard relation to refrigerating
capacity. All manufacturers have developed their own formula. Therefore data stated in hp by different manufacturers can not be compared.
Furthermore, a capacity given in hp is dependent on the application range of the compressor, i.e. 1 hp of an air conditioning compressor is
different from 1 hp of a LBP compressor.
If the capacity in W or BTU/h at given conditions is known this should be preferred for comparison.
Does Secop use internal or external motor protection switches?
The position of the motor protection switch on Secop compressors can be determined from the second letter of the compressor's nomination for the P/T/D/N and F-series. "T", "F", or "LV" indicate an external protector. "L" and "R" indicate an internal protector.
For the SC compressors please check the data sheet of the individual compressor. For most types the protector is internal, only some 115V/60Hz types are equipped with an external protector. In these cases the protector is shown as a separate part in the figure (f) and listed in the list of accessories in the data sheet, too.
For more information on Secop compressors' designation see Key to Compressor Type Designation.
Why is the compressor housing hot?
Secop compressors are not cooled by suction gas but with the oil
circulating inside the compressor housing. The housing then transports the heat to the surroundings.
What is the meaning of the serial number on the compressor?
Serial numbers were introduced in July 2004. The serial number is individual to each single compressor. There is no relation between serial number and production date, shipment day or the like. The serial number has been introduced to help our customers, who are using the individual compressor serial number in the documentation for their appliances.
The production date can still be found in the stamped code on the compressor housing (check Data Code).
How can I read the date stamp on the compressor?
What information does the date stamp on the compressor housing provide?
Secop puts a date stamp on each compressor. Two lines of data are stamped into the housing above or just to the right of the paper label. 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.
In 2002 Secop started to introduce a new coding consisting of two lines, e.g.:
H4485 = Compressor type information (102H4485 = H4485)
C = internal Secop Code.
05 = Production week
1 = Production year
D = Production day (A = Monday, B = Tuesday, etc.)
11 = Production hour 00 to 23 or shift code -1, -2, -3
R = Secop internal production location code
A-G, U = Germany
A until week 50/2005
D until week 35/2006
U until week 08/2010
K-N = Slovenia
L until week 34/2011
A, D, L, R, U Slovakia
A from week 01/2006
D from week 38/2006
L from week 44/2011
R from week 01/2005
U from week 12/2010
R up to week 27/2004
W to Z China
For more information view the product bulletin "Date Code Format & Country of Origin" on our website.
The paper label is unreadable, how do I know what type of compressor I have?
Two lines of data are stamped into the housing above or just to the right of the paper label. 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.
With this information please contact your local Secop representative which will further assist you.
How can the type code on a Secop compressor be interpreted?
The type code consists of separate single letters.
The first letter stands for the compressor series ("BD", "P", "D", "T", "N", "F", "S" or "G").
The second letter indicates the protector location, where "L", "R" and "C" mean an internal, "T", "F" or "LV" an external protector.
The third letter gives the optimization level:
E = energy optimized,
S = semi-direct intake,
Y = highly energy-optimized,
X = very highly energy-optimized
The number denotes the displacement in ccm. For P and BD compressor types it gives the cooling capacity in W at rating point.
The letter that follows gives the application range and the refrigerant.
The next letter denotes the starting characteristics:
" " = universal
"K" = LST characteristics (capillary)
"X" = HST characteristics (expansion valve)
The last digit means the generation in development:
" " = 1st generation
"2" = 2nd generation, etc.
