Description of compressors
SMC 186-188 Mk2, TSMC 188 Mk2
0178-902-EN 96.12
The SMC 180 and TSMC 180 compressors
have 180 mm diameter pistons, as indicated
by the first digits in the type designation and
with a stroke length of 140 mm. The number
of cylinders in the compressor block is indicated
by the following digit, where, for example,
SMC 188 is an 8-cylinder compressor.
SMC 180 is a one-stage compressor which
compresses the gas in one single stage.

In the TSMC 188 two-stage compressor, the
gas is compressed in two stages at a ratio of
1:3 between the number of high- and lowpressure
cylinders. Thus, a TSMC 188 has 2
high-pressure cylinders and 6 low-pressure
cylinders.
The type can be determined by the nameplate,
located on the end face of the compressor,
facing away from the coupling/belt
drive. The following illustration shows a
SABROE name-plate.

Similarly, the name-plate indicates the compressor’s
serial number, which is also stamped
into the compressor housing near the suction
chambers.
Whenever contacting SABROE about the
compressor, its serial number should be
stated.
The pistons operate in cylinder linings, which
are inserted in the frame with two cylinders
under each top cover. The suction valves, of
