Areas of application of screw compressor unit
Application
To prevent unintentional application of the com-
pressor, which could injure personnel or damage
the equipment, the following must be observed:
•
The compressor must only be used as a re-
frigeration compressor with the number of
revolutions per minute and within the oper-
ating limits specified in the manuals or in a
written agreement with
Sabroe Refrigeration.
•
The compressor must only be used with the
following refrigerants: R717, R22, R134a,
R404A, R507, R600, R600A, R290 and
LPG. Other HFC refrigerants must only be
used in accordance with
Sabroe Refrigeration's instructions. All oth-
er types of gas must only be used with a
written permission from
Sabroe Refrigeration.
•
The compressors are approved for applica-
tion in potentially explosive atmospheres
provided they have been fitted with explo-
sion-proof equipment. This can be seen
from the Ex name plates fixed on each unit.
See Fig. 1.

Please note that special tools which do not cause
any sparks must be used for ALL maintenance
work on the compressor.

Warning!
Sabroe Refrigeration is not liable for injuries to
personnel or damage to equipment resulting from
using the equipment for other purposes than the
ones stated above.
Application of combustion engines
If combustion engines are installed in rooms con-
taining refrigeration machinery or rooms where
there are pipes and components containing refrig-
erant, make sure that in case of leakage the com-
bustion air for the engine comes from an area in
which there is no refrigerant gas.
Failure to do so involves a risk of lubricating oil
from the combustion engine mixing with refriger-
ant. At worst this may lead to corrosion and dam-
age of the engine.
W
Warning!
The compressor must NOT be used:
•
For evacuating the refrigeration plant of
air and moisture.
•
For putting the refrigeration plant under
air pressure in view of a pressure test-
ing.
•
As an air compressor.
