SEMI-HERMETIC GOELDNER-COMPRESSOR CONDENSING UNITS, AIR- AND WATER-COOLED
CONDENSOR
Our 2- and 4-cylinder semi-hermetic and open type compressor are the result of over 30 years extensive manufacturing
experience in the field of compressors for refrigeration. A truly amazing feature is the silent operation o f our
compressors, which is achieved by a precision machining and a special way of balancing. In the semi -hermetic
compressor used for high and medium temperatures, the cold refrigerant vapours are conduct ed about the motor wiring
to cool the same. In both semi-hermetic compressors for low temperatures and open type models, the suction gases are
conducted directly into the cylinders. The low temperature version of the semi -hermetic compressor is particularly
interesting. On this version, the motor is ventilated from the outside by means of a special fan exactly in the same way as
on a standard fincooled electric motor. By this method, both an efficient cooling of the motor and a higher specific
refrigerating capacity are obtained. The windings of our semi -hermetic motors incorporate thermistors, so that the motor
is protected. If a slow heating of the winding by overload takes place, the compressor is cut off by the electronic thermal
relays, which is delivered with the compressor. Our standard voltages are 220÷240V /Y, 380÷420V /Y, 50 60Hz, 3phase
current. Optional voltages are available at an additional cost. If the VSB-Soft-Starter is taken, the motor could be
started direct and there has to be no more /Y-start in a wide range. With this the installation is made easier and the
costs will be reduced.
We recommend the use of an automatic electric heater for the housing which maintains the oil and housing temperature
at +77°F to +96 °F (+25°C to +35C) during standstill, thus preventing oil hammers. This thermostatically controlled heater
which we supply at additional costs, needs only be inserted into a tapped blind hole in the bottom plate, it has no contact
with the refrigerant. The 2-cylinder compressors are equipped with an oil splasher and the 4-cylinder models (form type
H/O 34 on) with an oil pump.
