Product description
Correct use
The compressor is designed for the recovery and compression of SF
6
-gas and SF
6
-gas
mixtures.
Do not use the device to exhaust or compress liquids or other gases.
Use of the compressor for any other purpose may not be safe.
The manufacturer will not accept any liability in case of injury or damage caused by
use of the compressor for applications for which it was not intended.
The TM5.0B compressor is a dry-running two-stage, low maintenance piston compressor and works
entirely without oil.
The compressor housing is enclosed and thus absolutely gastight.
The position of the 2 cylinders guarantees a smooth running even at high back pressure.
The gas is stored in gaseous or liquid form depending on the pressure.
For cooling the compressor and the compressed SF
6
-gas with ambient air a ventilator and an
intermediate cooler and after cooler are integrated.
The operating overpressure is to be limited to max. pe 4 bar on the suction side by a pressure reducer.
Furthermore, the output pressure has to be monitored by a contact gauge (or pressure switch) which
turns off the compressor in case the max. admissible operating pressure (pe 50 bar) is exceeded.
The compressor is protected against overcurrent by a motor protection circuit breaker.
Lead probes are installed in the motor winding and in each cylinder cap.
When exceeding the admissible temperature the compressor is switched off by
the thermistor.
In case the compressor is integrated in a device or system which is - in accordance with the legal
regulations - liable to registration in the country of operation, the operator is responsible for
commissioning and further tests.
It is not allowed to expose the compressor to humid or corrosive substances permanently.
However in case the compressor has been charged with moisture for a short time it must be
rinsed with pure and dry gas for min. 30 minutes.
For this purpose nitrogen can also be used if the rinsing gas is released into the atmosphere.
Finally evacuate the compressor.
Furthermore the compressor must not be operated with substances containing oil and oil mist as this
would damage the piston and guide rings.
Do not switch on the compressor if the input or output pressure or pressure in the housing is < 100 mbar
(absolute pressure). After evacuation flood the compressor with SF
6
before it is put into operation.
Otherwise this could result in flashovers or leakage current on the grommet.
