Operating Instructions
Compressors
Pump Ranges
These operating instructions concerns the following dry
running rotary vane compressor: DTE 8 (50), (51), (52)
Model DTE 8 has a capacity of 8 m
3
/hr. The overpressure
is 0.4 bar on S1 and 0.8 bar on S3 60 %.
Description
Both the motor and compressor have a common shaft. The
versions (50), (51), (52) of the DTE differ in different plug
connections (J).
The compressor is driven by a DC motor.
Suitability
The units DTE are suitable for the use in the
industrial field i.e. the protection equipments
corresponds to EN DIN 294 table 4, for people aged 14
and above.
The DTE compressors produce compressed air up to the
maximum limits, which are shown on the data plate (N).
They may be operated continuously.
The ambient and suction temperatures must be
between -25 and +50° C. For temperatures outside this range please contact your supplier.
These dry running compressors are suitable for use with air of a relative humidity of 30 to 100 %.
Dangerous mixtures (i.e. inflammable or explosive gases or vapours), water vapour, aggressive gases or
traces of oil and grease must not be handled.
The standard versions may not be used in hazardous areas.
All applications where an unplanned shut down of the compressor could possibly cause harm to persons
or installations, then the corresponding safety backup system must be installed.
Handling and Setting up
Compressors that have reached operating temperature may have on the DTE 8 a surface temperature at
position (Q) of more than 70° C. WARNING! Do Not Touch.
There must be a minimum space of 20 cm in front of the housing cover (d) for servicing.
The DTE compressors can only be operated reliably if they are installed horizontally. Other built-in positions
on request.
For installations that are higher than 1000 m above sea level there will be a loss in capacity. For further
advice please contact your supplier.
Installed on a solid base these compressors may be installed without fixing down. If the compressors are installed on
a base plate we would recommend fitting anti-vibration mounts. This range of compressors are almost vibration free in
operation.
Installation
For operating and installation follow any relevant national standards that are in operation.
1. Pressure connection at (B).
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the
compressor.
2. The electrical data can be found on the motor data plate (P). The motors correspond to DIN/VDE 0530 and have IP 65
protection and insulation class F. Check the electrical data of the motor for compatibility with your available supply
(voltage, polarity, permissible current etc.).
3. Connect the motor via plug-connection (J) anschließen (plug reference see data sheet 961271 or 961272).
The electrical installation may only be made by a qualified electrician under the observance of EN 60204.
The main switch must be provided by the operator.
