Operating Instructions
Compressors
Pump Ranges
These operating instructions concern the following dry run-
ning rotary vane compressors: Models DTE 3 ➝ DTE 10.
The pumping curves showing capacity against pressure can
be found in data sheet D 387.
Description
All models are complete with a silencer on the inlet and a pipe
connection on the outlet. All the air handled is filtered by a
built-in micro-fine filter. The motor fan cools the motor and
compressor housing. Both the motor and compressor have
a common shaft. A pressure limitation valve is fitted as
standard.
Optional extras: As required, pressure regulating valve (ZRD),
non return valve (ZRK) and motor starter (ZMS).
Suitability
The units DTE are suitable for the use in the indus-
trial field i.e. the protection equipments corre-
sponds 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 5 and 40° 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 90 %.
Dangerous mixtures (i.e. inflammable or explosive
gases or vapours), extremely humid air, water va-
pour, 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 (pictures
Compressors that have reached operating temperature may have on the DTE 6 and 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 cooling air entries (E) and
the cooling air exits (F) must have a minimum distance of 8 cm from any obstruction. The discharged cooling air must
not be recirculated.
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 (picture
)
These compressors must not be operated without the standard pressure limiting valve or regulating valve
(optional extra) otherwise the maximum allowable pressure will be exceeded. (see data plate).
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 54
protection and insulation class B or F. The connection diagram can be found in the terminal box on the motor (unless
a special plug connection is fitted). Check the electrical data of the motor for compatibility with your available supply
(voltage, frequency, permissible current etc.).
3. Connect the motor via a motor starter. It is advisable to use thermal overload motor starters to protect the motor and
wiring. All cabling used on starters should be secured with good quality cable clamps.
We recommend that motor starters should be used that are fitted with a time delayed trip resulting from running beyond
the amperage setting. When the unit is started cold, overamperage may occur for a short time.
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.
