Air-cooled condensation unit with large-dimensioned condensers, optimised
closed loops and heat transfer in conjunction with high-power fans. These
cost-effective fans with thermal protection shield are well-suited for
electronic speed regulation for an optimal condensation pressure
setting.
Semi-hermetic suction gas-cooled reciprocating compressor in
compact design. The best possible serviceability is provided by means of a
replaceable drive motor, among other things. The compressor stands out due to
its outstanding running comfort and efficient operating performance. The suction
shut-off valve can be rotated by 90° in each instance. Dependable mechanism
lubrication is guaranteed by means of an oil pump which is independent of
rotating direction, as well as a large-volume oil sump. An electronic motor
protection uses PTC sensors in series to monitor the winding temperature and, if
desired, the discharge gas temperature.

Notes
1) | Power consumption of condenser fans included.
|
2) | Tolerance (± 10%)
relates to the mean value of the voltage range. Other voltages and current types
on request
All data are based on voltage rms values |
3) | - The stated value for the max. power consumption is valid
for the adjusted power supply.
- Starting current (rotor blocked):
- Part winding (PW) motors: Winding 1 / Winding 1+2
- Delta/Star (Δ/Y) motors: Δ / Y
- Take account of the max.
operating current / max. power consumption for designing motor contractors, feed
lines, fuses and motor protection switches. Motor contractors: Consumption
category AC3. |
4) | The maximum permissible working current of the compressor
(Imax) must not be exceeded. Take account of the guidelines for use of frequency
inverter (see compressor assembly instruction or selection software).

5) | LP = Low
pressure HP = High pressure |
6) | With liquide temperature at 20°C and 90 % capacity |
7) | Declared dual-number noise emission values are in
accordance with ISO 4871. The corresponding uncertainty to the sound power level
is KWA = 2,5 dB and to the sound pressure level is KpA =
2,5 dB. The values are valid for 50 Hz.
- A-weighted sound power level LWA (re 1 pW), in decibel. To
determine the values, measurement methods of the ISO 3740 standard with
accuracy class 2 or higher were used.
- A-weighted sound pressure level LpA (re 20 µPa), in decibel.
The values are calculated from the sound power level in accordance with ISO
11203: LpA = LWA - Q2 at a distance of d = 1m
or d = 10 m to the reference box.
