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

| 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).

| 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.
