ha single-stage compressors
the ha-system - the best solution for deep-freezing!
special features:
- direct intake with external ventilation
- suction gas intake directly into the compressor
- motor cooled by an integrated ventilation unit
this reduces the compressed gas temperature and thus expands the range of application while at the same time increasing capacity (deep-freeze, r22, r404a). at the same time, the compressor is physically separated from the compressor, with advantages particularly in the case of motor damage.

special voltage and/or frequency (on request)
notes
1) 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
pw = part winding, motors for part winding starting
(no start unloaders required)
designs for y/d on request
2) - 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 fuses, supply lines and safety devices. fuse: consumption category ac3.
3) lp = low pressure
hp = high pressure
4) 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 with the refrigerant r404a at the standard rating points according to en 12900.
a-weighted sound power level lwa (re 1 pw), in decibel. to determine the values, measurement bbbbbbs 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 to the reference box.
