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 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 to the reference box.
