GOELDNER COMPRESSOR have proven themselves for decades in many applications. Now the semi-hermetic compressors of the 2-cylinder-series HS 12, HS 22, HS 32 and the 4-cylinder semi-hermetic compressors HS 34 are optionally equipped with a frequency instead of the terminal box. Because of the special lubricating system of the type HS 12 and HS 22 and the shaft bearing with ball bearings, has a working range from 20Hz to 60Hz without major restrictions with the refrigerants R134a, R404A/R507, R407C in all the above mentioned types of Goeldner-motion series.
Cost savings through:
- extremely simplified startup
- factory pre-programming
- Space in control cabinets is saved
- not shielded wires to the compressor
- a PID controller is integrated in the inverter
- Terminal box is not needed
- Thermistor tripping unit (INT69V) not applicable
- External power filter eliminated
- Reduce the cost of installation
- faster installation
- pressure transmitter connected ready
- optimal performance control of the compressor
