The intelligent operating concept of the CM-RC-01 IQ module, which comes as standard with the ECOLINE+, also ensures optimal efficiency for the oil supply, the oil heater and the new CRII capacity control, which is specially developed for CO2 applications.
The interplay between CRII and CM-RC-01 allows the capacity to be adjusted virtually infinitely between 10 and 100 per cent.
The CM-RC-01 IQ module makes it very easy and inexpensive to integrate the ECOLINE+ reciprocating compressor into a whole host of system configurations.
The IQ module not only improves protective measures and options for monitoring compressors, but also expands their range of applications and thus offers users greater flexibility.
This in turn makes it easier, for instance, to compensate for differences between summer and winter operation. The new capacity control has increased overall efficiency, as the CRII enables a more stable and higher suction pressure.
With the new six-cylinder ECOLINE+ reciprocating compressors for transcritical CO2 applications, BITZER is setting a new benchmark in the use of CO2 as a future-compliant refrigerant.
The ECOLINE+ features a line-start permanent-magnet motor (LSPM), which can be operated directly in networks with 50 or 60 Hertz.
Incorporating permanent magnets has made it possible to significantly increase motor efficiency in full and part-load operation.
This technology has been undergoing testing at BITZER and in selected systems out in the field for more than five years.
Thanks to the intuitive BITZER Electronics Service Tool (BEST) software as well as the monitoring sensors and actuators, which are prewired and preconfigured in the BITZER factory, the compressors are also very easy to configure and service.
