Bitzer updates product selection software
GERMANY: Compressor manufacturer Bitzer has updated its selection software to include its VariPack frequency inverters, EcoStar condensing units, Ecodesign performance data and new refrigerants.
With update 6.5.0 customers can calculate product performance data with new refrigerants and access technical information to helps users select the appropriate components.
The addition of the external VariPack frequency inverters allows users to configure the ideal combination of compressor and frequency inverter for a variety of applications.
The update also enables system calculation for EcoLine reciprocating compressors in combination with external frequency inverters. In the input field, users can switch this on and adjust the frequency using a slider. As with the compressors of the EcoLine VariSpeed series, here the frequency can be calculated in line with the required capacity or manually adjusted by the user. The appropriate VariPack frequency inverter is then selected in the “Accessories” section.
The software also offers a graphic display of application limits, which is said to make it easier for users to efficiently and reliably select a system for a variety of application cases, even without any special knowledge about frequency inverters.
With integration of the new LHV5E condensing unit, the Bitzer software now contains the entire EcoStar series. The software allows you to confirm the efficiency requirements for individual compact screw compressor units as laid down in the Ecodesign directive and download the corresponding performance data sheet with seasonal COPs.
An extensive range of refrigerants
The 6.5.0 software update also enables system calculation with the four HFO/HFC blends R448A, R449A, R450A and R513A for EcoLine VariSpeed reciprocating compressors and EcoStar condensing units. Bitzer’s double-stage reciprocating compressors can now also be calculated with R448A and R449A, the lower GWP alternatives to R404A and R507A. The update also allows users to configure semi-hermetic compact screw compressors with R450A, R513A, R1234yf and R1234ze.
Oil separators for ammonia applications
The horizontal oil separators of the OAHC series, which have been specially designed for ammonia applications, are also included in the software update. Like the oil separators before them, the OAHC models can also be configured in the Bitzer software in the accessories module, where you can choose between horizontal and vertical oil separators. The software also automatically determines which design is the best fit for the application in question. The OAHC series boasts a triple-stage oil separator and achieves minimal oil carry over rates between 5 and 10 ppm.
The new software can be accessed via the BITZER website (www.bitzer-software.com) or is available for download (www.bitzer.de).
