BITZER REFRIGERANT RULER is an Android app designed to make it easy and fast for users to determine refrigerant data. The app contains all common refrigerants, including key fluid properties, safety group information, global warming potential (GWP), ozone depletion potential (ODP), and information on the choice of oil type for the compressor. The app also provides additional information on refrigerants, links to relevant online documents, and other information displayed under the "More..." option in the menu bar.

The tool features an intuitive user interface, allowing for easy and accurate temperature-to-pressure conversion, while allowing easy use and switching between different metric (SI) and imperial (IP) units under the "Settings" option. The app contains data and information on more than 100 natural and synthetic refrigerants, which can be preselected by filter functions under the "Search" option. The app also provides information on previously used refrigerants for comparison purposes and practical use in service and operation of older existing systems.
