Bitzer is now offering a range of compressor units for use with the natural refrigerant ammonia (R717). The Bitzer ammonia compressor packs (ACP) are available with a capacity range of 100 to 450 TR. The modular compressor units comprise up to three compressors. For higher capacities, as many as three compressor packs can be connected (up to 9 compressors) and connected to a single controller, increasing the overall capacity up to 1,200 TR. The company says this is ideal for industrial systems.
