For over 40 years now, Bitzer has been offering components suitable for ammonia applications and is offering larger capacities with Bitzer Ammonia Compressor Packs (ACP).

Bitzer Ammonia Compressor Packs are designed to exceed the high efficiency and reliability standards of industrial refrigeration. ACP contain compressors, motors, an oil separator and an optional oil cooling circuit as well as an optional pack of controllers and frequency inverters. Some of their components like the OS.A95 screw compressor and OAHC oil separator were exhibited at Bitzer’s stand at Chillventa  . Designed with a vision of providing the lowest life cycle cost to customer, each ACP can comprise up to three compressors and can achieve up to 3 MW (–10/35oC) of cooling capacity. ACP comes with discharge pressure regulator as standard and a wide variety of options including an economiser.

High efficiency at part-load is ensured by a multi-compressor concept and intelligent capacity control of the compressors. An ACP controller in conjunction with onboard Bitzer IQ technology ensures that the ACP run reliably and efficiently for the given operating condition. The parallel circuit of the dependable Bitzer screw compressors increases operating reliability compared to industrial compressors in the same performance class. Both the controller and the most important sensors are designed with onboard redundancy and proactive control layers to increase system reliability. ACP feature exceptional starting behaviour due to their multiple compressor strategy. The starting current is reduced by approximately one-third when compared with a single compressor pack providing the same cooling capacity. This results in smaller components and lower installation costs. Monitoring the application limits with alarm and shut-off limits ensures maximum reliability.
