Rack controller NA

  • General characteristics

    Rack controller is a line of controllers designed for the more complex and advanced systems. The availability of inputs and outputs covers the requirements of the most sophisticated compressor racks in terms of the number and the function of the required control algorithms. The control software in six languages, compatible with the different sizes of hardware, satisfi es both the most common control requirements as well as the more advanced applications. Possibility to separate compressor and fan control on one single user interface, with local network connection between the controllers. Drastic reduction in the cost of electrical connections to remote fans. Modulating capacity control using special inverter outputs for the compressors and/or inverter/phase control outputs for the condenser fans. Operation with fl oating condensing and evaporation* pressure to increase the effi ciency and the performance of the compressor racks. * requires a compatible CAREL supervision software.
