    Man your spelling is horrible. The company I worked for the past 4 years was a DB dealer and I have worked on many of them. DX and Flooded but mostly flooded chillers with the vertical screw compressors.. That model number that you are giving out does not ring any bells. I guess that it might be a new system or a DX system that I have not seen. What is your problem anyways?

    It's not his spelling, it's his putting a question and answer together., maybe not American decent,?

    I searched newsletters manuals compressors for loading and unloading de slide
    Both the units of the system 2 will not exceed 15% FLCP systems 1 to 100% in FLCP

    Question

    That is the FLCP???
    Would have to operate at 100% both FLCP??
    I have to make a change in program for 100% load FLCP systems # 2?
    Will pressure drop graphs for this unit and review appropriate galonajes
