The advantages of installing the Horticulture version of the Hydraulic Investigator are the following:
  • This will give you the pump types that we can build for Combi, CombiChem, CombiLineBloc, CombiBlocHorti, CombiLine, CombiPro, CombiProLine and FRE based either on impeller diameter for motor power, or strictly for capacity.
  • With frequency converter equipment installed you can select for 60 Hz on a 50 Hz potential.

The program can be used in several ways:
