Domestic hot water systems are relatively smaller compared to CSI-POE systems and typically start at amperage capacity of 5 to 60 amps, the optional use of flow meters (not required in modern CSI technologies), and one to six “active” ionization chamber cells installed in parallel to each other. The number of installed chamber cells is directly linked to the overall daily domestic potable hot water usage load.
Each of the ionization chamber cells should have a dedicated output ionization power drive linked to an automated software-based Programmable Logic Controller (PLC). The CSI PLC should be able to automatically adapts to any potable water conditions that should also be linked to any building management system (BMS). The CSI-DHW solution can are easily installed on either the DHW return or supply side of the loop using standard commercially available plumbing components.
Facilities with multiple separate DHW zones returning to a common mechanical room (yet remaining separate at all times) can install more powerful CSI controllers to lower the overall technology footprint and relative cost without compromising on performance, safety or reliability.
