Microclor® Features


The Microclor® onsite hypochlorite generation system (OSHG) incorporates a multitude of patented unique and novel features. The most significant features are as follows:

  1. Passive Hydrogen Removal
  2. Brine Conductivity Control
  3. Full Wave D.C. Rectification
  4. High Velocity Electrolyte Flow
  5. Recirculating Cell Loop
  6. No Internal Cell Baffles or Gaskets

There is no other OSHG system in the marketplace that possesses the same combination of thoughtful design and innovation.

A brief discussion of each individual advantage follows:

Passive Hydrogen Removal

Cells are configured in a vertical format with a recirculation loop on each cell that allows for optimized brine utilization and passive release of the hydrogen gas from each cell. Hydrogen gas is prohibited from passing from cell to cell. The design radically increases operator safety and substantially reduces the possibility of hydrogen gas build-up in the cell and the potential of catastrophic failure. Additionally, by removing the hydrogen immediately from each cell, the configuration eliminates the blinding of the electrodes by hydrogen gas bubbles.

Brine Conductivity Control

Constant current is achieved via a current feedback loop where the brine pump speed is controlled by the system programmable logic controller (PLC). This feedback loop accounts for variations in temperature, conductivity and water flow. The titanium and Teflon impregnated gear pump is attached to a variable speed drive that continually provides a consistent blended electrolyte flow to the cells which maximizes salt efficiency.

Full Wave D.C. Rectification

The D.C. Rectifier design consists of a fully isolated step-down transformer and bridge rectifier. D.C. voltage is fixed with primary taps for ±5, 10.0% voltage correction. D.C. ripple is less than 4.0% with a power factor of 99% or better. Importantly, switching rectifier or phase angle fired SCR voltage correction technology is not utilized on the Microclor® OSHG system as that type of twenty year old technology has low reliability.

No High Current Cell Penetrations

The electrolytic cells consist of thirteen internal bipolar electrodes while the cell outer body serves as both terminating anode and cathode. All anodic surfaces are coated with DSA catalytic coating. The design of the cell precludes the need for wet D.C. cable connections.

High Velocity Electrolyte Flow

The passive hydrogen gas removal design provides a hydraulic lift within the cell and creates a high velocity through the recirculation loop and across the cell plates. This high velocity flow results in a scouring action between the vertically mounted cell plates. The novel self-cleaning feature virtually eliminates the need for acid cleaning of the electrolytic cells and reduces heat build-up.

High Performance Level

PSI's proprietary patent pending vertical cell design provides for a far more efficient generation platform that the industry standard of 3.5 pounds salt and 2.5 KWH per pound chlorine equivalent.

The Microclor® vertical cell produces hypochlorite at 0.8% while consuming less than 3 pounds of salt and 2.0 A.C. KWH per pound chlorine equivalent chlorine.

No Internal Cell Baffles or Gasketing

There are no internal cell baffles, gaskets or fasteners found inside the cell construction. The cells are built with clear acrylic guides that support the internal bi-polar plates and allow for direct visual inspection of the plates -which aids in verifying proper operation. Anode and cathode mono-polar plates are surface mounted to the outside of the acrylic guides.

Cell Maintenance and Replacement

The Microclor® vertical cell design allows for each cell to easily be removed from the cell carrier piping by simply breaking two unions. This makes for simple cell maintenance and or replacement.
