Ecology Cell™ Operational Specifications
Source:
Ecology Cell™ water treatment cell from RSI (502) 376-0452
Function:
Ecology Cell™ program controls scale, corrosion and bacteria in any system using water for a heat transfer when applied properly. (cooling towers, chillers, boilers, closed loops, etc.)
Sizing:
One 36" cell shall be provided for each 100 gallons per minute of recirculated cooling water, or each 75 horsepower in a boiler. RSI shall determine the exact number of cells required per system.
Maintenance:
A person trained to RSI standards shall clean the Ecology Cells™ on an as needed basis and test the system water on a frequent, typically monthly, basis. Cleaning shall include the Ecology Cells™ and the supporting racks. Silver cells should be cleaned thoroughly, taking precaution not to damage the silver finish. Water tests shall be performed and written in a log book. Depending on water quality and operating parameters of cooling towers and boilers, return service visits typically fall between a 25 to 45 day window. Some systems, such as closed loops, may only require service every six months. The water tests shall include 1) conductivity 2) pH 3) dissolved iron. A system review shall be provided to the customer.
The cleaning duties include:
Clean Ecology Cells™ and racks thoroughly. Check system bleed/blowdown for proper operation. Check for Algae. Shock, chlorine or bromine floater, or a non chemical treatment agreed to by customer, as needed. Check for mud/silt buildup around cells. Maintenance contractor shall clean the mud/silt buildup from system if buildup is within 1" of the cells. Verbal and written report to customer, maintenance contractor, etc.
Electrical Ground:
The customer/maintenance contractor shall be responsible for checking the electrical ground connections on all drive motors coming in contact with the water, including all fan and pump motors. A "WYE" is acceptable. A "DELTA" (3 wires or a multiple of 3 wires) is not acceptable. A "DELTA" ground will induce a small current through the water that will lessen the effect of the Ecology Cells™. With a "DELTA" ground, a separate 6 gauge or larger solid copper wire must be installed from the motor mount(s) to a grounding rod in accordance with the local electrical code.
