Murrell and Brad Ramsey formed RSI in 1978. RSI’s primary business focus until 1984 was water treatment chemicals, water softeners and filtration. Whenever RSI personnel were asked about NON-CHEMICAL methods to treat cooling towers and boilers, the answer was that they had little or no validity.
In 1984, Professor Tom Murray, Jr. of the University of Louisville’s Speed Scientific School contacted RSI about an IONIZATION PROCESS he was working with to control scale, corrosion and bacteria in systems utilizing water as a heat transfer. This technology was a refined usage of impressed current cathodic protection, the same technology that had been used in the shipping and pipeline industry for over 100 years.
RSI tested the process under controlled situations and found that indeed the process controlled scale, corrosion and bacteria much better than conventional chemical treatment. Since 1985, this ionization process has been the main product offering of RSI. Today we provide environmentally safe water treatment in over 2,500 systems throughout the eastern half of the US. This service is provided through a combination of direct sales, trained dealers and HVAC service companies.
The following test illustrates how Ecology Cells™ prevent and remove scale from the heat exchange areas of cooling tower and boiler systems.
The basis of the test is the fact that all scale has a definite crystalline structure and is held together by small electrical charges within the crystals. By disrupting these electrical charges, the Ecology Cells™ prevent scale crystals from forming. In this test sodium chloride (salt) is used because of its easily recognizeable cube-shaped crystals.
To begin the test sodium chloride is dissolved into a beaker of distilled water. In each photo, droplets of the salt water are placed on a slide and evaporated. Photo (1) is untreated saltwater magnified 20,000 times. The cube crystalline structure is clearly visible.
An Ecology Cell™ is placed in the beaker of saltwater and photos (2), (3) and (4) are taken after five minutes, ten minutes and fifteen minutes of treatment.
In photos (2) and (3), also magnified 20,000 times, the cube crystal structure is initially still recognizeable although the structure is beginning to break down. In photo (3) the cubes have broken down into fern-like structures.
In photo (4), magnified 40,000 times, the particles have become very small and in fact are rejecting each other.
These particles reject each other through the system harmlessly until they are discharged through the normal bleed or blowdown. This same process will slowly dissolve existing scale at heat exchange areas. This prevention and removal of scale saves thousands of dollars in energy and maintenance costs.

Ecology Cell™ Operational Specifications
Ecology Cell™ water treatment cell from RSI (800) 488-5879
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.)
RSI shall determine the exact number of Ecology Cells™ required per system based on factors including water quality and system load.
A person trained to RSI standards shall clean the Ecology Cells™ on an as needed basis and test the system water. 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 reported in a manner agreed to by customer. While Ecology Cells™ are in each system treating the water daily, depending on the water quality and type system, visits to check system and test water are typically within a 60 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. Other tests may be pertinent on a case by case basis, depending on the makeup water quality.
The cleaning duties include:
Clean Ecology Cells™ and racks thoroughly.
If applicable, check system bleed/blowdown for proper operation.
If applicable, visually check for Algae. Environmentally safe treatment approach for Algae control as needed and agreed to by customer.
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.
As agreed to by customer, verbal and written report to customer, maintenance contractor, etc.
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.
