Diagram of Evaporative Coolers Treated with Zeta Rod Systems

Are you inter­est­ed in pro­tect­ing and reduc­ing main­te­nance on evap­o­ra­tive cool­ing equip­ment, sig­nif­i­cant­ly extend­ing the life of cool­er pads and CELdek® media, con­serv­ing water, and elim­i­nat­ing odor and scale buildup?   Zeta Rod® elec­tron­ic capac­i­tor-based water treat­ment sys­tems deliv­er these ben­e­fits and more with a sim­ple  instal­la­tion into the main water line feed­ing one or more evap­o­ra­tive cool­ers.

R. Romo, M. M Pitts and N. B. Handagama. “Biofouling Control in Heat Exchangers Using High Voltage Capacitance Based Technology” ECI Symposium Series, Volume RP5: Proceedings of 7th International Conference on Heat Exchanger Fouling and Cleaning — Engineering Conferences International, Tomar, Portugal, July 1 — 6, 2007

Abstract:
…Four dif­fer­ent appli­ca­tion case stud­ies are pre­sent­ed in this paper in which High Voltage Capacitance Based (HVCB) tech­nol­o­gy was used to con­trol bio­foul­ing. The appli­ca­tions include an evap­o­ra­tive cool­ing wall in a green­house in Oracle, Arizona; a cool­ing tower–condenser appli­ca­tion in Phoenix, Arizona (study per­formed by Arizona State University under a U.S. Department of Energy grant); a cool­ing tow­er sys­tem using reclaimed indus­tri­al waste water at a wafer facil­i­ty in Camas, WA; and a pip­ing sys­tem for a major util­i­ty plant (Tennessee Valley Authority – TVA) using riv­er water.

Biosphere 2: Prevention of Biofouling and Scale in CELdek Wet Wall
Bioshere 2 expe­ri­ences dra­mat­ic improve­ment in the clean­li­ness of wet wall CELdek® media with use of Zeta Rod sys­tems. Expected media replace­ment was unnec­ces­sary and the cli­mate wall can oper­ate at peak effi­cien­cy.
