Working
- EST or Electrochemical Scale Treatment System works on the basis of controlled Electrolysis which helps in removal of Scaling and Corrosion, Bio-fouling.
- The reaction tank’s inner wall acts as a cathode.
- The anodes in the tank are made by titanium with nickel oxide coating (Ti.Ni.O). The anodes are resistant to high electrical current and do not dissolve in the water.
- The reaction tank is connected to the cooling tower through a circulation pump.
- An electrical current (DC) is circulated from the anode, through the electrolyte (water) in the reaction tank, to the cathode and produces OH- ions, which causes the pH near the tank walls to rise near 13.
- Near the anodes H+ ions remains, which causes the pH level to decrease near 3.

Salient Features
- Enhanced operational efficiency of the HVAC System
- Reduced equipment downtime & maintenance cost
- One system does it all: prevents Scaling and Bio fouling, eradicates and controls microorganisms, inhibits corrosion and produces free chlorine, prevents the spread of airborne
- Saves water by using the least possible makeup water by effectively increasing the Cycle of Concentration(COC).
- Because the blow-down water are free of chemicals it can be used for irrigation or other internal needs.
Applications
HVAC Systems
Supports cooling water circulation in power plants, ensuring efficient heat exchange and operational reliability.
Cooling Tower
An ELGRESSY in cooling tower HVAC circuit scale water filtration solution reduces scale buildup, improves heat exchange efficiency, and lowers maintenance costs by filtering out mineral deposits.
Water Treatment
An ELGRESSY in HVAC circuit improves system efficiency, extends equipment life, and reduces maintenance by removing bio fouling, scale, excessive blowdown and prevent corrosion in hvac piping
