Nearly every process in hospitals demands high quality of water. 

Rising water and wastewater costs along with sustainability regulations make water use efficiency a must.  Having a continuous supply of treated water is essential for hospitals, something we understand.

Elgressy’ systems provide a reliable and cost-effective solution for the following applications in hospitals: 

Cooling Tower treatment – EST:

EST provides a comprehensive and effective solution to the problems
associated with cooling towers, namely scale, corrosion and


  • Cost effective and reliable- rapid return of investment.
  • Generates significant water savings
  • Eliminates the need for expensive and harmful chemicals.
  • Very low life cycle cost and electricity consumption.
  • Reduces maintenance, shut down time and labor costs.
  • Simple retrofit with small footprint.

Corrosion Prevention – ECP:

ECP is an effective and innovative electrolysis technology developed to protect the inner surfaces of hot and cold-water pipes and tanks against corrosion and scale.


  • Rapid results - Immediate prevention of new corrosion-accumulation and stoppage of “red water”.
  • Versatile – Effective in hot and cold-water systems, water tanks and all pipe composition.
  • Safe drinking water - no adverse effect on water quality or taste.
  • Low operational cost - low energy use and low water consumption rates.
  • Cost effective – low energy consumption, prevents blockages and equipment damage.
  • Very low life cycle cost and electricity consumption.
