“MTOWER PLUS” basic treatments.
“MTOWER PLUS” basically operates three main treatments to grant cooling efciency: inhibitor, bleed and biocide.
What is the purpose of inhibitor ?
Inhibitor is a chemical compound that, when added to water, decreases the corrosion rate of a metal or an alloy. It
prevents cooling tower plant to mantain hoses efciency in water circulating system.

What does it mean bleed ?
A method for controlling the amount and concentration of make-up water and chemicals introduced into the recirculating
water of a cooling tower system. A oat operated make-up valve controls the addition of make-up water to the tower. As
make-up water is added to the tower a vacuum is produced at an injector valve which draws chemicals from a chemical
holding tank into the make-up water, thereby allowing precise control of the chemical concentration in the make-up liquid.
Further, a bleed valve is provided which is responsive to the vacuum produced at the injector valve and bleeds a portion
of the recirculating water to waste.

What is a biocide ?
A biocide is a chemical substance capable of killing living organisms, usually in a selective way. They prevent the fouling
of cooling tower water. Cooling tower users frequently apply biocides to the circulating cooling water to control growth
of microorganisms, algae, and macroorganisms. Another very important reason for using biocides in cooling towers is
to prevent the growth of Legionella, including species that cause legionellosis or Legionnaires’ disease, most notably L.
pneumophila. “MTOWER PLUS” can be set to perform also a pre-biocide (biocide activator or pre biocide treatment)
activity.
