ACDS - Automatic Chemical Dosing System.

The purpose of a cooling system is to remove heat from heat-producing equipment or processes, and water is the most common medium to transfer that heat.

Experience has taught us that no two industrial cooling water systems are alike. Each system is impacted by the raw water source, air quality, flow rates, metallurgy, temperatures, humidity, operating procedures, and a host of other factors. There is no one size fits all solution - the best cooling water treatment programs are tailored to fit each system.

It is recommeded to install a Mechanical Filtration System and a water treatment program specifically tailored for each installation to ensure high water quality. Both must be used in order to effectively treat the water in a cooling system.

Our treatment programs start with an assessment of the process, water chemistry, cooling requirements and metallurgy in your system, which allows us to determine whether there is a tendency to corrode, scale, foul, or a combination of the three. Our ScaleAwayA912TM water treatment chemical used in various concentrations is effectively used for the reduction of these issues in industrial cooling water systems.

All water treatment chemicals worldwide minimize and control scale build-up within the reticulation, but do not eliminate scale build-up at the heat transfer areas of the system like inside the heat exchangers, oil coolers or condensers heat transfer tubes.
These hot zones need to be Periodically Descaled using a descaler like ScaleAwaySFATM or ScaleAwayBIOTM.

Open Loop Systems – Evaporative Cooling Towers
Open recirculating systems provide the most common form of industrial cooling, continually recycling and reusing the same water for equipment-cooling needs. In these systems, water after it leaves the cooling tower is pumped to industrial applications using heat exchangers, condensers, air compressor jackets, or process reactors.

In this cycle, the water returning to the cooling tower water has absorbed excess heat which is then dissipated by passing the water over a water cooling tower where evaporation and cooling takes place. The cooling tower exposes the heated flowing water to air, causing a percentage (~1-3%) of the water to evaporate, which removes approximately 1,000 BTU’s per two litres of water that is evaporated. This results in cooling of the water that is not evaporated which is then recirculated through the system.

Reusing cooling water results in water savings as well as chemical savings, as the chemistries are retained in the system. However, problems associated with corrosion, deposition, and microbial growths become more severe for several reasons. First, the process of evaporation concentrates the amount of dissolved and suspended solids in the circulating water, leading to deposition. Secondly, the warm temperatures in open recirculating cooling towers are optimum for biological growth. Lastly, the operation of a water cooling tower tends to scrub airborne contaminants from the air which can accumulate in the circulating water, causing fouling and microbial growth.

IPS' water treatment team has experience treating every kind of water cooling tower including natural draft, mechanical, cross flow, and counter flow cooling tower designs.

We can customize a solution for your specific system and work to find savings in the following areas:
    1. Increase heat transfer efficiency by eliminating fouling within heat exchangers with scale inhibitors.
    2. Prevent fouling that results from the precipitation of constituents.
    3. The settling of suspended matter, and microbial growth.
    4. Reduce maintenance and plant downtime with corrosion inhibitors.
    5. Maintain integrity of metal components by mitigating corrosion and pitting, which cause system failures.
    6. Increase Cycles of Concentration with proprietary chemical solutions.
    7. Reduce the amount of makeup water and chemicals required and lower your sewer costs.
    8. Maintain design efficiency in cooling tower water with biocides.
    9. Reduce microbial growth on cooling tower fill resulting in increased splash effect that maximizes air contact and increases evaporation rates.

Closed Loop Systems – Industrial Water Chillers
ScaleAway'sTM expertise with closed loop water systems includes the following:
    1. Chilled water systems used in process cooling water loops.
    2. Chilled water thermal storage systems and ice making equipment.
    3. Hot water systems that generate tempered water for space heating.
    4. High temperature water that circulate water for a variety of uses.
    5. Chilled water systems that generate cold water used to produce cool air for comfort air conditioning.
    6. Chilled water systems used to produce cool air for humidity control.

Most chilled water systems will incorporate an open recirculating cooling water system with a water sump or cooling tower for condenser cooling. Our service technicians have expertise with all associated equipment including evaporative condensers, shell and tube heat exchangers, plate and frame heat exchangers, etc.
