HVAC – Is Drinking water Procedure Needed?

Drum-Kickers, Soap Salesmen…they have been named a lot of things. Drinking water Treatment professionals (possibly the title they want) are all over the place. As a mechanical contractor, we have had lots of knock on our doorway. With most large business structures and industrial facilities in Memphis utilizing drinking water cooling/heating mechanical equipment, this sector is really aggressive, but is drinking water procedure seriously essential? In this edition of Mechanical MattersĀ® I am likely to respond to that incredibly question and talk about various other significant specifics about h2o procedure expert services.

In this edition I want to solution 3 concerns relating to h2o therapy:

Accurately what is h2o treatment and is it important?

How does improper h2o cure company influence mechanical tools?

Are there strength cost savings with water therapy?

1. Accurately what is h2o treatment method and is it needed?

H2o cure describes a process utilized to make h2o more appropriate for a preferred finish-use. These can include things like use as consuming water, industrial procedures, health-related and quite a few other employs.
The purpose of all drinking water therapy course of action is to clear away existing components in the h2o, increasing it for subsequent utilization. (Wikipedia.org)

In the mechanical marketplace h2o procedure is a technique employed to enhance most h2o-primarily based mechanical and industrial procedures, these kinds of as: heating, cooling, processing, cleansing, and rinsing, so that running expenses and dangers are decreased.

Most drinking water treatment systems incorporate drinking water softeners, inhibitors and other chemical substances essential to ‘treat’ the water in get to reach the ideal problems for mechanical use and warmth transfer. Products and solutions applied to maintain proper water problems are generally fed automatically by complex machines right into a chiller or boiler’s drinking water. Water is utilized for both of those cooling and heating in substantial professional developing programs. In most industrial environments drinking water is utilized for cooling manufacturing products or an component to generating a merchandise. How the drinking water is employed will decide what sort of treatment is needed.

Most h2o procedure providers use exam kits and chemical dispensing methods which have designed the use of h2o remedy chemical compounds in chiller, boiler and cooling-tower programs much easier. But attention to information, these types of as how frequently techniques are tested, is vital to system overall performance. The right water treatment method chemistry at the appropriate time is extraordinarily essential for the reason that even small difficulties can build main prices.

Past week I sat down to breakfast with Gary Reynolds and Bob Schubert of Garratt Callahan. They are h2o cure ‘specialists’. Gary and I have labored alongside one another with a number of mutual consumers. Their focus to detail, consumer assistance and broad knowledge of h2o remedy is why lots of structures in the Mid-South are in great fingers with Garratt Callahan. In our meeting they delivered me with some excellent information about the worth of h2o remedy, the results of lousy service and matters to seem for in picking a support company

2. How does inadequate or no services impact mechanical machines?

Improper Water Therapy or no treatment method at all will improve your energy intake and working price whilst reducing your mechanical equipment’s efficiencies and daily life expectancy. A nicely designed and applied h2o remedy application is extremely critical to the operation of any steam boiler, centrifugal chiller and cooling tower. All 3 of the programs revealed underneath make use of h2o for cooling and heating.

Inadequate drinking water cure allows drinking water interact with the surfaces of pipes and vessels which include it. Steam boilers can scale up or corrode, and these deposits will mean additional gasoline is needed to warmth the similar sum of water. Cooling towers can scale up and corrode, but remaining untreated, the heat, filthy drinking water they can comprise will encourage micro organism to develop, and Legionnaires’ Disease can be the fatal consequence. The condenser tubes inside of a chiller and other water cooling tools can also scale up and corrode so stopping great heat transfer. Greater electrical power consumption and inadequate cooling effectiveness is typical final result in inefficient water therapy.

Water procedure can frequently be classified as ‘low-tech’ and unglamorous. Even so, the suitable chemical substances, good chemical feed equipment, and a committed company service provider is important to your mechanical machines and should really be ‘treated’ with top rated precedence.

3. Are there electricity savings with drinking water treatment method?

Cure Benefit: Specialist drinking water procedure can minimize your water, electricity, and upkeep charges substantially. Maybe most crucial of all, it can save you the expense of repairing or replacing tools that’s been ruined by insufficient water treatment method – such as the downtime and shed profits usually associated with solving these kinds of issues.

The examples of drinking water cure ROI (Return of Investment decision) shown under demonstrate how extremely slim levels of deposited content from poorly taken care of water can drive up vitality prices.


Procedure: 1,000 ton chiller

Operation: 12 hours/day, 365 days/year

Charge of electric power: $.10/kWh

Scale thickness: 1/32 inch

Elimination of 1/32 inch of scale saved $15,018 for each calendar year.

Biological Fouling

Program: 1,000 ton chiller

Procedure: 12 several hours/day, 365 times/calendar year

Charge of electrical power: $.10/kWh

Bio-film thickness: 1/1000 inch

Elimination of 1/1000 inch of bio-movie saved $26,834 per 12 months.

“As tiny as 3/16-inch of scale can cause a boiler procedure to use 38 p.c a lot more fuel. The most minuscule amount of dissolved oxygen in the water also suggests a technique could be headed for corrosion difficulties. And even a thin layer of bacterial slime in chiller tubes can noticeably impact warmth-transfer efficiency.”

Wrap Up:

As mechanical contractors we are no strangers to the significance of h2o procedure. Having said that, right after looking into and writing this posting I can assure you that I am much a lot more educated about the requirement and advantage to obtaining a fantastic water treatment software.

In this edition Mechanical MattersĀ®, I talked about 3 vital details about chemical water treatment method. 1st we discovered the definition of drinking water remedy and its use in the mechanical business. Second, we figured out that water remedy is certainly needed, and without it your mechanical tools will experience. Very last we uncovered how correct water remedy will help save energy, and eventually boost your bottom line.
