5 Reasons to Filter Cooling Tower Water

Posted by Maurizio Lato, P. Eng., C.E.M. on Jul 6, 2017 11:00:00 AM

Evaporative cooling systems such as cooling towers are widely used for rejecting heat and maintaining temperatures in a variety of applications by directing high flow rates of air counter-currently to water flow.  This, consequently, also makes cooling towers excellent air scrubbers.  Whether cooling towers are utilised to provide cooling for an industrial facility or simple air conditioning in a building, the water treatment program can make a key difference in their operation.

Cooling Tower Passivation Explained

Posted by Micah Thomson on Jun 13, 2017 11:00:00 AM

New evaporative cooling systems, typically cooling towers, ammonia condensers and fluid coolers are manufactured with several options for materials of construction, each with their own benefits and draw backs. Hot-dipped galvanized steel (steel that has been coated with zinc) has become the most common choice for construction as it provides structural strength at a relatively low cost and enhanced corrosion resistance over that of uncoated steel. However, the zinc coating is not well-suited for locations that are in constant contact with water, and requires passive oxidation to be protected from corrosion when exposed to cycled cooling tower water. Passivation is the process by which this zinc layer is oxidized slowly under controlled conditions to produce a passive layer of zinc oxide on the exterior surface of the coating, which provides superior resistance to corrosion.

A Guide to Waterside Inspections

Posted by Micah Thomson on Dec 7, 2016 10:30:00 AM

Performing regular waterside inspections of your critical system equipment is an important part of a successful preventative maintenance program. As we enter the holiday season, many systems may be temporarily shut down, providing a perfect opportunity for waterside inspections.

Visual inspections provide an indication of the overall health of your system and validate the results of your water treatment program. It is crucial to catalog inspection reports to allow you to determine if the current condition indicates equipment status is unchanged, improving or degrading.

How to Prepare for Seasonal Chiller Shutdown and Lay-Up

Posted by Andrew Young on Oct 11, 2016 7:49:40 AM

The leaves on the trees are beginning to change color and temperatures are fluctuating day to day.  We have officially entered the cooling shoulder season.  Temperatures this time of year result in a period of intermittent system operation followed by winter shutdown.  While control of water chemistry is vital to minimizing HVAC system corrosion and preventing deposit formation during the cooling season, additional factors begin to play a critical role during the shoulder season and winter months.

Physical Water Treatment Devices: Understanding and Selecting ‘NCDs’

Posted by Micah Thomson on Jul 20, 2016 11:10:23 AM

The goals of cooling water treatment systems are to minimize corrosion, inhibit scale formation, control biological activity, avoid fouling, and minimize water consumption.  Physical water treatment devices, often referred to as non-chemical devices or NCDs may target all or some of the same requirements as a traditional chemical water treatment program.

Summer is Heating Up - Top 5 Ways to Save on Cooling Tower Bleed

Posted by Patrick Smith on Jun 21, 2016 9:43:21 AM

Cooling towers work by taking advantage of heat lost to the atmosphere when water evaporates. As we’ve just reached the summer solstice, it’s officially peak season to find ways to improve your tower performance. Whether your cooling tower is used for HVAC cooling, cold storage, or an industrial application, reducing the amount of bleed can reduce your water consumption and chemical use

Successful Cooling Tower Start-Ups in 5 Simple Steps

Posted by Mark Bertulli on Mar 15, 2016 8:45:06 AM

Many HVAC evaporative cooling systems are idle or off throughout the winter months, and are often drained to prevent freezing. These extended shutdowns provide excellent conditions for deposits to form and bacteria to grow.
