Foaming in cooling water can occur rapidly, for no obvious reason, and not always predictable by routine system monitoring. Due to the design of evaporative cooling systems, a small amount of foam can be normal. However, in extreme cases, overflowing foam can be cause for alarm. Follow these tips to avoid excessive foaming at your facility.
Cooling towers work by taking advantage of heat lost to the atmosphere when water evaporates. 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.
Aluminum is becoming more common for use in heat transfer applications due to its very high conductance of heat. However, aluminum is highly reactive when compared to other materials such as steel, requiring a specialized treatment program to minimize corrosion of aluminum while maintaining protection of other metals.
In many process and cooling systems, microbiological fouling can present itself as an issue. Microbiological fouling, or “biofouling” is almost always due to the presence of biofilm in the system. In this blog, we will discuss 4 Things to Know about Biofilms in Industrial Cooling Systems.
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
When an un-passivated galvanized surface is exposed to cycled cooling water, which will typically be oxygen-rich and have an elevated pH, white rust will begin to form. Therefore, a passivation program must be implemented as soon as possible after installation before the system sees cycled tower water under load.
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 catalogue inspection reports to allow you to determine if the current condition indicates equipment status is unchanged, improving or degrading.
The leaves on the trees are beginning to change colour and temperatures are fluctuating day to day. We have officially entered the cooling shoulder season.
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.
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. When starting up the
