Does your building have a cooling tower? Cooling towers are an essential component of any HVAC system so it is vital that you understand how to look after your tower correctly. Poorly maintained HVAC cooling towers can lead to outbreaks of Legionnaire's disease and other serious medical conditions. If you do not have a regular cooling tower maintenance regime then you need to develop one now. Here are the top four things that you will need to do to maintain your industrial cooling towers.
Improve your water quality - Maintaining good water quality is essential to the health of the cooling towers and the rest of your HVAC system. Poor water quality can cause multiple further problems and ultimately cause a total system failure. As you will want to keep your HVAC system working well it is always worth investing in proper water treatment.
Clear out the limescale - A common feature of cooling towers, especially those with poor water quality, is the build-up of limescale as a result of evaporation. If you allow deposits of scale to grow then your HVAC system will become less efficient and your unit could start to deteriorate prematurely. By regularly descaling your unit you can improve energy conservation and ensure that your energy costs are maintained at a manageable level.
Check the airflow - If the air doesn't feel sufficiently cold then there could be a problem with your system airflow. It's possible that your fan is not correctly aligned, your fan blades have become damaged or that sludge or other debris has built up within your cooling tower and is blocking the fan. It is a good idea to consider adding a biocide to lower algae and bacterial growth within the cooling tower.
Clear the tubes - Within every HVAC system, there are miles of tubing, all of which are prone to clogging up with scale, slime, algae and even mud. It is important to clear out your tubes regularly to prevent this build-up clogging the tubes and stopping the efficient operation of your HVAC system. It is often advisable to call on the assistance of a professional HVAC engineer to clear your tubes as they will have the skills and equipment to complete this task effectively and to improve efficiency allowing your system to operate as originally intended.
By regularly checking the condition of your cooling towers and the rest of your HVAC system you can ensure that it is operating safely and at maximum efficiency.
