Coil cleaning video

Watch how steam cleaning removes the dirt and debris from the cooling coils on this air handling unit (AHU). Clean coils significantly improve the rate of air flow moved by the fan blower. After Service-Tech cleaned this AHU, the flow rate across the coils increased by 1200 cfm (cubic feet per minute). This improved its energy efficiency by 78% and reduced the customers’ energy cost by 48%!

Clogged exhaust systems cause air flow problems  

A toilet exhaust system before and after STC technicians removed debris

A large Midwest hospital was experiencing air flow imbalances on the floors of its patient rooms but didn’t know why. It wasn’t until a major remodeling project of the patient rooms that the source of the problem was discovered — the toilet exhaust system had collected a gross amount of debris and contamination. This is not uncommon. Because of the daily linen changes in patient rooms and the amount of activity in a hospital environment, a significant amount of lint and dust collects in toilet exhaust systems overtime and begins to restrict the air flow.

Remove debris and contaminants from cooling towers

This dirty cooling tower shows how nutrients, airborne dirt and debris accumulate over time and attach themselves to the system. Deposits cause blockage and corrosion. This impairs the operating efficiency and can lead to significant damage, even possible failure of the system. When a system is neglected or not cleaned properly, motors burn out. Sometimes the damage is so severe that towers need to be rebuilt.
