Commercial Air Duct Cleaning System
According to the U.S. Department of Energy, 25-40% of the energy* used for heating or cooling is wasted because air pollutants require an HVAC system to work harder to heat and cool a facility. By having the experts at KNND the buildup of pollutants, your HVAC system will work more efficiently and potentially save you money on heating and cooling costs. Air duct cleaning helps: Improve indoor air quality,Reduce the potential for mold growth,Extend HVAC equipment life, Provide a healthier environment for allergy sufferers, Remove unpleasant odors, Save money on energy costs. We can offer customized services for Ari Duct cleaning.
EDDY Current Testing
KNND’s Eddy Current testing service is a precise inspection of the internal conditions of your air-conditionig and refrigeration equipment’s heat exchanger tubes. These tests help identify minor tube problems and their causes before they lead to serious damage. The process involves sending an inspection probe into the heat exhcnaer tube, the probe creates a magnetic field, which causes electrical disturbances in the tube, called eddy currents. Any tube defects alter the shape of the eddy current field and show up on a plotting scope attached to the probe. Our certified technicians analyse this data to identify pits, cracks, gouges, bulges, worn areas and other tube defects. We then provide you with a detailed report including evaluation data, analysis of the causes of any problems and recommendation for corrective action and long range service solutions. Eddy current test results can also be compared from year to year to help determine rates of tube deterioration for effective predictive and preventive maintenance.
Condenser Descaling
Condensers and even cooling towers require descaling maintenance due to the harsh mineral deposits such as calcium, lime, mud and rust that rob heat transfer efficiency. For instance, most major manufacturers of condenser equipment generally design condensers to operate with a maximum “thermal resistance” or “fouling factor” of 0.0005 inches of buildup. As a result, with only 0.0360 inches (about 1/32”) of deposit corresponds to an increase in energy costs of over 30%. Our technical team can conduct tests to determine the type of cleaning required and suggest the right type of cleaning such as chemical cleaning or brushing depending on the type of scale formation in the heat exchanger. We can further offer solutions to prevent scale formation inside the heat exchanger tubes.
