The technology used in today’s HVAC equipment is more advanced than ever before. While this makes temperature control more effective and efficient in commercial buildings and structures, it also presents the potential for new problems. Several of these include interference to telecommunications systems, disruption to programmable logic systems, overheating of components as well as malfunction of the air handler and chiller unit itself.
The cause of these problems may be from harmonic distortion, which is brought into the electrical systems of buildings through the use of variable frequency drives (VFDs) that are installed in air handler and chiller units to control the speed of the compressor motors. These VFDs enable the HVAC system to vary their output to reduce energy costs, but they have a tendency to introduce harmonics into the building’s electrical system.
MTE offers a line of harmonic filters that can help companies who manufacture HVAC equipment. Our Matrix® AP Filter is the most advanced passive harmonic filter on the market today. Most traditional filters work fine at 100% power load, but severely underperform at lower loads. Matrix® AP is the only harmonic filter that adapts to varying loads virtually eliminating harmonic distortion using its patented Adaptive Passive Technology.
The best-in-class MTE Matrix® AP Harmonic Filters can be specified for use on the input of your HVAC to enable your system to meet the IEEE-519 requirements for harmonic distortion, regardless of power load.
