Mirus International Inc.

Corporate Profile

Since 1991, Mirus International has been a supplier of specialized power quality products to reduce or eliminate harmonic problems and save energy in electrical power distribution systems worldwide. As true innovators, our unique approach to harmonic mitigation has produced many patented designs useful in addressing the problems associated with harmonic generating non-linear loads such as Adjustable Speed Drives (ASDs), both AC and DC, personal computers and other power electronic devices. Markets include Oil & Gas (drilling and pumping applications), Water/Waste Water, Chillers and other HVAC equipment, Marine vessels, Data Centers (servers and cooling equipment), Telecommunications and Broadcasting facilities.

Our strength is in our technical expertise as problem solvers. Principals at the company have been successfully resolving difficult power quality problems for decades. This includes the first application of a zero sequence harmonic filter for the removal of heavy 3rd harmonic current in a high tech manufacturing facility in 1986. Our Neutral Current Eliminator (NCE) is a refined version of this device.

We are the original inventors of Harmonic Mitigating Transformers which combine low zero phase sequence impedance with phase shifting to treat harmonics generated by non-linear loads. This strategy not only improves power quality by reducing voltage distortion and flat-topping but also saves energy by lowering the harmonic losses within the transformer and upstream distribution system. In addition, unique low loss core configurations are used to provide environmentally conscious customers with both sustainability and financial benefits.

With the introduction of our revolutionary LINEATOR Advanced Universal Harmonic Filter (AUHF) in 1999, we soon captured a major portion of the market for premium harmonic Adjustable Speed Drive solutions. These passive harmonic filters are proven to provide the best performance, highest efficiency and highest reliability of any passive solution on the market. In addition, they do not introduce the high frequency switching harmonics that alternative parallel active harmonic filters and active frontend drive solutions do. Often these higher order harmonics cause bigger power system issues than do the lower frequency harmonics these devices are designed to reduce. The Lineator AUHF is now the solution of choice for many of the major ASD manufacturers and is being specified by many consulting engineers worldwide.

Our one-of-a-kind Harmonics & Energy (H&E) Lab offers the ability to fully test products under ‘real world’ non-linear load conditions. Through performance validation in the H&E Lab, our customers can be assured that our promised power quality improvement and cost saving energy reductions can be fully realized. And our free SOLV computer simulation software can be used to evaluate and compare solutions for treatment of harmonics in specific customer applications.

At Mirus, we are motivated by the challenge of finding solutions for the most difficult of power quality problems and to design the highest efficiency transformer and harmonic filtering products on the market. In this way we expect to continue our steady growth, one satisfied customer at a time.
