ENERActive Eye On: VFD Retro-Fits Featured Projects Spotlight On EMPOWERactive What’s Next…

ENERActive Eye On
Inverted Duty Rated Motors are able to withstand high voltages and run at lower speeds without overheating. They are primarily dependent on the insulation factor/ motor winding grade.
The Capital Expenditure and Maintenance Costs Associated with VFD Retro-Fits
VFDs are generally recommended for use in motors, which are inverter duty rated. Older motors are typically not “inverter duty rated” and generally are considered to be unable to handle the use of a VFD in a sustainable manner and burn out (due to extreme voltage spikes and respective heat buildup which occurs at lower motor speeds). Many sources state that the time periods for this pre-mature burn out time falls within the 1.5 to 3 year range. According to ENERActive Solutions’ Director of Engineering, Thomas Szarawarski, “considering the amount of factors involved, it’s almost an arbitrary number due to the difficulty of pinpointing.”
Inverted Duty Rated Motor
The time it takes to burn out a motor that is not inverter duty rated and has a VFD is dependent upon several factors including: •Overall motor condition •Use (variable or constant torque) •Variation in motor use •Speed •Distance of cabling between VFD and motor, etc.
There are however, three factors which most engineers do not recognize and are a vital part to this conversation.
With a standard rewind of a motor, you never get back to the premium efficiency, or max efficiency your motor once had. In fact, it gets worse every time, with an initial efficiency loss of 2-3 points and an additional 3-4 point loss per rewind. There are custom rewinds which could potentially increase the efficiency of the motor; however, these are application dependent and vary case-to-case.
When motors are rebuilt and rewound, some shops that do rewind find that it doesn’t pay to design around the standard rewind. Therefore, what you find is that motors that have been rewound previously, are often done so with the “inverter duty rated” retrofit winding.
The insulation system on a 208/230-V motor is identical to that of a 460-V motor (both typically rated at 600 Volts), therefore, the voltage spikes produced by VFDs on 208- or 230-V systems are unlikely to cause insulation damage.
Meaning, motors rated at 208V-230V or less do not have to be “inverter duty rated” to be sustainable for a VFD retrofit.

Featured Projects Power Plant Solutions Presents CO Oxidation Catalyst Project ENERActive Solutions was contracted by Temple University – located in Philadelphia, Pennsylvania – for a CO oxidation catalyst retrofit project. Temple has 20 Caterpillar 3516 natural gas lean burn engines, which are used as peaking units specifically
At full load, each of the
generators are capable of producing 1600 kW at 1200 RPM. The retrofit project included the installation of 20 CO Catalyst units on the outlet of each engine generator. These engines are classified under EPA 40 CFR Part 63 Subpart ZZZZ, RICE NESHAP, (Reciprocating Internal Combustion Engines, National Emissions Standards for Hazardous Air Pollutants). As such, the units are subject to an absolute CO (carbon monoxide) emission limitation of 47 ppmvd @ 15% O2, or a 93% reduction. The units needed CO oxidation catalyst to meet these new stringent requirements. ENERActive was responsible for the complete turnkey retrofit project including the design, material procurement, installation and guaranteed performance of CO oxidation catalysts to bring the generating plant into full RICE NESHAP compliance. The installation of the CO Catalyst units took approximately 10 weeks and relied on the complete cooperation of the Temple and ENERActive teams. The project was completed on schedule, and the final CO testing at the stacks was performed in April 2013 with results indicating that all of the units are now well within the RICE NESHAP emission requirements. Here is what Temple had to say after the completion of the project, and the stack testing results were accepted by the Philadelphia Air Management Services (AMS):

Spotlight On Who’s Who in Energy
President and CEO, Dan Weeden, was featured as part of 2012’s Who’s Who in Energy, an achievement which recognized the industry’s key individuals across the U.S. Recently, he hosted a class on Energy Conservation Strategies for the University of Nicaragua. We want to congratulate Dan for his achievements and contributions on both a national and global level!
Energy Project Engineer: James Coyle PE, CEM, LEED-AP Mr. Coyle joined the ENERActive Team this past quarter as a Senior Project Manager in our New York City Office. With 30 years of experience in both mechanical and electrical systems, Jim’s knowledge and aptitude will not only support, but further advance our energy engineering initiatives and projects. Jim has cultivated expertise in various aspects of commissioning, planning, designing, construction, and operation of energy generating & energy consuming mechanical and electrical systems. Specifically, Mr. Coyle has dedicated the last 6 years performing energy efficiency and design work – having led over 150 energy audits and energy efficiency studies on a wide variety of facilities. Prior to entering the energy engineering field, Jim spent 20+ years in Telecom/Data Centers and critical facilities. Mr. Coyle is an expert in both energy efficiency in data centers and reliability/security of operation. His knowledge and exposure to varying sectors and facilities will prove invaluable to our diverse project portfolio. We look forward to Jim’s versatile skill set and immediate impact he will have here at ENERActive! Take a look at Jim’s kick-off project at the LIRR Headquarters here in Jamaica, NY!

6th Annual First Tee of Raritan Valley Golf Outing
Baltimore Area Council Boy Scouts of America Donation The ENERActive team is proud to support the Baltimore Area Council Boy Scouts of America – one of the largest and most prominent values-based youth development organizations in Central Maryland. The BSA values and believes in a fun and interactive program, which helps youth build a more conscientious, responsible and productive community.
The First Tee of Raritan Valley is a charity organization whose mission is to create a positive impact on the lives of young people by teaching them life skills and positive core values through the game of golf. Currently representing 7 different counties of New Jersey, The First Tee has reached out to more than 1,000 students in the Raritan Valley region. For the first time this year, teams of four will be paired with a student of the First Tee of Raritan Valley and compete in a tournament for “The Raritan Cup.” The golf outing is a day-long event that will include lunch, a silent auction, the golf tournament, and a reception to follow. ENERActive is excited to be sponsoring this amazing cause and look forward to participating in what is sure to be a fun-filled day! Click here to learn more!
Most recently, the BSA honored Jim Foulk, President and CEO of Chesapeake Testing, at Hartford County’s 2013 Good Scout Award Reception, in recognition of outstanding contributions to improve the quality of life in Hartford County, while exemplifying the precepts found in the Scout Oath and Law.
