Cos Phi

Founded in 1990, with over 30 years of experience, Cos Phi is a manufacturer of premium power factor correction and power quality equipment and service provider. We can reduce your plant's electricity bill by reducing kVA, and in some cases I^2*R losses. We also protect your equipment from harmonics, transients, and power surges. We manufacture low voltage static and automatic switching capacitor banks, and broadband harmonic filters, with experience in medium voltage too. For delicate operations, ask us about active harmonic filters. We offer an analysis service for the power quality at your site. We can help determine why transformers are overheating under rated load, or why switch-mode electronic devices are failing (VFDs, VSDs, fluorescent and LED lighting, computers, etc.). We can evaluate your existing PFC banks to make sure they are still in working order, and perform any maintenance necessary. We also offer a simple yearly preventative maintenance program too. Let us brush the cobwebs out, and squeeze a few more years out of your existing equipment. See us for individual parts: Line Reactors, de-tuning reactors, PFC capacitors (gas, wet, dry), PFC controllers, magnetic in-rush limiting contactors, fast-switching thyristors, circuit breakers, etc. Contact us for a complimentary hydro billing analysis. Let us show you how you can avoid unnecessary costs on your hydro bill.
