We had availed the services of “NANTECH POWER SYSTEMS PVT LTD” and their service was excellent. Their rates were competitive when compared to others. They have discharged their services in professional manner. We appreciate the timely delivery (at a time, convenient to us) of the battery for the UPS at a very competitive rate.
We purchased UPS from Nantech for most of our systems and they are all working as expected. Their after sales service is exceptional and was the primary reason why we did not have any inhibitions in taking an AMC with them. Keep up the good work!
