In this week, we just finished the production of our big model transformer oil purifier ZYD-200, which treatment capacity is 12000liters per hour. And for every REXON oil purifier, before its delivery, we will make strict quality inspection in our factory, and the machine will be tested in factory at least half a day with our engineer's professional operation and inspection. And for this machine too, it was tested in factory for about five hours smooth running, as usual, this equipment is successfully tested, and allowed for the delivery.
