RNVS-1200(4320M³/Hour) Big Capacity Vacuum Pumping Set for Transforamer Maintenance

REXON RNVS-1200 Big Capacity Vacuum Pumping Set is a high-performance vacuum evacuation solution specially designed for large power transformer maintenance and on-site vacuum evacuation applications. With a total pumping capacity of 4320m³/hour, this model delivers fast and efficient air removal for large-volume transformer tanks during installation, overhaul, and maintenance.
The RNVS-1200 achieves this high pumping capacity through a powerful vacuum pump combination, consisting of two 1080m³/hour backing (fore-vacuum) pumps and one 4320m³/hour Roots vacuum pump. This optimised pump configuration ensures rapid evacuation, stable vacuum performance, and reliable operation under heavy-duty working conditions.

REXON RNVS-1200 Big Capacity Vacuum Pumping Set is widely used for vacuum evacuation of large power transformers during maintenance, installation, and commissioning.

It is suitable for substations, power utilities, transformer service companies, and large-scale electrical equipment vacuum processing projects where high pumping capacity and stable performance are required.

1. Super-Fast Vacuum Evacuation
The RNVS-1200 can be equipped with an optional synchronous start function, allowing the vacuum pumps and Roots vacuum pump to start simultaneously. Compared with conventional step-by-step starting systems, this design can increase pumping efficiency by up to 40%, significantly reducing total evacuation time..

2.Wide range of vacuum pumping and much better ultimate vacuum degree

Its vacuum pumping capacity is 4320m³/hour, a very big and wide capacity for transformer evacuating. At the same time, its ultimate vacuum can be below 0.1Pa

3. Simple Operation

The standard RNVS-1200 is equipped with a control panel for controlling the operation of pumps, offering simple operation, high reliability, and easy maintenance, making it well suited for demanding field applications. For customers requiring a higher level of automation, the system can be optionally equipped with a PLC fully automatic control system and touch screen interface, providing intelligent control and real-time monitoring.

4. Complete installation and accessories included
The equipment is shipped fully installed and debugged, and comes with the necessary stainless steel vacuum hoses and flange connections, allowing customers to connect and use it directly upon receipt.
