The optimised pumping speed and stable high throughput is ideal for the critical Coating, Metallurgy, Heat Treatment and R & D applications.
The smart temperature control and on board sensors ensure minimum load with longer lifetime for heaters and oil. The non-wear components and easy-change heater cartridges ensure extended intervals between service and maintenance.
The Energy Efficiency Controller enables ease of use and operating convenience along with effective monitoring with USB and Ethernet interface. The innovative heating design provides a faster warm up time and enables up to 30% energy savings.
nEXT has been designed to combine all the latest technological advances in turbomolecular pumps offering pump sizes of 55, 85, 240, 300, 400, 730, 925 and 1250 l/s pumping speeds for Nitrogen these pumps provide end-user serviceability and deliver a truly class leading product.
