The nXQi Dry Multistage Roots Pump minimise gas loss and maintain consistent operation, which is essential in environments where secure gas containment matters. Its dry, dust‑free design supports clean processes, protecting gas purity and system integrity. With strong capability on light gases such as helium‑3 and helium‑4, the nXQ55i delivers stable performance in helium cryostats, dilution refrigeration systems, leak detection setups and other sensitive applications that depend on reliable, repeatable containment.
