Used ULVAC RBH-12 #293658151 for sale

ULVAC RBH-12 is an oil diffusion pumping equipment that is capable of achieving high vacuum pressures in high frequency applications. This pump design utilizes a rotary vane system consisting of two oil-circulated opposing vanes and a stationary center orifice that is used to direct the flow of pumped gas. The opposing vanes create a dual action of compression when rotated, along with a pumping action. These two processes create a back-pressure balance, thus allowing for maximum pumping speed and maximum evacuation rates. RBH-12 is designed for high frequencies, making it ideal for precise vacuum processes, such as thin film deposition, mass spectrometry, and high resolution electron microscopy. Additionally, the unit provides a virtually maintenance-free operation, as all internal components are designed to be housed in oil-lubricated cages that move in a balancing machine. The internal design of this tool reduces wear and tear, as well as preventing dirt, dust, and other particles from entering the asset. This model is equipped with an advanced power consumption control equipment, that allows for precise induction control of rotational speed, input voltage, and current. This allows for wide region pumping with great precision. Additionally, the pump features a Gas Ballast System (GBS) that allows the pump to control the intake of air-purity when necessary. ULVAC RBH-12 is designed to handle a variety of gases, including air, hydrogen, methane, air-free nitrogen, and more. The unit comes with a Multi-Mode Rotary selector switch that allows one to select various pumping speeds and options. Additionally, RBH-12 is equipped with overload protection for efficient and reliable operation. Overall, ULVAC RBH-12 is a powerful and reliable oil diffusion pump for precise and demanding applications. The machine is designed to handle a variety of gases, and has an advanced power consumption control tool. This, along with its internal maintenance free design, make RBH-12 an excellent choice for demanding vacuum processes.
