YTP Series Turbo Molecular Pump Evacuation Units
The YTP Series are simple high-vacuum evacuation units that consist of an ULVAC turbo molecular pump (UTM Series pump), rotary pump, forevalve, Pirani vacuum gauge and control system. A single unit can evacuate from atmospheric pressure down to high vacuums.
- • Two types are available : Automatic operation type (YTP-SA Series) and manual operation type (YTP-M Series). In addition, 4 evacuation speeds can be selected.
• During power failures, the forevalve closes automatically, and the atmosphere in the rotary pump is vented automatically. The evacuation unit doesn't operate when the power is restored.
• The turbo molecular pump uses fluorine-based oil with a saturation vapor pressure of around 10-11 Pa (at 20ºC), so the atmosphere stays completely oil-free.
• The turbo molecular pump uses high-performance bearings, so doesn't require time-consuming oil changes or bearing replacements.
• YTP-SA models come with interlock functions and external control functions, and can be upgraded with a wide array of functions.
- • As evacuation systems for analysis equipment
• As rough vacuum pumps for accelerators and beam lines
• As high-vacuum evacuation systems for laboratory equipment
