Turbo pumping station provides fast pump down
Edwards Vacuum
T-station 75 turbo car
Edwards has launched a compact entry-level turbo pumping station that provides users in laboratories and research centres with fast pump down to an ultimate pressure of less than 5 x 10-8 mbar.
At 395 x 350mm, the T-station 75 turbo cart is the smallest in Edwards' range of pumping stations and achieves the fastest pump down of large chambers (greater than 10 litres in volume) for its size.
Edwars claims the T-station can pump a chamber to the required vacuum up to twice as fast as competitive products, thanks to higher-capacity backing pumps.
Arriving pre-assembled, it incorporates Edwards EXT75DX turbo pump with a dry XDD1 diaphragm pump or E2M1.5 oil-sealed backing pump and controller to give a nitrogen-pumping speed of up to 61 litres per second.
The EXT75DX compound turbo pumps feature reliable oil-lubricated ceramic mechanical lower bearings and a dry permanent magnetic upper bearing to provide hydrocarbon- and vibration-free ultra high vacuum.
The cart features a new custom user interface controller, which displays turbo speed as a percentage, making it easier for the user to read with a quick glance.
It can additionally control one active gauge, including APG100 (Pirani), AIM (Penning), ASG (Strain) or WRG (combined Pirani/Penning) and also offers the option of a delayed turbo start, making it suitable for pumping larger chambers.
Users can add a vent valve with a choice of options for automated venting with no user intervention, and the EXT75DX turbo pump is available with NW40, ISO63 or CF63 inlet flanges for greater user flexibility.
