Przedmiotem aukcji jest:
Edwards pompa turbomolekularna
nEXT240D ISO100
Element sprawny, testowany!
Brak kontrolera!
Udzielamy na prezentowany sprzęt 90-dniowej gwarancji rozruchowej!
The nEXT240D is a hybrid bearing compound turbopump available with either an ISO100 or a CF100 inlet flange and has a N2 pumping speed of 240ls-1. nEXT pumps combine our proven bearing technology (oil lubricated ceramic lower bearing with dry permanent magnetic upper bearing), an improved rotor design with a new molecular drag stage to deliver improved pumping speed and compression ratios, and true user serviceability. They feature 24V to 48Vd.c. sensor less motors with a built in drive that is fully compatible with our range of TAG and TIC controllers. They are available pre-set for either 80W or 160W maximum power, the former enabling use with our 100W TIC controllers are also recommended for pumping Argon, but with a longer ramp time to full operating speed.
A basic pump system would require a nEXT240D pump, a TAG or TIC controller, either an air or water cooling accessory and a suitable backing pump.
New technologies employed in nEXT have enabled the pumps to be serviced in the field. An interim oil lubrication change can be performed, where access allows, in-situ, typically in less than 5 minutes with the minimum of specialist tooling. A bearing and oil lubrication service, with minimum disassembly can be performed in less than 10 minutes using basic workshop tools and an Edwards tool kit.
nEXT pumps will advise the user when a service is due and what level of intervention is required. The request for service is by a simple flashing LED sequence on the pumps, and by serial comms notification.
Flexibility is again key as these simple services can be performed either by the end user, on site by an Edwards Field Service Technician or the pump can be returned to an Edwards service hub.
If required, by using remote diagnostics, a user can also interrogate the pump to determine how long it is to the next service, so that a proactive approach to PM can be accommodated.
Features and Benefits
- State-of-the-art rotor design enhances performance to deliver exceptional pumping speeds and compression ratios
- Fully end user serviceable in minimum time without complex tooling or major disassembly...you can do it!
- Compact design with high performance for efficient systemisation
- Compatible with Edwards TIC turbo and instrument controllers meaning you can add up to 3 vacuum gauges without the need of an additional gauge controller
- RoHS compliant and CSA/UL approved
