The air c
ooler is available with a pre-wired connector which
connects directly to an auxiliary port on the controller.
Water cooler on page
110
A water cooler can be ed to the pump if the water supply is
suitable.
Flange heater on
page 110
A nEXT ange heater accelerates the degassing of the pump to
enable it to achieve lower pressures. It may also be used to
protect the pump from condensaon of contaminants.
TAV vent valve TAV5
and TAV6 vent valves
on page 110
24 V d.c. TAV solenoid-operated vent valve opons available for
system venng; these are either normally open (N/O) or nor-
mally closed (N/C).
VRX vent restrictor on
page
111
Use a VRX xed orice vent restrictor to restrict the ow of
vent gas into the pump.
Vent port adaptor on
page 111
The vent port adaptor has a 1/8 inch BSP male thread that can
be screwed into both the vent port and purge port, making
them suitable for NW10 ngs.
PRX purge restrictor
on page 111
The PRX10 is a modied DN10NW centring ring that lters the
purge gas and restricts its ow rate to the recommended ow
of 25 sccm. A vent port adaptor must be ed to the purge
port in order to connect a purge restrictor to the pump.
Interface cable on
page 112
An interface cable connects the nEXT pump to a PC. Serial com-
mands are then used to control and monitor the nEXT pump.
nST2 PC program on
page 112
The nST2 PC program is PC-based soware that can be used
with the nEXT pump either via the serial interface or via the
USB service port.
Auxiliary connector
on page 112
Enables the use of accessories that do not come prewired with
a mang plug. Cable length is 1.5 m.
Auxiliary extension
cable on page 112
The cable extends the distance of the accessory to the pump
and benets from a right angled plug to accommodate installa-
on where space is limited. Cable length is 0.2 m.
Auxiliary 'Y' cable
adaptor on page 113
Enables either a TAV vent valve and a cooling fan, two cooling
fans, or 2 TAV vent valves to be operated at the same me. The
two sockets of the Y-cable are wired in parallel so either con-
nector can be used in exactly the same way as the auxiliary
connector on the pump itself.
EPS 800 power supply
on page 113
The EPS 800 can be ed to the pump or ulized as a benchtop
unit.
14.1 Air cooler
The air coolers are available with a pre-wired connector which connects directly to an
auxiliary port on the controller.
