on page The air cooler is available with a pre-wired connector which
connects directly to an auxiliary port on the controller.
on page A water cooler can be fitted to the pump if the water supply is
suitable.
on A nEXT flange heater accelerates the degassing of the pump to
enable it to achieve lower pressures. It may also be used to
protect the pump from condensation of contaminants.
TAV5 24 V d.c. TAV solenoid-operated vent valve options available for
system venting; these are either normally open (N/O) or nor-
mally closed (N/C).
on Use a VRX fixed orifice vent restrictor to restrict the flow of
vent gas into the pump.
on 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 fittings.
The PRX10 is a modified DN10NW centring ring that filters the
purge gas and restricts its flow rate to the recommended flow
of 25 sccm. A vent port adaptor must be fitted to the purge
port in order to connect a purge restrictor to the pump.
on An interface cable connects the nEXT pump to a PC. Serial com-
mands are then used to control and monitor the nEXT pump.
on The nST2 PC program is PC-based software that can be used
with the nEXT pump either via the serial interface or via the
USB service port.
Enables the use of accessories that do not come prewired with
a mating plug. Cable length is 1.5 m.
The cable extends the distance of the accessory to the pump
and benefits from a right angled plug to accommodate installa-
tion where space is limited. Cable length is 0.2 m.
Enables either a TAV vent valve and a cooling fan, two cooling
on page 113 fans, or 2 TAV vent valves to be operated at the same time. 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.
The EPS 800 can be fitted to the pump or utilized as a benchtop
unit.
