Sircal Rare Gas Purifier - Helium, Neon, Xenon and Krypton
Our new, improved purifier for a new millennium - no need to look further for
the ultimate
in reliable, low-cost rare gas
purification.
Sircal is pleased to announce the
introduction of its new rare gas purifier - the MP-2000. The MP-2000 is a
stand-alone unit for the purification of argon or any of the other rare gases:
helium, neon, xenon and krypton. It offers a compact system for delivery of
purified gas directly to the point of use. The purifier contains two reactive
getter tubes and a molecular sieve drier tube housed in a cabinet for immediate
use. Just plug into the local ac power supply, connect the gas and purge the
lines, turn on the power and you are up and running.
The new design introduces several new features and
benefits. From time to time the user has to replace the getter tubes and the
molecular sieve drier tube when they become exhausted. The new design has been
aimed at making this operation much quicker than before. The getter tubes can
now be removed from the purifier through the top of the enclosure by simply
undoing a couple of gas connections. The drier tube is equally easy to remove
from the front of the enclosure. The entire tube replacement procedure has been
simplified and reduced in time by a factor of 10 compared with the previous
model.
For flow rates up to 10 litres per minute and inlet
pressures up to 250 psig (17 bar), the MP-2000 will remove the impurities, i.e.
oxygen, nitrogen, hydrogen, carbon monoxide, hydrocarbons, carbon dioxide and
moisture (typically present in the range of 30-50vpm) in commercially available
rare gases down to a concentration of less than 1 vpm in total.
The MP-2000 has been designed on a modular basis to
simplify servicing and maintenance by the user. All parts are available as
spares on a quick delivery basis either direct from SIRCAL or from your local
agent.
With over 18 years experience in supplying rare gas
purifiers throughout the world SIRCAL has built up a fine reputation for
reliability and technical excellence. The typical user will find they will need
to replace the getter tubes after about two years use. (Replacements may be
needed sooner if the gas is very impure for example). Replacement tubes are
available at quick delivery and compare very favourably to higher cost
competitive equivalents. The molecular sieve drier tube can have a longer life
as it can be regenerated many times by using the in built regeneration facility.
Easy to use self-sealing plug-in gas connections are
provided to ensure the user cannot leave the purifier open to air contamination
when the purifier is disconnected from its feed gas.
Other features that have been introduced in the MP-2000
include a new electronics design with digital furnace-hours indicator, no loss
of furnace heating due to temporary loss of mains power, relay contacts for
remote indication of purifier status and an alarm system to warn of heater
control failure.
Principle of Operation
The purification system consists of a furnace in which
a titanium getter tube at 700°C removes oxygen and nitrogen by
chemical reaction and a copper oxide tube at 450°C removes carbon
monoxide, hydrogen and hydrocarbons, again by chemical reaction. Finally,
external to the furnace, there is a molecular sieve drier tube operating at
ambient temperature which removes moisture and carbon dioxide by physical
adsorption. The molecular sieve drier tube can be regenerated in-situ by means
of the band heater facility provided.
The furnace temperature is controlled at
700°C by means of a pair of thermocouples which in turn control the
amount of power fed to the furnace heater element via a zero switching
controller and triac. A supervisory alarm circuit in the unit cuts off the power
to the heater element if the temperature of the furnace for any reason rises
above 800°C
