Liquid nitrogen traps remove condensables before they enter the
pump or backstream from the pump to the vacuum system. Water
trapping by the liquid nitrogen cooled stainless steel surface is
complete and permanent.
Liquid nitrogen is added to the reservoir through a fill and vent tube
at the top of the trap. A liquid level sensor from a customer supplied
controller can also be inserted through the tube. Reservoir
capacities, given in liters, are listed in the product tables.
Liquid nitrogen consumption is largely dependent on the level of
vacuum maintained in the roughing line. Other factors such as frequency
of vacuum cycling, ambient relative humidity and gas bleed
also affect consumption. Regeneration is achieved by isolating the
trap from the vacuum system and removing the band clamp to separate
the upper and lower body sections.
