Water trapping by the liquid nitrogencooled stainless steel surface is complete and permanent.Liquid nitrogen is added to the reservoir through a fill andvent tube at the top of the trap. A liquid level sensor froma customer- supplied controller can also be insertedthrough the tube. Reservoir capacities, given in litres, arelisted in the product tables.Liquid nitrogen consumption is largely dependent on thelevel of vacuum maintained in the roughing line. Otherfactors such as frequency of vacuum cycling, ambientrelative humidity and gas bleed also affect consumption.Regeneration is achieved by isolating the trap from thevacuum system and removing the band clamp to separatethe upper and lower body sections.CF PortsØ TubeISO and KF portsØ TubeATypATypØ BodyØ BodyØ ClampFill and vent tube19.1 OD x 17.3 IDØ ClampBB89Bodyheight89BodyheightHose connectionTrap Nom.
