Distillation Manifold
The Kjeldahl Distillation Systems feature an upper distillation rack with
individual condensation columns, these are connected together by a common
manifold (6 columns per manifold). The tap water inlet and outlet connections are
3/4" NPT and the supply line should be minimum 1/2" ID for proper water flow
and heat removal capacity through the condensation columns (6-8 gallons/23-30
liters per minute).
The plumbing line for the outlet of the distillation manifold must be free of back
pressure to avoid flow restriction of the cooling water. If the Kjeldahl Distillation
System is equipped with the Acid Fume Water Aspirator Exhaust System option,
the distillation water drain should not be connected to the aspirator drain, unless
provisions are made to handle the larger water volumes without water backing up
over the aspirator vent line.
Water discharged from the distillation manifold is not acid contaminated and
standard drain lines may be used for its removal.
