Designed for simple operation and easy maintenance, our dry ice vacuum traps are ideal for vacuum applications requiring the removal of condensable vapors, or where the use of a liquid nitrogen traps is not practical. Offset inlet and outlet ports for ease of installation and a removable well makes for convenient cleaning and refilling.
Our dry ice traps remove water and solvents and protect oil-sealed vacuum pumps and critical vacuum equipment. Utilizing a dry ice and alcohol slurry, our dry ice traps cool to -75° C, trapping most volatile materials.
Inner Chamber (Dry Ice Slurry)
-Top is removable for cleanout and filling of inner chamber with dry ice slurry.
-Top support lid to be 304 SS. (No acrylic or aluminum lids)
-Inner 304 SS Chamber Reservoir 10.75" OD by 22" height. Inner chamber to hold dry ice slurry at atm.
-Inner Chamber to be glass bead blasted. Inner chamber to include a drain port and connection to outer chamber for drainage.
Stainless steel lid cover will be included on inner chamber.
-Inner chamber (dry ice slurry) volume = 8 gallons.
The inner chamber does not need to be removed. Piping through the bottom of the slurry chamber goes through the outer chamber at
the bottom and a compression fitting allows for the vacuum requirement to be fulfilled.
Outer Chamber (Vacuum)
-Ports on outer chamber to include 2ea 1" NPT vacuum ports with manual valves and 1ea 1/2" NPT vent port with manual valve. Ports at same level.
-1ea 1/4" NPT port with 0-30inHG vacuum gauge,
-1ea 1/2" NPT drain port with manual valve for outer vessel and 1ea 1/2" NPT drain port with manual valve for inner vessel.
-Outer chamber (vacuum) volume = 8 gallons
Outer Chamber to be glass bead blasted. Inner chamber to be removable.
Chamber is helium leak tested to < 10^-8 atm-cc/sec and is rated to vacuum levels of 10^-3 torr or 29.9 inHg.
-The outer chamber has a valve welded in to the bottom, allow for draining without removing the inner
-Outer chamber will also have two each baffles mounted 90 degrees apart running length wise from top to 2" from bottom.
