Summary Circulator (Chiller) & Cold Trap

CF301 CF800 CA301 CA801 Water Circulator (Chiller) Cold Trap

Water Circulator (Chiller) Cold Trap Purpose Purpose Supplies a source of temperature Efficiently collects moisture and harmful vapors by trapping them in the container and keeping controlled fluid, typically water, which them from reaching the pump removes heat from a process Benefits Benefits Protects vacuum pumps Keeps water in the condenser at a For oil-sealed pumps, collection of vapors is critical to prevent them from getting into the where they would condense and contaminate the pump’s oil which will eventually cause stable low temperature thereby creat- loss of efficiency or irreparably damage pump ing ideal conditions for collecting the maximum amount of solvent Protects the environment For dry pumps, collection of vapors makes the evaporation system a closed system, preventing vapors from passing through the vacuum pump and into the environment Increases evaporation rate Vapors are collected as a frozen solid and are therefore not condensed inside the vacuum tub- ing, which would slow evaporation
