Baldwin™- Series SO3 Aerosol Removal System

Specifically Designed to Remove SO3 Aerosol
 

The Perma Pure Baldwin-Series Aerosol removal system is specifically designed for gas sample applications with relatively high SO3 content (>10ppm). The SO3 aerosol removal series has special timing circuits that alternate freeze and thaw the precisely packed heat exchangers. Before an active heat exchanger thaws, the alternate active heat exchanger reaches the -7C set point to ensure uninterrupted operation and no SO3 slippage. This sub zero temperature forms a thin ice layer that captures and removes SO3 aerosol from the sample stream.
 

Operation
 

The two heat exchangers located on the left side of the sample cooler are connected in series. The sample stream first passes through an inactive exchanger used for removing gross amounts of water. The sample then passes to an active glass heat exchanger. The exit dew point from this heat exchanger is controlled to +4°C, thereby reducing he moisture concentration to less than 1%. The gas sample then flows through the gas sample pump where it alternately passes through frozen Kynar® packed heat exchangers, located on the right side of the cooler, then to three-way Teflon® solenoid control valve and finally to the remainder gas sampling system. Condensate is pumped from each heat exchanger by a dedicated peristaltic drain pump head.

Available Options: Acid Safety Scrubber Kit (Part No. 3SCR-004); Water Slip Sensor w/Holder Assembly (Part no. 3KCW-002) Note: Water slip sensor requires 3CCB-018 Alarm board.
