Detrex SVRM-2-3.5-500 Dual Tank Carbon Adsorber 480V 3Ph W/Precision 90 KW Boiler Make: Detrex Model: SVRM-2-3.5-500 Serial: 72810 Dual Tank Design  Used With Methylene Chloride  Rigging And Hauling Not Included In Asset Sale Price  Located In Texas,USA More Information Upon Request The carbon adsorption unit (CAU) removes Methylenechloride(MC) from the degreaser air emissions by adsorbing MC onto Three carbon beds. Its is approx 99% efficent. The carbon beds are cycled so only two are adsorbing at any one time. The third bed is either, desorbing, cooling down, or idling. The desorb cycle steam strips the MC from a fully adsorbed bed. Once this is complete, the bed cools down and then idles. The time intervals for each cycle are as follows: Adsorb: 6.00 Hrs Desorb: 1.00 Hr Cooldown: 0.25 Hr Idle: 1.75 Hrs A heat exchanger is located behind the CAU near the middle of the bed. Cooling water (city water or a chiller, chiller is not included but we could source from our stock) controlled by a solenoid valve flows through the heat exchanger. The valve is only in the open position when a carbon bed is in the desorb or cooldown mode. The heat exchanger condenses steam laden with MC which then drains to a MC/Water separator. Water mixed with small amounts of MC automatically drains to the CAU wastewater treatment system (WWTS). Reclaimed concentrated MC drains to a receiver tank (behind the first carbon bed) and is then pumped to our degreaser stainless steel stabilization tank next to the still.
