A TANN concentrator is ideal for most process exhausts with a high volume and a low concentration of volatile organic compounds (VOCs) at a low temperature. The design we use can handle up to a 20:1 concentration ratio and up to 95% relative humidity. A concentrator works by sending process air through a large section of the continuously rotating zeolite wheel where 90-97% of VOCs are adsorbed. Once the VOCs are removed, the air passes through the wheel and is sent to atmosphere. A warm air stream passes counter-current through a smaller section of the concentrator where the VOCs are stripped off the wheel. This ‘desorption zone’ cleans the wheel and creates a low volume/high concentration exhaust to feed an oxidizer.
TANN concentrators are designed to maximize efficiency and minimize process downtime through continuous rotation and simultaneous adsorption/desorption of the wheel. When paired with a TANN thermal oxidizer, you can rest assured that you will have a pollution control system built to last for years to come.
TANN Corporation has experience designing and manufacturing turnkey concentrator systems. Particulate levels, temperatures, volumes, and VOC concentration are all considerations that we take into account when designing the optimum system for each customer. Every system is different, and our in-house engineering team will work with you to determine what you need. Whether it is replacing part of an existing unit, the entire installation of a new 100,000+ SCFM system, or anywhere in between, TANN can create a solution for you.
