Epcon’s regenerative thermal oxidizers are the antithesis to VOC proliferation, with efficiency rates comparable to any available anywhere.
They’re good. Epcon’s Regenerative Thermal Oxidizers, called RTOs in the industry, are designed to be energy efficient to the extreme. They do it primarily due to their ability to achieve high levels of VOC (Volatile Organic Chemical) destruction – keeping processes well below required DRE emission levels. This is thermal oxidation taken to an ideal plateau of excellence, a process of regeneration assisting internal heat recovery so that effectiveness is epitomized.
Multiple energy recovery chambers are used by the RTO in such a way that the integral housings for the ceramic heat recovery media acts as a heat exchanger for the entire system. This type of set-up practically “breeds” an effective efficiency virtually unheard of in our competitor’s RTOs.
The multiple chambers are part of a regeneration principle. They operate under a “swing bed” absorption method, in essence the principle of transfer through multiple beds via the use of flow reversal. Combine this principle with ceramic stoneware, and you get a superb quality of regeneration.
It all begins with the dirty exhaust stream. It travels through the first bed of ceramic media, and the exhaust stream is absorbed within the heat energy stored in the ceramic media mass, in effect, the exhaust stream’s pre-heater. But then a kind of technological “magic” occurs. Once the exhaust stream enters the burner reactor chamber, heat energy is added from the burner to reach the system operating temperature. With the temperature properly elevated, the clean exhaust stream passes unhindered through the second energy recovery chamber. The exhaust stream keeps going. Passing through the chamber, the cold ceramic media mass absorbs the heat energy of the entire exhaust stream, and stores the heat energy for the system’s reverse flow. Depleted, the heat energy of the first chamber begins a classic rotation, directing the incoming dirty air stream through the previous absorption chamber. Result: Clean waste gas spewing nicely through the previously purged chamber.
By the use of an exhaust flow reversal through the ceramic beds, a minimal amount of heat energy is necessary to add in order to maintain the system’s minimum operating temperature. Heat recovery rates of 95% to 97% are suddenly possible. An Epcon-designed RTO is an extraordinarily effective method of ridding VOC contaminants from even the most stubborn flows.
