VOC THERMAL OXIDIZER

Despatch’s VOC Thermal Oxidizer was designed to eliminate 99% of Volatile Organic Compounds (VOCs) from gasses exhausted during the drying step of solar cell manufacturing. The solar cell manufacturing process creates unwanted environmental pollutants which are byproducts of the drying process, and contain the non metallic ingredients found in the paste material such as ethanol, Texanol™ and terpineol. These pollutants can condense inside facility ductwork and create hazardous conditions. Destroying the VOCs using the Oxidizer eliminates the need to collect and dispose of this waste in a separate process. The exhaust exiting from the VOC Oxidizer contains only CO2 and water vapor. In industries that emit VOCs and have established pollution control technology criteria, Thermal Oxidizers satisfy Best Available Control Technology (BACT), Maximum Available Control Technology (MACT) and Lowest Achievable Emission Rate (LAER). The operation of the VOC Thermal Oxidizer is based on the principle of combustion which is the most commonly used method to control emissions of organic compounds and is used in a variety of industries. Combustion systems are simple and have very high destruction efficiency. The VOC Thermal oxidizer maintains a temperature of 760°C (1400°F) to ensure destruction of all VOCs. The oxidation process releases heat and thereby contributes to maintaining the temperature of the oxidizer Standard Features: Designed for high-speed, high-capacity solar cell manufacturing lines Eliminates VOCs as close to the point of origin as possible Electric (no need for gas or open flame, no NOx generation) Runs off of furnace power (with soft-start software) Best in class (99% or better) destruction of VOCs: Odors – 100% elimination of odor 99%+ destruction of particulate matter and VOCs (Volatile Organic Compounds) Exhaust contains only CO2 and water vapor Meets legal requirements regarding the capture or destruction of VOCs including TA Luft regulation of Germany Eliminates need for handling and disposal of waste product collected in VOC condensers Fits on top of CDF dryer - no additional footprint required Options: Edge contact belt Belt stand-offs Wafer cooling (For 60°C wafer or less -based on 508 cm/minute belt speed) Uninterruptible power supply Door switches CE compliance
