Despatchâ€™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, Texanolâ„¢ 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 760Â°C (1400Â°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 â€“ 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 60Â°C wafer or less -based on 508 cm/minute belt speed) Uninterruptible power supply Door switches CE compliance
CARBON FIBER OXIDATION OVEN TECHNOLOGY REINVENTING OXIDATION FOR NEXT GENERATION PERFORMANCE Despatch invented the world’s leading carbon fiber oxidation technology which has become an industry standard. Now Despatch has reinvented the oxidation oven with revolutionary advancements to its pioneering center-to-ends technology. Oxidation is the most critical process step in the production of carbon fiber. It consumes the most energy, has the largest factory footprint, and is the largest capital investment in a carbon fiber line. Any improvement to this step will have a huge impact on the cost and quality of carbon fiber. Despatch’s next generation Split-Zone™ Oxidation Oven with Novariance™ Technology allows you to aggressively push the oxidation rate, reduce oxidation cycle time, and lower the cost of high quality oxidized fiber. Split zone control (patent-pending) provides two discrete thermal profiles for the upper and lower half of the chamber. Separate plug fans and controls allow you to increase the temperature in the upper half of the oven by several degrees, advancing the rate of oxidation of the fiber. Because each oven is now split into two zones, the number of ovens required to properly oxidize the fiber can potentially be reduced. This results in a needle-moving reduction of greater than 50% in annual cost of operation. Novariance™ Technology(patent-pending) provides extremely uniform airflow across the entire width of the tow-band and throughout the process chamber. Patent-pending orifice-plate nozzle structures eliminate the side-to-side and directional variance inherent in conventional nozzle designs. Airflow is also directed into the gap between the center supply plenums which eliminates an area of low to no airflow. Airflow into the gap of the center plenum can be directed as needed to suit the precursor material. The elimination of variance along with split-zone control allows you to push the temperature in the oven, reducing oxidation cycle time by 25% or more. Customer Tests Confirm Reduced Cycle Times - Read the White Paper The Split-Zone™ oven was designed to dramatically reduce maintenance requirements: A sophisticated Pressure Balance System minimizes fugitive emissions to the plant, maintains a stable internal process environment and minimizes energy loss from cold air ingress. Improved heat exchangers in the Split-Zone oven can drastically reduce silica oxide build-up that can affect uniformity. Any maintenance that is still required can all be done from one side of the oven with zero disturbances to the fiber. Removable nozzles in the supply and return receivers mean you never have to enter the chamber for cleaning. The Split-Zone™ oven integrates additional energy saving features and productivity improvements: Hybrid Heating allows you to operate the oven with low cost gas with the assurance of an electrical backup. Patented adjustable end louvers automatically adjust to significantly reduce heat loss and open for fast and easy threading. Rapid cool-down and heat-up capability minimizes time to restart production. With these revolutionary design improvements, oxidation will no longer limit process perfection. With reduced variability, the Split-Zone™ Oxidation oven will deliver higher yields, reduced cycle times and significant cost savings per kilogram of material output.

The DriTech™ Dryer introduces a unique hybrid heating technology that addresses industry challenges associated with faster belt speeds, increased paste VOC concentration and thinner wafers, while providing state-of-the-art metallization drying performance. The dryer is designed to decouple the VOC removal and binder burn-off for a more efficient drying process. Introducing five times the dilution air as conventional furnaces and internal insulation surface temperatures reduces tool contamination. While precise airflow management and a centrally located point-of-generation thermal oxidizer eliminates hazardous waste and facility contamination. Unlike, solely convective or IR drying, which rely strictly on a belt speed and temperature relationship, DriTech’s unique hybrid heating with Smart Tube technology provides a number of heat delivery mediums to efficiently and effectively remove solvent (VOC) from the paste while safely retaining the binder. The low temperature drying capability will ensure that each step in the drying process is separated with no compensation required downstream. Cell performance and efficiency is improved for current and next generation cell architectures and materials.
Maximum versatility for small laboratory spaces If you need an oven for your laboratory, you are most likely looking for a small oven with the versatility to perform simple processes such as drying glassware to complex heating applications that are controlled and recorded.

Drying ovens are used across a range of industries and research laboratories for simple applications, such as drying and sterilizing glassware, to complex processes that require controlled heating and temperature uniformity such as bonding and curing. Drying ovens generally operate from ambient heat to 538°C (1000°F.) Drying ovens may be designed for batch processing or with a conveyor for continuous processing. Despatch Industries builds high performance drying ovens of multiple sizes, processing requirements and temperature capabilities to meet and exceed clients’ laboratory and production applications. Despatch offers options for drying ovens that include HEPA filtration, inert atmosphere and Class A clean process capabilities. All drying ovens feature programmable controls and stainless steel interiors to prevent corrosion. When selecting the right drying oven, critical factors to consider are the heat-up, soak and cool-down times required within your application. Heat-up rates A drying oven should have the capability to heat the part or material to the desired temperature within a specific time. Even if the oven’s heating capability is sufficient, there are other factors that are just as important: Thermal conductivity of the material Size and shape of the material Velocity and direction that the convected air impacts the material’s surface Soak Times Soak time is the amount of time that the material requires once it reaches the desired temperature for the desired length of time. For applications that require precise temperature controls, Despatch Industries offers drying ovens with programmable controls that do not start timing the soak cycle until a set point temperature, either within the product or within the oven chamber, has been reached. Cool-down Times Cool down is achieved when the heated air is exhausted out from the drying oven, replaced by cooler, ambient air. Programmable controls c
Heat treating is the heating and cooling of metals and alloys to achieve a desired physical and mechanical property such as strength, hardness and resistance to fatigue or failure. Heat treating is a precise science that is made more complex by the varying properties of metal alloys. Understanding the properties of the material being heat treated is critical to achieving the desired outcome. Often times multiple heat-treating steps are necessary to produce the properties required for the final product. Benefits of Despatch ovens and furnaces for heat treating: Heat treating often requires processing at high temperatures for extended periods making energy efficiency a high priority. Despatch ovens and furnaces have thick wall insulation, heavy-duty high temperature door gaskets and air that is recirculated through the heater box and back into the chamber for greater energy efficiency. The consequence of uneven heat distribution during heat treating can be disastrous. Choosing a Despatch oven or furnace will ensure you that temperature uniformity will be well within specification. Despatch ovens feature high velocity uniflow airflow, meaning that the air moves both horizontally and vertically, offering exceptional temperature uniformity. Adjustable louvers direct heated air for a precise airflow pattern suited to specific parts. Despatch ovens are available with a gas or electric heater and are available with Class A (NFPA 86) flammable solvent handling capabilities. They are built to withstand the rigors of industrial metal manufacturing with sturdy, welded, double wall construction. Processes performed by Despatch ovens and furnaces: Annealing produces a uniform microstructure and softens metal to improve machinability. (For information on annealing plastics visit our annealing page) Stress Relieving reduces internal stresses in metal caused by cold working or non-uniform cooling. Aging , also referred to as precipitation hardening increases the hardness and strength of metal alloys. Both timing and temperature are critical during the hardening process. Uneven heating can create cracks and other defects, often starting from the corners or edges of the material. Materials that have been unevenly cooled, or soaked, can cause dark, vertical cracks that are irreparable. Tempering is a process used to reduce the brittleness and increase the tensile strength of metal alloys after hardening. Custom Heat Treat Furnaces PNF Inert Atmosphere Oven for Aging Beryllium Copper Despatch received an order for a PNF Inert Atmosphere Furnace for its beryllium copper aging process. A precondition of the order was that a test be performed to confirm that a uniformity of +/- 10℃ at 1000℃ could be maintained. A Despatch engineer was sent to the customer’s facility to perform a field nine-point temperature uniformity test on the Despatch furnace currently in use. The oven was programmed to ramp and soak at three different temperatures and data collected.Â The furnace performed even better than expected with temperature uniformity between +/- 4.3℃ and 6.8℃ (2.4℉ and 3.8℉). The furnace is designed with adjustable recirculating air louvers that allow fine tuning to ensure uniform airflow.
