Our Products
Despatchs 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 760C (1400F) to ensure destruction of all VOCs. The oxidation process releases heat and thereby contributes to maintaining the temperature of the oxidizer
Despatch invented the worlds 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.
Despatchs 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.

Features and Benefits :
Direct dynamic jet technology delivers maximum energy for unsurpassed cleaning capability. Electroverts mixed spray technologies can be customized for any cleaning application. The Aquastorm series cleaners are compatible for any aqueous and semi-aqueous based chemistry cleaning process.
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, DriTechs 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.
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. When a lab oven is used for testing materials, stability and repeatability are critical to ensure the oven is not skewing the results. Despatch laboratory ovens are known for their high performance with superior uniformity and consistent results.
Despatch lab ovens feature horizontal airflow which delivers uniform heating across all shelves, whereas most lab ovens utilize vertical airflow. A high-volume fan circulates air through perforated, stainless steel walls to create a constant horizontal airflow across all sections of the oven. These lab ovens provide controlled ramp rates with the capacity to rapidly bring the product up to the desired temperature for shorter cycle times
Despatch lab ovens are easy to clean with stainless steel interiors and smooth door surfaces. They feature sturdy, welded, double-wall construction, thick glass fiber insulation, and heavy-duty door gaskets. Each oven receives a thorough quality and performance test before it is shipped. Heating elements carry a five-year warranty.
Every Despatch lab oven except the LBB series feature the Protocol 3 microprocessor-based temperature and hi-limit controller with a large LCD display. The data-logging functionality enables reporting and analyzing, and data files can be exported via the controller's USB port. You can control the oven from your computer with optional software that also records operating information, including times, temperatures, set points, alarm conditions, and lot numbers. Data is written in an editable form that can be easily saved in an Excel format.
For lab environment processes where minimal contamination is essential, an LCC or LCD Series lab oven offers the highest standard in HEPA filtration. Re-circulated airflow is 100% HEPA filtered for operation at ISO Class 5 (Class 100) or better within the oven chamber.
Typical applications for these ovens include die-bond curing and other semiconductor packaging processes, depyrogenation, sterilizing and drying for life sciences. These units are stackable to save valuable floor space and provide maximum ergonomic efficiency for operators.
This oven is available with inert Atmosphere. Nitrogen (or other inert gas) is injected into the chamber to lower the oxygen level to prevent oxidation of products. A water cooling coil is provided for rapid cooling.
Special design features are required when the oven and/or controls will be located in an area classified as hazardous. This classification refers specifically to an explosion hazard from the possible ignition of dust, vapors or gas in the area external to the oven, and is not limited just to volatiles within the oven chamber. Despatch Class A lab ovens are specially designed to meet NFPA 86 requirements. They include a pressure relief panel, purge timer and exhaust fan.
Despatch's RBC Burn-In Oven offers maximum flexibility for small lot qualification testing, burn-in, reliability testing, and research and development. The stackable oven allows you to run concurrent tests utilizing different temperatures or different cycle times. They are ideal for qualification testing with small lots, because a new test may be started on the second chamber while the first test is still in progress.
