Our industrial Ovens and intensive Chillers are accustomed to going the extra mile, just like every member of our team. Indexing conveyor ovens use a stop-and-go sequence to move product through them. The industrial oven below is designed for aerospace curing and aluminum aging. Their initial cost is more expensive than electric ovens but have low operating costs. Conveyor ovens can be engineered with electric, natural gas, liquefied petroleum gas, or radiant/infrared heat sources. The most important factor in industrial oven design is its airflow, which must be unobstructed for complete heatsaturation. There are two categories of tunnel ovens: direct gas and indirect gas fired. The food and packaged food industries use batch and conveyor industrial baking ovens to increase the speed of food production. They are fitted with fixed shelf runners and removable heavy duty stainless steel shelves. They have a cooling zone, multiple heat zones, and an exhaust hood. Though industrial ovens operate at close to 1250Â° F, their exterior must be cool to the touch. When the design allows for shipping, 20-ft-long completely assembled sections of the oven can be fabricated. Pressure release is necessary in case of an explosion in the oven. Aging simulates the effects of use, while annealing increases a metals ductility. 3. Other industrial ovens prepare metals for processing, melt metals together, and remove contaminants. Industrial batch ovens process large quantities of products and come in sizes ranging from a few cubic meters to several cubic feet. Below is a brief description of the common varieties of industrial ovens offered by manufacturers. The three basic types of industrial ovens are laboratory, batch, and conveyor. Conveyor ovens are less flexible than batch ovens. Fans, heating elements, and ducts have to be regularly checked for debris. When an industrial oven incorporates convection heating (i.e., electrical or gas), airflow becomes a critical component. In vacuum industrial ovens, drying is at a lower temperature, which is ideal for sensitive materials. The heat produced by industrial ovens creates dirt and grim on its parts. All industrial ovens must adhere to the guidelines established by the NFPA, which has a long detailed list of stipulations, requirements, and regulations for all industrial and commercial equipment. They heat up quicker and maintain temperatures longer than electric or infrared ovens, which adds to their lower operating cost. Engineered air distribution systems that direct airflow patterns facilitates quicker time-to-temperature, transfers heat more efficiently to parts, and ensures temperature uniformity throughout the oven. Listed below are the different sections of the ISO regulations. An industrial oven is designed to heat up to 1,000° F and can be used for many process heating applications. The strength of an industrial oven is in its wall panels and frame, which allows minimal heat transfer to the outer skin. Inform your industrial oven provider how much floor space is available at your plant and make a note of door sizes and other access considerations so they can be factored in to the installation process. Each case resulted in a high performance industrial oven with years of additional useful life. In powder coating, the baking process heats the powder to its melting point to adhere it to a metal piece. Unlike batch ovens, conveyor ovens do not require loading and unloading or heating and cooling, which are labor and energy cost savings. As productive and useful as industrial ovens are, there are considerations that have to be examined when making the decision to use or purchase one. As we like to point out to our customers, the sooner you develop a clear idea of how your thermal processing equipment will fit into your overall process, the more efficient you can make the entire system. Common functions for industrial ovens include drying, curing, testing, and coating of parts and products. Hot water ovens operate on the same principles as steam ovens at a lower temperature range, which is 160o F or lower. Airflow Arrangement The most important part of the thermal process is the heating profile, which describes how quickly your product needs to heat, how long it needs to stay heated, and whether or not it needs to incrementally cool and then re-heat as it is processed. There are two main configurations of industrial … When deciding to purchase a form of heating for production, it is very wise to know the difference between an industrial oven and industrial furnace since people tend to get the two confused. Heat treating includes tempering, aging, stress relief, and annealing of metals at controlled temperatures. Flammable vapors and gases are purged before the heating element is activated. Below is a description of the most common fuels. Temperature Range The easiest way to ensure safe operation of an industrial oven is to comply with NFPA 86 standards. It would be impossible to list all of the varieties of industrial ovens since new ones are being continually developed. Industrial ovens consume a considerable amount of energy and have a significant impact on product quality; therefore, improving ovens should be an important objective for manufacturers. The selection of an airflow pattern depends on the type of industrial oven, which can be with shelves, products hanging, or on carts. Chapters Three and Four, Designing Stoves with Specialized ovens are designed for a single production process. Vacuum ovens control atmospheric pressure in the heating chamber to remove contaminants and provide greater control of treatment processes. Electric ovens are less expensive and do not produce pollutants or emissions. They provide harsh and hazardous conditions for the detection of any problems in a product, especially electrical circuits. The image below is ductwork in a walk-in industrial oven. An additional factor for gas ovens is accessibility. For electricity, consider the operating voltages available at your facility. Indirect gas ovens use a stainless steel heat exchanger heated by gas or propane. Their main selling features are efficiency, precision, and reliability. Industrial ovens operate at extremely high temperatures to heat treat parts, metals, and manufacturing components. Davron exists to be the industry leader in non-standard products engineered to meet the customer's need and unique process. Though laboratory ovens meet the standards of conventional industrial ovens, they are usually designed for smaller part testing or treatment. Below is everything you need to know about industrial ovens. Conveyor industrial ovens do drying, curing, annealing, stress relieving, bonding, tempering, preheating, and forming. The circulating fan pushes air through the burner to the radiant tubes. This article illustrates the delicate relationship between the two. When engineers are designing industrial ovens, there are several factors that they have to consider. Manufacturers use baking and curing as interchangeable terms. General Oven Design & Operation 7. Primary, among those factors, is the selection of construction materials, which include interior and exterior metals, insulation, and the positioning of ductwork for proper airflow. Industrial oven insulation ensures that the oven heats to the required temperature. Types of Industrial Oven. Infrared ovens are preferred for coating and curing processes and applications that require precision and speed. The medical industry requires equipment with precise temperature control for the removal of bacteria, microbes, and viruses. This incremental movement can be used to automate heating and cooling sequences. Upgrading the power supply can be an added expense. Curing ovens create a chemical reaction between a powder and metallic surfaces. An industrial oven is a heated chamber that is used for a range of different heat treatment processes. They are ideal for dealing with combustible products or working with metals like aluminum, which can discolor when heated by gas. They heat-up faster and have a long life. ACE Equipment offers different models of industrial ovens. An alternative to traditional construction methods is an oven module. We strongly recommend speaking directly with a sales engineer to narrow your search and help guide you through the process. The interior chamber is made from heavy duty stainless steel. Unlike electric industrial ovens, gas ovens, which are class A, have to have explosion relief since they are indirect or direct fired.
