Industrial ovens are heated chambers used in production processes to enhance product quality, strength, hardness, and longevity. They are available in a range of sizes, configurations, and temperatures. Industrial ovens are used in a wide variety of industries, including manufacturing, chemical processing, healthcare, transportation and electronics, industrial ovens operate at ambient temperatures from slightly above 250℃ (676℉) to 538℃ (1000℉).
Common applications for an industrial oven include annealing, curing, drying, baking, aging, and heat-treating parts and products. They can also sterilize medical instruments, heat treat 3D printed parts, compact and materials, burn-in test parts and products, and remove pyrogens from pharmaceuticals. In addition, industrial ovens activate adhesives, meld materials, shrink, preheat, melt, laminate, and bond materials thermally.
Despatch is a leading industrial oven manufacturer with a wide range of industrial ovens and furnaces designed to accommodate a variety of load sizes and production volumes. Despatch is known for tighter temperature tolerances, higher yields and consistent, repeatable results. Our industrial ovens deliver invariable, uniform temperature for as long as the oven is in service thanks to its solid build quality and design. We also go to great lengths to move our products to market faster, providing short lead times and quick delivery.
For thermal processing applications where load size or production volumes vary substantially, batch processing is the optimal solution. Our batch oven line includes forced convection ovens, pass-through ovens, inert atmosphere ovens, HEPA filtered ISO Class 5 clean room ovens and Class A ovens.
For high-volume, repeatable thermal processing, continuous operation may be the optimal approach. Despatch continuous ovens offer conveyor widths from 46 to 91 centimeters with electric or gas heat.

Despatch laboratory ovens are high-performing and built from corrosion-resistant materials. Our standard line of benchtop ovens includes forced convection ovens, high-performance laboratory ovens, industrial production ovens, Class A ovens, stackable clean process ovens, test ovens, burn-in ovens, and benchtop furnaces. Our ovens are versatile enough to handle a wide range of applications and provide exceptional heating accuracy, temperature uniformity, and process
Industrial Cabinet Ovens & Furnaces (Reach-in Ovens)
Despatch’s cabinet ovens are designed for easy reach-in loading and unloading. Our standard line of cabinet ovens includes forced convection ovens, lab ovens, industrial production ovens, cabinet furnaces, and clean process ovens. They also include polyimide curing ovens, catheter curing ovens, paint sample curing ovens, inert atmosphere ovens, and top-loading ovens. These batch ovens provide a small and efficient footprint and a wide range of chamber sizes.
Industrial Walk-in Ovens and Truck-in Ovens
Suitable for loading manually or by forklift, these batch ovens are ideal for a broad range of applications including aging, bonding, curing, drying, baking, heat treating, annealing, and stress-relieving. They feature industrial ruggedness, excellent process control, and dependable operation. Our standard line of truck-in ovens have chamber capacities ranging from 52 to 952 cubic feet and temperatures from 650°F to 1000°F.
Industrial Conveyor Ovens for Continuous Processing
Despatch conveyor ovens are versatile, reliable, and achieve superior air temperature uniformity on all interior parts due to high-volume, vertical down airflow. Their unique belt design is ideal for large quantities of similar workpieces being processed. Options include Class A models designed explicitly for flammable solvents and a HEPA filtered model for applications that require Class 1000 cleanliness.
Selecting the Right Industrial Oven For Your Processing Application
DEFINE YOUR APPLICATION
The first and most important step in finding the right piece of equipment is to determine what function your equipment needs to serve. The scope of thermal applications is endless and can range from common to complex.
You should also consider the environment that the oven needs to operate in. If you are using the oven in a clean room you will need a clean process oven. If you are using the oven in a laboratory for testing, you will most likely be looking for a small oven with the ability to document test results
DETERMINE WHETHER A BATCH OR CONTINUOUS MODEL OVEN WILL WORK BEST FOR YOUR PROCESS
For applications where the load size or production volumes vary substantially, batch processing is a good approach. Batch ovens are also ideal for situations that require a high degree of flexibility in terms of process variables such as temperature or dwell (soak) time.
Where a large quantity of similar product pieces are processed, continuous operation may be the optimal approach. Continuous ovens help ensure consistent thermal processing times for each part in high-volume applications, such as manufacturing electronic components or automotive parts. Continuous ovens may also allow several discrete processes to be combined, reducing material handling and increasing throughput.
CHOOSE THE BEST CHAMBER SIZE TO SUIT YOUR PROCESSING NEEDS
Chamber size depends on the size of the product or parts, the number of products in each batch, and the number of batches required per day to meet production requirements. If the interior space is too small, insufficient space between parts results in poor performance. If it is too large, space, time and energy are wasted.
When using forced recirculating airflow, parts benefit from spacing, but the oven can be loaded more densely vertically because airflow is distributed along the entire side wall. Parts should be kept 2-3 inches (5.1 - 7.6cm) from the oven walls.
CONSIDER YOUR TEMPERATURE REQUIREMENTS
When considering the temperature requirements for your application, first note the minimum and maximum operating temperatures required. Additional temperature considerations include:
- The required dwell time at temperature, and the overall cycle time.
- The type and amount of product load. The oven design will need to have sufficient heating capacity to bring the product to the desired temperature within the specified time.
- Whether the heat-up rate needs to be controlled or if the product can be allowed to reach temperature as quickly as possible.
- Any specific cool-down requirements
KNOW HOW CRITICAL TEMPERATURE UNIFORMITY IS FOR YOUR PROCESS
Uniformity is critical to consistent heat processing results. It is typically expressed as the maximum difference between the highest and lowest temperatures in a chamber at a specified setting. For example, ± 2C° at 200°C, as tested in a 9 Point Uniformity Survey.
FACTORS THAT INFLUENCE TEMPERATURE UNIFORMIT Y INCLUDE:
- Cold air stratification (cold air entering chamber)
- Accuracy and response speed of controller
- Heat loss through oven walls or door/door seal
- Placement of workload
- Ability to direct the air through the chamber
- Volume and weight of products being processed
CHOOSE THE BEST AIRFLOW FOR YOUR PRODUCT LOAD
In most cases a forced convection oven with recirculating airflow will provide the best distribution of heat and significantly speeds the time-to-temperature and heat transfer to parts. Temperature uniformity and performance depends on a fan design that directs air to all areas of the chamber.
Your product and how it is loaded will determine what type of airflow will provide uniform distribution of heat to all parts of the load. For instance, if your product is to be loaded on a solid tray, horizontal airflow is the best option.
Consider how parts can be spaced with each type of airflow to ensure optimal airflow through or around all parts of the load.
