vacuum ovens, with custom options available. These ovens
ensure accurate temperature control and fast heat-up times,
making them perfect for drying, curing, sterilizing, and more.
Reliable and precise, Despatch benchtop ovens are trusted
for superior performance.
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.
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.
Industrial ovens are heated chambers used in the production processes to enhance
product quality, strength, hardness, and longevity. They are available in a range of
sizes, configurations, and temperatures.
An Industrial Oven is used in a wide variety of industries, including manufacturing,
chemical processing, healthcare, transportation, and electronics. Common
applications 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.

processing needs.
Annealing – Heating and slow cooling
in order to toughen and reduce brittleness.
Drying – Removal of moisture (water that is not chemically
bound).
Sterilization – Eliminates or kills all forms of life present
on a product.
Burn-in Testing – Process of stressing components to test for
failure.
Aging – Rapid Weathering of Metal to achieve a stable surface
condition. Curing – Controlled heating of a substance to promote or control a
chemical reaction.
Baking – Heating to a low temperature in order to remove
entrained gases. Dehydrogenation – The use of dry heat at high temperatures to
destroy pyrogens.
Heat Treating – Changing metal properties such as hardness,
strength, flexibility, and stress resistance

DETERMINE
WHETHER A BATCH OR CONTINUOUS MODEL OVEN WILL WORK BEST
Batch Ovens
Batch Ovens
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.
Continuous Ovens
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 of each part in high-volume
application, 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.
STEP
3 CHOOSE
THE BEST CHAMBER SIZE TO SUIT YOUR PROCESSING NEEDS
Lab or Benchtop Ovens
Because of their small, convenient size, these ovens are used for laboratory
test and development applications, as well as production applications that
require small batch loads. These ovens range in chamber size from 1 cubic foot
to 27 cubic feet (28 to 764 liters).
Cabinet Ovens
This size is referred to as a reach-in oven because they are ergonomically
designed for easy loading and unloading. Cabinet ovens are floor mounted, very
efficient in terms of footprint and typically range in size from 4 to 35 cubic
feet.
Walk-In and Truck-In Ovens
Large batch ovens can accommodate a wide variety of specific product/process
needs. They are suitable for loading by fork truck or manually. Typically
truck-in ovens ranges from 52 to 210 cubic feet, and walk-in ovens start at 360
cubic feet and larger.

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.
STEP
5 KNOW
HOW CRITICAL TEMPERATURE UNIFORMITY IS FOR YOUR PROCESS
9 Point Uniformity Survey
Before implanting a critical thermal processing step you need to confirm that
the oven you are using is delivering the temperature uniformity required for
your process.
A nine-point uniformity test that measures temperature in every corner as well
as the center of the oven will ensure that the temperature throughout the oven
remains constant.
STEP

CHOOSE THE
BEST AIRFLOW FOR YOUR PRODUCT LOAD
Consider how parts can spaced with each type of
airflow to ensure optimal airflow through or around all parts of the load.
