How to Choose Hot Air Drying Oven

Laboratory Oven Principle
A good laboratory oven will last for many years of heavy use day after day, so it's worth putting a lot of thought into selecting the best oven for your needs. This blog post lays out some of the most important features to consider when you're looking for an oven for aggregate, soils, concrete or asphalt testing.

Testing Applications
Construction materials test applications use laboratory ovens to dry materials at controlled temperatures and to heat asphalt materials for handling and testing. It is important to follow test protocol when heating aggregates, soils, and asphalt and avoid high temperatures that may alter their properties. These ovens are used by other industries for applications such as heat-treating, annealing, and conditioning of metals and other materials.

Temperature Range
When matching a lab oven to your applications, maximum temperature ratings are a primary consideration. You obviously need an oven with a maximum temperature at or a bit above the highest temperature called for in your test methods. But models with higher temperature ranges may not always deliver the optimum stability and uniformity performance you need at lower temperatures. In addition, these ovens may use costlier components and can be more expensive to operate.

Chamber Selection
Chamber volume and dimensions are important factors to consider. The chamber needs to accommodate the size and shape of your samples, and you should think about the number of samples you would need to load in at a given time. If you select a chamber size based on a number that is too small, your workflow is hampered. A chamber that is too large means wasted space in your lab and higher operating costs to heat the unused chamber area. Externally, the oven needs to fit available floor space and ceiling clearances, and you must be able to move it in through available door openings. Most oven chamber designed to accept additional shelves and to reposition existing shelves.

Uniformity & Stability
Uniformity in a lab oven is a measure of the consistency of the temperature remains at various points in the chamber. Cold or hot spots affect overall accuracy and may affect test results. All reputable oven manufacturers will indicate uniformity ratings of their laboratory models and some industrial models. Stability is the temperature range over and under the setpoint maintained in the oven by the thermostat or controller.

Energy Requirements
You should know the capacity and configuration of the electrical supply in your laboratory and the power requirements of the oven before purchasing. You may need to plan for electrical upgrades or modifications before installation. For some ovens, amperage draw may be increased over the stated specifications during the start-up period. Gas-fired ovens may also be an option when large capacity chambers or continuous operations are anticipated, and when reduced uniformity can be tolerated.

Ventilation
If fumes from heated samples will be undesirable or hazardous in the laboratory, the oven's exhaust must be vented to the outside. In some cases, the oven can be positioned under a fume hood with adequate capacity, and many ovens have options for direct forced-air exhaust through built-in ports. Some models include options for explosion-proof motors, required when materials or fumes are particularly volatile. Samples with high moisture content may also require ventilation for adequate drying performance. Safe and effective ventilation may require the services of an HVAC professional to design and install an optimal system.

Recovery Time
Opening the oven door frequently to add or remove samples puts an additional load on the system as it tries to make up lost heat. A short temperature recovery time is a desirable performance feature, but it does require additional energy. If your specifications call for a high level of uniformity and accuracy, shorter recovery time will be important to you. Otherwise, heat loss can be controlled satisfactorily by limiting door opening frequency and keeping an adequate sample load in the chamber.

Materials
Many laboratory ovens feature stainless steel interiors and shelf construction to resist corrosion and deterioration. If your materials are not particularly corrosive, you could consider a model that has an interior of plated or galvanized steel as an economical option. Ovens with double-wall construction and good insulation between the chamber and outer cabinet operate more economically, more uniformly, and have a cooler exterior surface for added safety.
