Large Vacuum Oven

Large Vacuum Oven

The DOV70, DOV80, and DOV100 large vacuum ovens are suitable for large samples and higher-volume materials, including electronic components, chemical materials, battery materials, powders, adhesives, degassing, vacuum drying, and low-pressure heating. Compared with benchtop vacuum ovens, their larger chambers support R&D, quality control, and factory processes that require larger samples, greater throughput, or process-oriented testing. Select a model based on sample dimensions, load, vacuum requirements, operating temperature, process time, and installation conditions.

How to Choose a Large Vacuum Oven

For large-sample drying, electronic-material processing, powder drying, adhesive degassing, battery-material preparation, low-pressure drying of chemical materials, or small-scale process testing, first confirm sample dimensions, batch quantity, target temperature, vacuum level, drying time, site power, and installation space. The DOV70 suits entry-level large-capacity needs; the DOV80 offers more chamber space or throughput; and the DOV100 is suited to applications requiring a deeper chamber or more room for large samples. Confirm the model against the sample and process requirements.

Applications and Product Features

Applications: Electronic and chemical materials, battery materials, powders, adhesives, composites, research organizations, school laboratories, factory processes, quality control, and materials testing.

Features: The large vacuum oven is designed for material drying, heating, degassing, and sample preparation under vacuum or low pressure. The heat-resistant safety glass allows observation; the vacuum gauge, door gasket, and temperature controller can be configured to suit requirements. Confirm vacuum and temperature conditions, loading method, and safety requirements for the sample.

Frequently Asked Questions

Q1: How do I choose between the DOV70, DOV80, and DOV100?

Start by comparing internal and external dimensions, sample size, batch quantity, shelf quantity, and installation space. The internal dimensions are W70 x D70 x H70 cm for the DOV70, W80 x D80 x H80 cm for the DOV80, and W80 x D100 x H80 cm for the DOV100. Confirm the final selection based on sample size, loading method, vacuum requirements, and process.

Q2: What applications suit a large vacuum oven?

It can support large-sample drying, electronic-material and powder drying, adhesive degassing, chemical-material processing, battery-material preparation, low-pressure material heating, and quality-control testing. Suitability depends on sample material, target temperature, vacuum conditions, process time, and intended use.

Q3: How does a large vacuum oven differ from a standard vacuum oven?

Standard vacuum ovens are commonly used for benchtop or small-to-medium samples. Large vacuum ovens are better suited to larger workpieces, higher sample volumes, or batch processing. Consider a large model when samples are larger, throughput is higher, or the oven must fit into a process workflow.

Q4: How should I choose the vacuum gauge and temperature controller?

Specifications list an imported Japanese analog vacuum gauge (0–760 mmHg) or an imported digital gauge. The temperature controller can be a P.I.D. microcomputer model with dual display and S.C.R. phase control, or a multi-step controller. Confirm the configuration based on operating preferences, recording needs, and process requirements.

Q5: What information should I provide for a quotation?

Provide the sample material, dimensions and weight, batch quantity, usual and maximum temperatures, vacuum requirements, process time, whether a digital gauge is needed, power supply, installation space, and moving route to help determine a suitable capacity and model.

Specifications are compiled from the available product information. Confirm the actual temperature range, vacuum-gauge and controller configuration, power supply, accessories, options, and supplied version for the selected model and application.
