LBT-GW100B Fully Automatic Control Explosion-Proof High-Temperature Vacuum Drying Oven

Name: LBT-GW100B Fully Automatic Control Explosion-Proof High-Temperature Vacuum Drying Oven
Brand: Laibote (Tianjin) Testing Machinery
Availability: InStock

An explosion-proof high-temperature vacuum drying oven is a cabinet-type drying device that dries materials under negative pressure. It employs a vacuum pump to remove air and moisture, creating a vacuum within the chamber, which lowers the boiling point of water and accelerates the drying process. It is used for powder drying, material annealing, semiconductor processing, new‑energy battery testing, encapsulation testing of aerospace components, as well as degassing and dehydration during electronic product manufacturing, and for hardening and drying applications. It is widely employed in research fields such as electronics and chemistry, agricultural science, and environmental protection.

LBT-GW100B Fully Automatic Control Explosion-Proof High-Temperature Vacuum Drying Oven

Description

Product Introduction:

The explosion-proof GW series high-temperature vacuum drying oven builds on high-temperature drying by incorporating a vacuum environment, significantly lowering the boiling point and vapor pressure. This provides a dust-free, vortex-free drying process and a gentle operating environment, while also facilitating the easy collection, venting, or reuse of solvent vapors. Furthermore, storage, heating, testing, and drying are all conducted in an oxygen‑free or inert‑gas‑filled atmosphere, thereby minimizing oxidation of the test samples.

Product Features:

l Controller: Equipped with a color touchscreen controller, it displays temperature and pressure on a single screen, offers precise temperature control, supports programmed and set-point operation, allows arbitrary setting of the operating temperature, features data logging and storage, includes USB data export functionality, and provides fault alarm and diagnostic query capabilities.

l Explosion-proof electrical cabinet, explosion-proof conduit, explosion-proof panel-mounted controller, and explosion-proof temperature and pressure sensors, heating elements, solenoid valves, and vacuum pumps.

l The rectangular studio has an effective volume of.

l High-quality SUS304 stainless steel reinforced door, with large-angle retractable steel plate hinges.

l One‑step injection‑molded high‑temperature silicone rubber door seal for effective sealing.

l Low-temperature cooling and sealing ring assembly.

l Buckle-type elastic adjustment door lock, ensuring excellent vacuum integrity.

l Specialized high-temperature sealing valve components.

l The exterior of the equipment features a smooth finish, crafted using an electrostatic powder-coating process on cold-rolled steel, resulting in a sleek and aesthetically pleasing design.

Product Advantages:

l The vacuum environment significantly lowers the boiling point of liquids that need to be removed, enabling the equipment to be readily applied to heat-sensitive materials.

For samples that are difficult to dry, such as powders or granular materials, vacuum drying can effectively reduce drying time.

l For complex mechanical components or other porous samples, vacuum drying is employed after cleaning; this method leaves no residual substances. Compared with conventional drying that relies on air circulation, powdered samples are not blown or displaced by the flowing air.

l Under vacuum or inert conditions, the risk of thermal explosion caused by oxide formation is eliminated, ensuring safer and more reliable operation.

l The unique cooling structure ensures maximum vacuum integrity, preventing any leakage.

l The vacuum‑relief device can reduce the impact of strong airflow on the test specimen itself.
