LBT-GH512 Vacuum Drying and Defoaming Curing Oven for Motors

Vacuum drying ovens, by combining high‑temperature drying with a vacuum environment, significantly lower the boiling point and vapor pressure, providing a dust‑free, vortex‑free drying process and a gentle operating environment. They also facilitate the easy collection, discharge, or reuse of solvent vapors. Furthermore, storage, heating, testing, and drying are conducted in oxygen‑free or inert‑gas‑purged conditions, thereby minimizing oxidation of the test samples. Manufactured using imported lasers and CNC machining equipment, these units are ideal for industrial applications, laboratories, and research institutions, serving purposes such as drying, baking, wax melting, sterilization, and defoaming.

LBT-GH512 Vacuum Drying and Defoaming Curing Oven for Motors

Description

Product Introduction:

Vacuum drying ovens, by combining high‑temperature drying with a vacuum environment, significantly lower the boiling point and vapor pressure, providing a dust‑free, vortex‑free drying process and a gentle operating environment. They also facilitate the easy collection, discharge, or reuse of solvent vapors. Furthermore, storage, heating, testing, and drying are conducted in an oxygen‑free or inert‑gas‑purged atmosphere, thereby minimizing oxidation of the test samples. Manufactured using imported lasers and CNC machining equipment, these units are designed for industrial facilities, laboratories, and research institutions to perform drying, baking, wax melting, sterilization, and defoaming.

Product Features:

1. A single‑use, high‑temperature‑resistant silicone rubber door seal, integrally molded in place, is installed between the chamber and the door to ensure effective sealing and maintain a high vacuum level inside the chamber.

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

3. The enclosure is constructed from high-quality cold-rolled steel sheet, with an electrostatic powder-coated finish that provides a hard, durable coating and excellent rust resistance.

4. The workbench is made of high-quality 304 stainless steel, featuring rounded corners, a smooth and streamlined design, and easy-to-clean surfaces.

5. The space between the cabinet body and the working chamber is filled with ultra-fine glass wool insulation, providing excellent thermal insulation and effectively ensuring stable, accurate internal temperatures while minimizing environmental influences.

6. The chamber door is equipped with a square, double-layer tempered glass observation window, allowing clear visibility of the heated items inside while providing excellent thermal insulation. This effectively prevents burns to operators.

7. The heater is mounted on the outer surface of the chamber to maximize internal temperature and facilitate interior cleaning.

8. Temperature control is implemented using microcomputer-based intelligent digital technology, featuring industrial‑grade PID auto‑tuning and a four‑digit dual‑LED display.
