Water-Free Corrosion-Resistant Vacuum Atmosphere Box Furnace

Product Overview

The GWDL-ZQLB Series corrosion-resistant vacuum atmosphere furnace is designed for high-performance thermal processes without requiring water-cooling. By increasing the thickness of the insulation layer and using high-efficiency thermal materials, the furnace maintains optimal exterior temperatures (≤40°C), even under maximum operating temperature conditions. This makes it ideal for sensitive laboratory environments and industrial settings where water circulation is unavailable or undesired.

GWDLTHERMO supports full customization to meet your specific process, space, and material requirements. We’re committed to delivering intelligent, safe, and user-friendly thermal solutions.

Key Features

• No Water Cooling Required
  Thanks to reinforced insulation and advanced material engineering, the furnace operates safely without external water cooling. Built-in air-cooled double-layer casing ensures excellent thermal management.
