• Automotive components and aerospace parts
• Plastic, metal, chemical and building materials
• Medical devices and military applications

Key features

• Explosion-proof design available (model-dependent)
• Compact chamber layout with small footprint
• Energy-efficient refrigeration using zero ODP refrigerants
• LED true-color ultrathin touch screen controller with English menu
• Transparent electrothermal double-layer glass observation window (standard)
• Standard accessories: lead holes, lighting lamp, casters, stainless steel trays, cable
