Overview
B18 Built-in Refrigerator Hinge
Product Overview
The Atasan B18 built-in refrigerator hinge has been developed for integrated refrigeration applications requiring high load capacity, controlled door movement, and compatibility with furniture door systems. Designed for built-in refrigerators and upright freezers, the B18 combines durability, functionality, and integration flexibility within a single hinge platform.
Its parabolic axis structure and optimized motion geometry support smooth and controlled door movement while maintaining compatibility with modern kitchen furniture systems.
Parabolic Axis Motion System
The B18 incorporates a specially engineered parabolic axis mechanism designed to support progressive and controlled door movement throughout the opening cycle.
This geometry helps reduce friction and mechanical stress during operation while improving compatibility with thicker decorative furniture panels.
Benefits
- -Smooth and progressive door movement
- -Controlled opening and closing characteristics
- -Reduced friction during operation
- -Improved compatibility with furniture systems
- -Stable motion under load
Assisted Closing & Gasket Support
The integrated spring mechanism provides assisted closing characteristics at lower opening angles.
This function helps support gasket engagement and contributes to maintaining door sealing performance while reducing the likelihood of incomplete door closure.
Features
- -Assisted automatic closing
- -Supports gasket compression
- -Controlled closing movement
- -Enhanced user convenience
Wide Opening & Safety Features
The hinge platform is designed to support convenient user access while maintaining stable operation.
Motion Characteristics
- -115° opening angle
- -90° stopper system
- -Controlled free movement after 45°
- -Stable and predictable door behavior
The stopper system helps limit excessive door travel in applications installed close to adjacent cabinetry or walls.
High Load Capacity & Structural Strength
The B18 has been developed for demanding refrigeration applications involving heavy appliance and furniture door combinations.
Its reinforced construction utilizes high-quality cold-rolled sheet metal, precision axis geometries, and durable structural components designed to support long-term operation under load.
Corrosion Resistance & Surface Protection
The hinge incorporates zinc-coated components developed for kitchen and refrigeration environments.
This surface treatment supports corrosion resistance and helps maintain long-term appearance and durability in humid operating conditions.
Furniture System Compatibility
The B18 is engineered for seamless integration with built-in refrigeration systems and furniture doors.
Compatibility Features
- -18–19 mm standard furniture panels
- -Compatible with 16 mm panels using spacers
- -41.5 mm and 45 mm mounting depths
- -Compatible with various door constructions
- -Ergonomic installation structure
Durability & Life Cycle Performance
The B18 platform undergoes internal validation and endurance testing programs designed to evaluate performance under representative operating conditions.
Depending on configuration, tested versions have achieved performance references ranging from 50,000 to 100,000 opening and closing cycles.
OEM Integration & Manufacturing
The hinge platform has been developed to support appliance manufacturers requiring flexibility, durability, and efficient production integration.
Its design supports compatibility with automated manufacturing processes and a wide variety of refrigeration platforms.
Applications
- -Built-in refrigerators
- -Upright freezers
- -Furniture-integrated cooling systems
