Double Chamber Furnace

Dual-Zone Tempering Technology for High Throughput, Process Stability & Operational Flexibility

The Double Chamber Furnace is a strategic evolution in glass tempering technology. Designed for factories that demand higher output, process separation, and superior production control, this furnace architecture divides the tempering process into two independent yet synchronized thermal chambers.

At Wings Logic, double chamber furnaces are the result of advanced thermal modeling, production flow analysis, and long-term R&D into heat stability and throughput optimization. These systems are engineered for processors who treat tempering not as a single machine, but as a production ecosystem.

Why Double Chamber Technology Exists

In conventional single-chamber furnaces, heating, soaking, and stabilization occur in one continuous zone. As production volumes grow, this creates limitations:

Double chamber furnaces solve these problems by separating thermal functions, allowing each chamber to be optimized independently. This is not redundancy — it is process intelligence.

Core Engineering Philosophy at Wings Logic

Wings Logic double chamber furnaces are designed around five engineering principles:

Thermal Decoupling for Process Precision
Independent Control of Heating & Soaking Phases
Maximum Throughput Without Thermal Compromise
Flexibility for Mixed Production Loads
Long-Term Stability Under Continuous Operation

Every chamber is treated as a controlled thermal environment, not just a heated tunnel.

Double Chamber Architecture Explained

Chamber 1 – Primary Heating Zone

The first chamber is responsible for:

Rapid and uniform glass heating
Initial temperature ramp-up
Overcoming coating reflectivity (Low-E glass)

This chamber is optimized for heat input efficiency, using either:

Advanced convection heating
Hybrid convection-radiation systems

Its role is to bring the glass close to its softening point quickly and uniformly.

Chamber 2 – Soaking & Thermal Stabilization Zone

The second chamber focuses on:

Temperature equalization
Stress homogenization through glass thickness
Edge-to-center thermal balance

This chamber ensures the glass reaches a thermally stable state before quenching, which is critical for:

Optical quality
Stress uniformity
Reduced breakage

This separation is the key to high-quality, high-speed tempering.

Furnace Chamber & Structural Engineering

Heavy-Duty Dual Chamber Frame

The furnace body uses:

Reinforced structural steel
Thermal expansion compensation design
Independent chamber insulation zones

This ensures:

Mechanical rigidity
Long-term alignment stability
Minimal heat loss between chambers

Structural integrity is essential when operating two thermal environments simultaneously.

Advanced Insulation & Thermal Isolation

Each chamber is insulated independently using multi-layer high-temperature insulation, preventing thermal interference. Benefits include:

Stable temperature control
Reduced energy waste
Improved heating accuracy

Thermal isolation allows each chamber to operate at its ideal thermal profile.

Convection & Heating System Design

Independent Heating Zones

Both chambers are divided into multiple independently controlled zones, enabling:

Local temperature correction
Edge compensation
Thickness-specific tuning

Zone independence allows operators to process mixed glass sizes and thicknesses without sacrificing quality.

Advanced Airflow & Heat Transfer

In convection-based designs, Wings Logic uses:

High-efficiency blowers
Optimized air duct geometry
Precision nozzle arrays

Airflow is modeled to ensure:

Uniform heat penetration
Minimal turbulence imbalance
Consistent surface heating

This level of airflow engineering is the result of continuous R&D and field validation.

Glass Transport & Synchronization

Precision Ceramic Roller System

Glass moves through both chambers on high-precision ceramic rollers, engineered for:

Dimensional stability
Smooth rotation at high temperature
Minimal surface marking

Roller alignment and speed synchronization are critical to avoid:

Roller wave
Optical distortion
Edge stress variation

Chamber-to-Chamber Transfer Control

The transition between chambers is digitally synchronized to ensure:

No temperature shock
No speed mismatch
No glass instability

This seamless transfer is what enables continuous high-speed production.

Quenching System – Converting Thermal Control into Strength

High-Performance Quench Engineering

After exiting the second chamber, glass enters the quench section, where:

Surface compression is induced
Internal tensile stress is controlled

Wings Logic quench systems feature:

Independent top & bottom air pressure control
Uniform nozzle distribution
Adjustable quench intensity

This ensures:

Consistent fragmentation pattern
High mechanical strength
Excellent optical quality

Optical Quality & Stress Profile Control

Double chamber furnaces excel in producing optically superior tempered glass because:

Glass reaches thermal equilibrium before quenching
Stress gradients are minimized
Surface distortion is reduced

Wings Logic systems minimize:

Anisotropy
Roller wave
Edge deformation

This makes them ideal for architectural and façade glass.

Intelligent Control Software & R&D Logic

Recipe-Based Dual Chamber Control

The control system allows:

Independent recipes for each chamber
Thickness-specific heating curves
Automatic synchronization with quench settings

This provides:

Repeatable production
Fast changeover
Reduced operator dependency

Real-Time Monitoring & Adaptive Correction

Sensors continuously monitor:

Zone temperatures
Glass speed
Chamber stability

The system dynamically adjusts parameters, maintaining process stability under high load.

Energy Efficiency & Operational Economics

Despite higher output, Wings Logic double chamber furnaces are optimized for:

Efficient energy usage
Reduced heat loss
Stable power consumption

Energy efficiency is achieved through:

Advanced insulation
Optimized heating cycles
Intelligent power management

This delivers lower cost per square meter of tempered glass.
