Single Layer Double Chamber Automatic BIPV Laminator OTCY-2754DD

The Ooitech OTCY-2754DD Single Layer Double Chamber Automatic BIPV Laminator is a high-performance lamination system engineered for large-format BIPV (Building Integrated Photovoltaic) and standard solar module production. Featuring a generous dual lamination area of 2700x5400mm per chamber, this automatic laminator is purpose-built for manufacturers seeking efficient, high-throughput lamination of oversized glass-glass modules up to 5000x2400mm. The system employs an advanced upper and lower double electrical heating design, delivering exceptional static temperature uniformity of ±2°C on the lower heating plate and ±1°C temperature precision across the entire working surface. With a fully automatic roller platform for loading and unloading, PLC plus touch screen operation, and an intelligent multi-recipe process control system, the OTCY-2754DD streamlines BIPV and solar module lamination while ensuring consistent, repeatable quality for monocrystalline, polycrystalline, and double glass module formats.

Technical Parameters

Technical Advantages

System Architecture and Composition

The OTCY-2754DD comprises a feeding section, Process 1 section, Process 2 section, unloading section, one Roots pump, one vacuum pump, and two distribution cabinets, forming an integrated and efficient lamination line.

Loading and Unloading Section

• Horizontal roller transmission controlled by a frequency conversion system ensures adjustable transmission speed that stays synchronized with the feeding and host machine speed
• Liftable universal wheels with manual control for flexible module positioning
• Photoelectric sensors installed at front and rear ends detect module positions and prevent modules from falling during unloading
• Integrated cooling fans beneath the unloading section with touch screen selectable cooling function for laminated modules

Advanced Dual Heating System

• Upper and lower electrical heating with a heating rate of no less than 1.5°C/min for rapid and uniform temperature ramp-up
• Lower heating plate constructed from 40mm thick Q235 steel plate with surface irregularity of ≤200um per square meter, ensuring superior flatness
• 28 independent single-point temperature control zones on the lower chamber heating plate, achieving static temperature uniformity of ±2°C across the entire lamination surface
• 6 regional temperature control points on the upper chamber for auxiliary heating with static temperature uniformity of ±5°C
• Standard temperature module with solid state relay precise control delivers outstanding temperature uniformity throughout the lamination cycle
• All temperature measurement points can be individually calibrated and are displayed in real time on the touch screen

High-Performance Vacuum System

• Process 1 section utilizes a ZJP600 Roots pump combined with a 2X-70 rotary vane vacuum pump, providing a vacuuming rate of no less than 630 cubic meters per hour
• Process 2 section uses a 2X-70 rotary vane vacuum pump with a vacuuming rate of no less than 70L/S, reaching 120Pa in under 100 seconds
• Ultimate vacuum of the working chamber reaches 40Pa; automatic mode maintains laminating chamber vacuum at no more than 100Pa
• Each chamber features Japanese SMC zero differential pressure pneumatic membrane two-way solenoid valves (VXZ260KG) for vacuum inflation with a freely adjustable inflation rate of 0-70L/S
• SMC pressure sensors in each chamber provide real-time monitoring with Pa-class vacuum gauge displayed on the touch screen
• Full manual override system allows manual inflation and chamber opening during unexpected power failures, minimizing production losses

Precision Transmission System

• Gear motor combined with variable frequency speed control and encoder control system drives the high-temperature cloth transmission via chain for precise positioning with repeat positioning accuracy within ±10mm
• Multiple high-temperature cloths connected in a continuous circular motion (large cycle) ensure uninterrupted transmission throughout the lamination process
• Chain tensioning design compensates for chain wear over prolonged use, maintaining smooth and reliable transmission

Pneumatic Lifting System

• Pneumatic lifting controlled by three-position five-way solenoid valves with all key components including cylinders, lifting solenoid valves, and pneumatic solenoid valves sourced from Japanese SMC
• Exhaust throttle valves on each cylinder inlet and outlet port allow adjustable lifting speed for stable and synchronous operation
• Independent air control safety system prevents upper chamber from falling due to air pipe bursting or power failure
• Working cover height of 100-120mm with ultimate service opening height of 250mm or more

Intelligent Control System

• Fully automatic and manual dual control mode for loading, laminating, and unloading operations
• Integrates vacuum technology, pneumatic transmission, PID self-tuning heating, programmable control, and relay control technology for complex lamination and curing processes
• Real-time display and recording of all critical system parameters including upper and lower vacuum degree, table temperature, and alarm information
• PLC with network interface enables computer communication and meets modern industrial automation control requirements
• Independent control buttons on loading and unloading platforms with segmented advance control on the loading platform for convenient operation
• High-quality touch screen with intuitive interface, high sensitivity, sound and light process prompts, and easy parameter setting
• Multiple process parameters displayed simultaneously for efficient monitoring with multiple stored process recipes for quick production changeover
• Automatic process parameter memory that retains settings after restart with automatic logging of main operating steps for module quality analysis
• Lamination count statistics for shift tracking, component output monitoring, and reference data for maintenance and consumable replacement scheduling

Built-in Cleaning System

• Efficient upper and lower circulation cleaning system integrated into the laminator ensures the silicone membrane and heating surfaces remain free of residue for consistent lamination quality

Product Applications

BIPV Module Manufacturing

The OTCY-2754DD is specifically designed for Building Integrated Photovoltaic module production, accommodating oversized glass-glass formats up to 5000x2400mm with glass thicknesses ranging from 6 to 26mm. The large dual lamination area of 2700x5400mm per chamber and the ability to handle modules weighing up to 600Kg make it an ideal solution for BIPV facade, roof, and curtain wall module lamination.

Standard Solar Module Production

Fully compatible with monocrystalline and polycrystalline solar modules, the laminator supports a wide range of cell technologies including PERC, TOPCon, IBC, ABC, HPBC, and MBB formats. The precise 28-point lower temperature control and advanced vacuum system ensure bubble-free, high-adhesion lamination across all mainstream module configurations.

Double Glass and Specialty Module Lamination

The robust double heating design and 35mm net chamber height accommodate double glass modules and specialty configurations. The adjustable vacuum and inflation rates combined with multiple stored process recipes allow rapid changeover between different module types and encapsulant materials without compromising lamination quality.

High-Volume Production Lines

With a working cycle of just 8 to 25 minutes and average working power of only 75KW against a rated 280KW capacity, the OTCY-2754DD delivers energy-efficient high-throughput lamination. The dual-chamber configuration allows continuous production flow, and the fully automatic roller platform loading and unloading system integrates seamlessly into MBB full automatic solar panel production lines.
