Lisec VSA 25 D1 super space applicator

Lisec superspace VSA 25

The LiSEC VSA (Vertical Spacer Applicator) 25 D1 is a fully automatic, high-precision machine designed for applying flexible, warm-edge spacers (such as Super Spacer) to glass sheets during the production of insulating glass (IG) units. The "25" indicates a maximum glass handling height (2,500 mm), while the "D1" signifies a, often, specialized applicator head designed for high efficiency in applying spacer materials, particularly with, but not limited to, two-track systems for fast, varied-width production.
Key Features and Capabilities:
Fully Automatic Application: The machine automatically positions, feeds, applies, and cuts the flexible spacer material to size, ensuring a continuous, 90-degree perfect corner seal.
Two-Track Applicator Head: The D1 variant is specifically known for its, or can be equipped with, a two-track application head, allowing the machine to handle two different spacer widths simultaneously. This is ideal for manufacturing 2-fach (double) or 3-fach (triple) IG units with different air gaps without stopping for material changes.
Climate-Controlled Magazine: Spacers are stored in an air-conditioned, humidity-monitored, airtight container, ensuring the adhesive properties and material flexibility are maintained for perfect processing.
Precision and Speed: Patented, low-friction application techniques provide high-precision positioning with very short cycle times, making it ideal for high-speed, high-volume production lines (e.g., Velocity Plus).
Integrated Butylation: The applicator head includes a built-in system for applying a butyl cord to the spacer, ensuring airtight, high-quality insulating glass units.

Optimized Corner Quality: A special, automated corner punching device ensures the spacer is applied with precise, 90-degree corners, improving the structural integrity and seal.
Reduced Waste: The machine includes a system for controlled disposal of corner punch waste, keeping the work environment clean.
Technical Specifications (Typical of the 25/20 Series):
Maximum Glass Size: 2,500 mm x 2,000 mm (can vary by specific configuration).
Minimum Glass Size: 350 mm x 180 mm.
Total IG Thickness: 12 to 60 mm.
Glass Thickness: 3 to 15 mm.
Spacer Widths: Capable of handling materials from 8 to 25 mm.
The LiSEC VSA 25 D1 is a critical component in advanced insulating glass lines that prioritize speed, accuracy, and the ability to handle flexible, warm-edge, and complex, multi-component insulating glass units.
