Spiral technology
A high-speed roll-up system engineered for long-lasting performance.
Thermicroll® Spiral Doors are designed to combine high performance with structural simplicity. The system delivers speed, insulation, security, and operational continuity, while maintaining a robust, streamlined mechanism engineered for intensive use.
Travel and roll-up movement along high-density polyethylene guides
At the core of Thermicroll® Spiral technology is a travel and roll-up system based on high-density polyethylene guides. The guides are machined from solid material in-house using CNC equipment to achieve precise geometry that is fully consistent with the door’s operating requirements.
This solution allows the panels to travel and roll up along a controlled path, enhancing speed, stability, and smooth, continuous movement.
The difference lies in the Spiral system
The high-density polyethylene Spiral guides ensure precise, quiet, and reliable movement, even under intensive operating conditions.
The spring-less design reduces mechanical complexity and simplifies maintenance over time.
Speed, insulation, operational continuity
Thermicroll® Spiral Doors are designed to reduce waiting times during the movement of goods and people. Speed, thermal insulation, and suitability for intensive use help optimise production processes and minimise resource losses in industrial environments.
High-speed opening
Opening speeds of up to 1.5 m/s on compatible models, with inverter-controlled drive.
Intensive use
Thermicroll® Spiral Doors are designed for intensive use, with a service life of up to 3 million operating cycles when properly maintained at regular intervals.
Thermal insulation
Insulated solutions help separate areas with different climate-control requirements, contributing to reduced thermal losses.
Discover the Thermicroll® Spiral range
The Thermicroll® Spiral system is available in multiple configurations designed to meet different requirements for insulation, speed, security, ventilation, acoustic reduction, and temperature-controlled applications.
Every detail serves a purpose
High-density polyethylene guides
They allow the door to travel and roll up along a dedicated path.
In-house manufactured panels
Developed to provide lightweight performance and durability within the Spiral system.
Push & pull drive system
Available across the range, it contributes to the system’s controlled movement.
Counterweight balancing system
A feature worth highlighting, as it clearly demonstrates the system’s mechanical simplicity, as discussed during the meeting.
Inverter-controlled drive
Available on the main Spiral models, it supports high-speed operation and precise motion control.
ENERGY SAVING AND EFFICIENCY
Reduced energy loss, greater efficiency across industrial workflows
In a production environment, every opening cycle affects transit times, internal temperatures, and overall process efficiency. By combining thermal insulation, high-speed operation, and suitability for intensive use, Thermicroll® Spiral Doors help reduce waiting times and optimise the movement of goods and people.
Spiral technology therefore contributes to a tangible objective: maintaining high operational performance while reducing waste caused by downtime, energy losses, and frequent transitions between different environments.
