Spiral 80 Special Application insulated doors: Features and advantages

Insulated industrial rolling shutters are a technological evolution in the field of doors, with the goal of dividing operational areas marked by different acoustic and thermal intensities or intended for different uses.

Thermicroll® Spiral Door ISO 80 industrial doors are part of the range of insulated shutters, which have been committed for years to providing products capable of supporting and managing every business logistics problem.

The characteristics of the refrigeration doors are suitable for any type of industry. Discover all speed door solutions by application area.

Spiral 80 Special Application insulated door is the top of our company’s products, designed to guarantee an unrivalled level in terms of speed, safety and isolation between environments.

The thickness of the panels and their shape are the essential elements for operating in very rigid climatic conditions. In fact, the model differs because of its specific resistance to harsh temperatures and therefore to refrigerated environments.

The patented circular spiral winding is made of high-density polyethylene and the covering is composed of double-walled aluminium or steel panels with high thermal and acoustic insulation and the possibility of inserting polycarbonate windows.

Thanks to extreme response speed, minimum displacement noise, absolute safety, superior winding with reduced space requirements, due to the special processing of the curved insulated profile, Spiral 80 Special Application insulated doors are a cutting-edge product in the speed-doors sector. In addition, ceiling anchors are not required, unlike traditional speed doors. The ground impression is completely absent when the damper is open. Last but not least, it is the very attractive aesthetics, able to provide the customer with an excellent business card of its activity.

These and other innovations make Thermicroll® the leading company for industrial shutters in design, research and development.

Spiral 80 Special Application: patented italian shutters

The simplicity of this industrial door (not only refrigeration door) allows to reduce costs, maintenance and assembly times, but at the same time enhances its quality and functionality.

The insulated damper, which uses mechanical and electrical components of the highest quality, is entirely developed, designed and built in Italy, in one of the company’s various facilities.

The first guarantee on insulated doors is given by repeated tests on all industrial doors during the various phases before and after installation.

Specifically, this model has been validated to withstand 1 million opening and closing cycles: the cold store doors are completely reliable thanks to the numerous thermal tests carried out in the various phases of production and installation.

All our insulated roller shutters comply with the 12453-12445/EC and UNI EN 13241-1/EC standards and are certified as exclusive and original products, unique in their strength, practicality, functionality and quality.
