EUROPE SPIRAL DUCT MACHINE

The REFRIWEB machine, model DR2C1.v2, is the main equipment for manufacturing ROUND SPIRAL TUBE. Complying with ABNT and SMACNA standards, it forms the tube and joins it with a spiral lock seam, ensuring airtightness and greater mechanical strength than any conventionally rolled duct of the same thickness. This is due to its quadruple lock seam, which provides additional reinforcement around the entire circumference of the duct, producing lighter ducts and even reducing installation costs. Used in air distribution networks, it serves ventilation, fresh air supply, refrigeration, extraction and heating applications, as well as various building construction needs.



This machine offers high repeatability, easy handling and low maintenance, with a robust construction, high wear resistance and an excellent finish. It is essential for those seeking to automate, speed up and ensure standardized, accurate and uniform production quality. Sophisticated equipment offering high efficiency and economy. Material is fed continuously from steel coils, which may be galvanized, carbon or stainless steel. It has an option for manufacturing ribbed (beaded) circular duct, providing greater structural strength with the same sheet thickness. This method offers excellent value for money, reducing weight in the completed installation while maintaining mechanical strength.

This equipment uses six processes in spiral tube manufacturing that give the parts unique characteristics, as described below:



DECOILER

Automatic uncoiling with adjustment to accommodate different internal coil radii.



AUTOMATIC SYSTEM

Controlled by a PLC with a touch LCD screen. It can operate autonomously, feeding, forming, lubricating and cutting the material without human intervention. The equipment is easy to handle and has preset parameters that ensure modern, fast and accurate production.



FORMING DIES

The equipment comes with a set of forming bands with diameters of Ø125, Ø150, Ø200, Ø250, Ø300, Ø350, Ø400, Ø450, Ø500, Ø550, Ø600, Ø650, Ø700, Ø750, Ø800, Ø900, Ø1000, Ø1200, Ø1400, Ø1500.



FORMING ASSEMBLY

A set of rollers forms the folds for the tube lock seam and also includes a beading system between the spiral seams, ensuring greater mechanical strength and tube rigidity.



CUTTING SYSTEM

Equipped with a flying cutoff, it ensures continuous production even while the tubes are being sheared. High-strength steel cutting rollers ensure long component life. Cutting is free of noise, chips and sparks, with no subsequent finishing required on the parts produced.



TUBE EJECTION

Automatic system for ejecting finished tubes, ensuring fast and continuous production.
