Renova brakes – always a disc ahead

16 October 2018

Renova has addressed the problem of high brake operating temperatures that, when not efficiently dissipated, cause the loss of the web tension consistency resulting in excessive component wear and dust pollution as well as higher production and maintenance costs.

With the company’s patented Turborex multi-disc brake, a double fan cooling and ventilation system contribute to a massive reduction in operating temperatures ensuring the discs and pads do not overheat, thereby maintaining tension and consistency at any line speed and roll diameter.

By virtue of its multidisc system - three to four discs of 180mm - the pressure is distributed on eight surfaces (six if three discs only) and the reduction of the disc diameter to 180mm guarantees a drop of circa 30% of the sliding speed of the friction materials - this bringing a reduction of the heat to be dissipated. The air flow is well distributed between the discs and the cooling systems work perfectly well on all surfaces.

Overall, two important benefits derive; firstly, a significant decrease in dust pollution on the working area and, secondly, considerable reduction of maintenance requirements with the resulting increase in machine efficiency and running time.

UK agent, Jarshire says that Turborex is 100% interchangeable with all existing brakes and is expected to perform for 42,000 working hours under extreme conditions (300 mt/min, 24 hours).  The brakes achieve high torque, together with minimal wear and heat generation - results that were not previously possible.

Renova is an Italian manufacturer and supplier of web tension control systems and roll handling systems. It was founded in 2005 by Gianpiero Re, designer in the 1980s of the innovative CX mono-disk brake series that featured a new fan ventilation allowing the temperature to lower quicker than previously. Subsequently, this technology became the reference for thousands of applications in the converting industry.
