VIS - FLAMEPROOF BRAKES

About Vis

VIS is a product of COEL Italy.
Since 1976 COEL designes and manufactures brake motors and electromagnetic brakes producing all the components including the brake units in its facilities.
Thanks to this large experience, we invented on 2005 VIS, the modular brake system for hazardous location.
Our idea was based on the market demand of an easy solution in order to obtain a brake motor without modification of the motors or extension of the certificates.
With more than 30 years of experience in manufacturing brakes, we defined a new oversized standard, able to guarantee a range of modular brakes designed for heavy duty.
More than 35 controls made in the production process make of each VIS brake a top quality braking unit.
The VIS brakes range is in continuous development in order to make its quality and performance better and better.
Our range includes today various versions with braking torques between 3 to 16.000 Nm, suitable for any application.
For hoisting, travelling, positioning in hazardous location, the VIS brakes are the safe and reliable solution.

What's Vis

The VIS brake is an innovative modular flameproof spring applied disc brake unit.
The new concept is to apply an independent brake unit to a standard flanged explosion proof motor or to a transmission unit. The flanges input and output follow both IEC or NEMA standards.
Beside the face to face lines (IEC and NEMA), it is also available the COMPACT LINE version, suitable to be applied  to the NDE of an electric motor or to any transmission unit.
The VIS brakes are certified as independent components. It means that there are not coupling procedures in order to define the certification.

Why Vis?

The VIS brake is available in IEC flange face to face version (B5 63 to 315 ), NEMA standards (56 to 405) and COMPACT LINE for the mounting in the rear part of an electric motor or to a transmission unit.
The assembling is very fast.
Choosing the VIS brake, it’s very easy to make an explosion proof brake motor, reducing costs and delivery time.
The performance of VIS brakes is particularly high and the strong structure makes them suitable for very heavy duty and for every kind of application (hoisting, travelling, positioning...).
VIS brakes don’t need periodical maintenance such as adjustment of gap on work site.
The braking torque values are included between 3 to 16.000 Nm* and the electromagnets fitted inside the VIS brakes can be AC three phase or DC with built in rectifier*.
The cost of a standard explosion proof motor plus the VIS brake is considerably lower than an explosion proof brake motor and the lead time and reliability are much better.
