Unwind Brakes

Kopper Kool Clutches and Brakes

Wichita Kopper Kool clutches and brakes are water cooled to allow for high thermal capacities. The units contain copper discs for excellent heat dissipation. Rubber air tubes allow for smooth, accurate control and consistent web tensioning.

Torque range – 2,720 to 1,600,000 lb-in (307 to 180,771 Nm)
Typical applications – Drilling rigs, Deck Equipment, Coilers, Slitters and Lumber Processing Equipment

ModEvo Tension Brake

Wichita ModEvo tension brakes are modular and provide smooth control at high line speeds. Their design optimizes the use of cooling air at slow speeds to achieve high heat dissipation in either rotational direction. A cooling fan can be added for additional heat capacity.

Torque range – 12 to 38,000 lb-in (1 to 4,293 Nm)
Typical applications – Light and medium duty Tensioning Applications

Water-Cooled Clutches and Brakes

Eaton Airflex water-cooled brakes are disc type, externally cooled units. These brakes can dissipate a large amount of heat and are available in a variety of models and sizes. Both spring-applied and air-applied options are available to suit your application.

Torque range: 2,700 to 2,830,000 lb-in (305 to 319,507 Nm)
Typical applications: Paper mills, drawworks, winches, mooring systems, dynamometers
