Kopper Kool Clutches and Brakes

Clutch Engineering offers Wichita Kopper Kool clutches and brakes, for applications such as drilling rigs, deck equipment, coilers, and more. These products are water cooled to achieve high thermal capacities while working within your applications. A featured hub spline provides perfect alignment of rotating discs. The units contain copper discs for excellent heat dissipation, which is a critical factor when working under conditions that will generate large amounts of heat. Engagement is achieved by pneumatic expansion of the airtube, which is an effective and reliable engagement method. This air-operated clutch also provides an accurately controlled continuous slip action for constant 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

Clutch Engineering provides Wichita ModEvo tension brakes for use with light duty and medium duty tensioning applications. These high-quality products are modular, and they can operate at high line speeds while still giving smooth control. Their advanced design is optimized to achieve high heat dissipation at low speeds, with the use of cooling air. This method for heat dissipation is possible in either rotational direction. A cooling fan can also be integrated into your system for enhanced heat dissipation capabilities. Included discs are manufactured to be the same thickness and each uses the same brake modules and actuators. Each disc can be specified with a minimum of one module, up to the maximum number of modules that can be fit around the disc. Available in five sizes: 250 mm, 300 mm, 350 mm, 400 mm and 450 mm diameters 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

Offered by Clutch Engineering, these Eaton Airflex water-cooled brakes can be integrated into paper mills, drawworks, winches, mooring systems, and many other mechanical systems. These well-made products are disc type, and each unit is externally cooled. These water-cooled clutches and brakes can dissipate large amounts of heat, and they are available various models and sizes. Both spring-applied and air-applied versions of this product are available to suit your application. These are specially designed and constructed to use water to absorb and dissipate the thermal loads associated with the most severe clutch and brake uses that may occur. Torque range: 2,700 to 2,830,000 lb-in (305 to 319,507 Nm) Typical applications: Paper mills, drawworks, winches, mooring systems, dynamometers
