AquaMakks Water Cooled Clutches & Brakes

AquaMaKKs water cooled clutches and brakes are designed to provide accurate torque control for heavy-duty tensioning applications.

AquaMaKKs™ clutches and brakes are pneumatically or hydraulically controlled and water cooled. They consist of a series of alternating friction discs and water jackets. Torque is transmitted by applying axial force from the pneumatic, hydraulic, or spring set actuator. Copper wear plates are used for excellent heat dissipation. Models are available in 19", 25", and 36" diameter sizes. Torque ranges from 66,500 in.lb. @ 80 PSI to 1,611,000 in.lbs. @ 100 PSI.

Features include:

• Durable air tube design with high strength reinforced neoprene air-tubes, offering longer service life
• Water channels for balanced water flow for the highest thermal capacity
• Long-lasting friction material with minimal wear on mating copper
• Copper alloy wear plates enable higher heat transfer than any other metals
• Hub spline provides perfect alignment of rotating discs
• External air & water connections
• Release springs ensure complete disengagement
• Adjustment for wear is easily accomplished by removing shims without any unit disassembly
• Unique torque pin column arrangement provides structural integrity of case
• Open case design with covers for safe, simple, visual inspection and easy maintenance

New engineered composite water jacket improves performance   Wichita engineers have utilized the latest cutting edge technologies and state-of-the-art materials to develop a revolutionary new breakthrough in water cooled clutch and brake design... composite water jackets (patent pending). Corrosion resistant, saltwater friendly Composite material will not corrode, so salt water and water sources with high PH acidic values can be used for cooling without the need to supply fresh water.

A new 36" composite water jacket weighs approx. 95 lbs. A comparable 36" cast iron jacket weighs approx. 375 lbs. The reduced weight is a significant maintenance benefit, as well as when equipment is installed in weight restricted applications such as mobile yarders in the forestry industry.

Other composite water jacket benefits include:

• Improved channeled water flow - achieved via groove designed and molded into jacket providing enhanced cooling capability
• Fast & easy maintenance created from the lightweight composite jacket design that is about 25% the weight of the competitors metal design
• Water jacket design and material allows for longer life, requiring fewer replacements
• Reduced overall clutch weight – critical for weight restricted applications (eg: truck mounted)

No optional salt water corrosion protection is required

Dual actuator models provide both a spring-set parking and a precision tension braking capability in one compact unit.

Option packages and custom engineered AquaMaKKs models are available to meet your specific requirements The versatile AquaMaKKs product platform can be modified to accommodate your application specifications. With AquaMaKKs, you get more than just a water cooled brake, you can get a turnkey solution. Whether you need a brake painted a preferred color, water connection kits, covers, shaft assemblies, or deck mount assemblies, Wichita will provide a custom engineered solution to meet your specific needs. Other variations include LISSB models for marine deck use, dual actuator units, and arctic packages for operating temperatures to -45°C. Call Wichita today for more information.

LI-SSB models are designed to withstand highly corrosive offshore deck environments where sea spray and direct seawater splash is prevalent.

wcbAM Water Cooled Brakes

Lightweight corrosion resistant water cooled brakes
designed for direct replacement of WCB style brakes

The wcbAM is a new, lightweight version of our popular AquaMaKKs® water-cooled brakes. All water jackets, including the float, center and back plate, are made of corrosion-resistant, lightweight engineered composite material.

Along with a full set of composite water jackets, the models feature a newly-designed, lightweight, corrosion resistant aluminum actuator head.

The 236 wcbAM model only weighs approximately 1,920 lbs. while other 236 size comparable iron models weigh approximately 3,550 lbs. The reduced weight of approximately 40% is a significant maintenance advantage, as well as when equipment is installed on weight-restricted applications.

Features include:

• wcbAM Water Cooled Brakes are available in 24" & 36" sizes
• Wichita composite water jacket assemblies weigh at least 60% less than competitors
• Water jacket assemblies are interchangeable with competitors' parts
• All water jackets are made of corrosion-resistant, lightweight engineered composite material
• Complete brakes weigh at least 40% less than that of competitors
• Pneumatic and hydraulic actuations available
