Water Cooled Brakes

Water Cooled Brakes (WCB) are designed for constant slip and severe high heat braking applications. The brakes are air actuated and cooled with a continuous flow of coolant from either a closed or open loop cooling system. WCB brakes are specifically designed for applications in which large thermal loads must be dissipated.

Available with two actuation methods, either airtube or piston. The airtube is corrosion resistant and no special coatings or treatments are required. Field service is simple and error free.

Retrofit kits are available to convert an existing single or dual piston actuated WCB to airtube actuation with no other modifications required.

Typical applications include:

  • Dynamometers
  • Forestry / logging equipment
  • Anchor handling and towing winches
  • Mooring winch systems
  • Petroleum drilling equipment and tension brakes

Water Cooled Brakes

Spring Set

Similar to the WCB, the WCB/SS is a spring applied, air-release, fail-safe brake.

Typical applications include:

  • Forestry and logging equipment
  • Anchor handling and towing winches
  • Mooring winch systems
  • Petroleum drilling equipment

Water Cooled Brakes

Dual Actuated

The WCB/DA combines air applied control and spring applied fail-safe features, is specifically designed for heavy duty braking and holding applications, where emergency stop and parking brake features are necessary.

Typical applications include:

  • Forestry and logging equipment
  • Anchor handling and towing winches
  • Mooring winch systems
  • Petroleum drawworks equipment

Airtube Advantage:


Standard with all WCB units, the reinforced neoprene airtube reacts accurately to small pressure changes and offers no resistance to movement - therefore increasing sensitivity.

Airtube

Our airtubes are inherently corrosion resistant and require no additional coatings or protective treatments. They are ideal for marine and other harsh environmental applications where real world conditions can severely affect performance and reliability.

Finally, the WPT® airtube design ensures product performance without the need of expensive and complicated control packages. Controllability is as easy as a simple pressure control valve and regulator.
