CTD Winch systems
Hydrographic equipment, such as instruments for measuring conductivity, temperature and pressure of seawater at varying depths, otherwise known as CDT devices, require careful handling. Operators can rely on Rapp CDT winches from MacGregor for the reliable, accurate deployment and retrieval of precision instrumentation.
Features of Rapp CTD and hydrographic winches include:
- A broad depth range, with the ability to deploy between 3,000 and 7,000m of 8,18mm fibre-optic cable
- Active heave compensation
- Right-angled fairlead ensures the required fleet angle for the drum
- Electric variable frequency drive offers smooth, stepless operations
