COTES OVERPRESSURE SYSTEMS – THE CWO
Keeping wind turbines dry and salt-free
The patented Cotes Overpressure System tackles the many problems caused by airborne, salt-laden moisture inside offshore wind turbines, keeping the humidity and salt content of the air under control.
This breakthrough dehumidification setup creates a dry, salt-free environment inside turbine nacelles and towers. This reduces downtime, rolls back service costs and prolongs their service life – ensuring a better return on investment for any offshore wind turbine installation.
and cool as well…
Combining the Cotes Overpressure System with an add-on heat exchanger unit provides a straightforward, reliable way to keep the air around sensitive electronics under controlled conditions
The air from the overpressure system is cooled with cold air taken from the upper part of the tower and cooled still further by passing over the tower wall.
A 1000m3/hour overpressure unit can provide up to 40KWh of cooling effect, with a flow of dry air that’s free of salt.
