T3 achieve long term turbine preservation through dehumidification

Achieve long-term turbine preservation through dehumidification

Humidity levels on offshore wind farms can often reach up to 100%. When temperatures drop overnight, condensation can damage circuits, corrode the nacelle of your wind turbines and affect their performance. This can massively impact your operation and maintenance costs, reduce turbine lifetimes and require extensive downtime.

The right dehumidification systems stop condensation at the source, so it never threatens the performance and longevity of your machinery. Preserve your power generation and cut down running costs with our proven dehumidifiers – built to last and deliver optimal returns on investment.

Humidity control and drying for offshore wind turbines: FAQs

What are the consequences of not using dehumidifiers on offshore wind farms?

Failure to use dehumidifiers around your offshore wind turbines can have severe consequences for your equipment, personnel and facilities:

  • Bearings, gears and towers corrode and rust due to saltwater on surfaces

  • Switching mechanisms short-circuit, among other electrical failures

  • Mould and mildew growth damages materials and risks the health of maintenance personnel

  • Maintenance, repair and part-replacement costs skyrocket

  • The lifespan and performance of mechanical and electrical systems falls

  • Puddles and slip hazards can endanger the safety of your personnel

The right drying technology prevents these problems, leading to performance improvements, greater safety and reduced running costs.

How does dehumidification increase the lifespan of offshore wind turbines?

The moisture and saltwater produced on offshore wind farms can infiltrate equipment over time, causing damage to components that reduce their long-term performance. Corrosion and rust can also damage materials, meaning they break down sooner.

Industrial dehumidifiers greatly reduce the impact of moisture on your offshore wind turbines, extending lifespans, preventing corrosion, avoiding electrical faults and minimising other moisture-related damage to ensure many more years of operation for your turbines.

Can dehumidification improve the efficiency of offshore wind turbines?

Yes – by maintaining optimal humidity levels, dehumidification helps ensure that mechanical and electrical systems operate efficiently, leading to better wind energy generation and overall turbine performance.

Can dehumidification systems reduce maintenance costs for wind turbines?

Yes. One of the primary causes of electrical faults, mechanical failures and corrosion on wind farms is uncontrolled humidity. As dehumidifiers greatly reduce the amount of moisture in the air, this prevents this common issue from affecting your wind turbines as frequently.

Installing dehumidifiers can save you significantly on maintenance costs and repairs in the long term, and limit downtime on your sites.

Are your dehumidification solutions cost-effective on offshore wind farms?

We engineer our dehumidifiers and professional fans to be as energy-efficient as possible, making our solutions some of the most cost-effective available.

Alongside the potential reduction in maintenance costs and increase in turbine lifetimes, investing in dehumidification systems can save you money and deliver a substantial return on investment.

What types of dehumidification systems are used on offshore wind farms?

We recommend using desiccant dehumidifiers on offshore wind farms. These units are specially engineered to perform at low temperatures and high humidity levels, making them perfectly suited for these environments.

However, if your wind farms are on land, condensation dehumidifiers can provide the same level of moisture control with greater efficiency.

Talk to our specialists in energy and renewables climate control for impartial advice on devising a bespoke dehumidification system for your facilities.

How do you ensure your dehumidification solutions will protect my wind turbines?

Our highly trained professionals take great care in planning the most suitable dehumidification solution for your wind farms. First, we will inspect your site to calculate the climate parameters for your installation, before then recommending the right solution for these specifications.

Before installing stationary dehumidifiers, we will test the concept using our portable dehumidifiers. Once this has proven to be effective, only then will we put the permanent solution in place.

Reach our experts if you’d like to learn more about how we recommend the most fitting dehumidification system for your wind turbines.

Can I buy your humidity control technology for wind farms online?

We don’t make our dehumidifiers available to purchase online to ensure that every system we design, manufacture and supply fits your exact requirements. By taking a consultative approach with a highly-trained expert, we make sure that you are only recommended equipment that meets your needs – and fulfils these in the most efficient, cost-effective way possible.

Across all of our products, VAT-registered companies can get a quote very quickly by pressing 'I want to buy' and inserting your enquiry and contact details.

How soon can you supply your humidity control technology to my at-sea wind farm?

This varies on a case-by-case basis. For some standard products, accessories and consumables, we can provide day-to-day delivery. For larger orders or more bespoke humidity control solutions, there may be a longer lead time.

By reaching out to our experts we can put you in touch with your nearest local supplier so you can receive the products you require in the most timely manner possible.
