Renewable Energy Sealing Solutions

High-Performance Seals for Sustainable Energy Applications

At Ashton Seals, we supply high-performance sealing solutions for the renewable energy sector, engineered to deliver reliability, durability and long service life in harsh outdoor environments. From wind turbines and solar installations to hydroelectric and energy storage systems, our seals ensure efficient operation, environmental protection and reduced maintenance in critical renewable infrastructure. 

In December 2015, Ashton's invested in a solar panel system, showcasing our commitment to renewable energy and the environment.

Sealing Solutions for Renewable Energy Systems

We provide sealing solutions for a wide range of renewable energy applications including:
Wind turbines (onshore and offshore)
Solar (photovoltaic) panel systems
Hydroelectric and tidal energy systems
Battery storage and power conversion systems
Substations and electrical infrastructure
These applications require robust sealing solutions capable of withstanding continuous exposure to weather, temperature changes and mechanical stress.

Performance in Extreme Environmental Conditions

Renewable energy systems operate in challenging outdoor environments, often over long service lifespans:
Exposure to UV radiation, ozone, and weathering
Contact with moisture, seawater and humidity
Wide temperature variations (including extreme cold and heat)
Continuous mechanical movement and vibration
For example, seals in wind turbines must perform reliably across components such as gearboxes, bearings, pitch systems and nacelles, each with unique operating conditions .
Effective sealing solutions help:
Prevent ingress of water, dust and contaminants
Maintain lubrication in gearboxes and bearings
Improve system efficiency and performance
Reduce maintenance and operational downtime

Renewable Energy Standards & Certifications

Sealing solutions in renewable energy must meet strict performance and environmental standards:
Key Certifications & Standards
IEC 61400 - Design and performance standards for wind turbines
ISO 9001:2015 - Quality management systems
TS EN ISO 4892-2 - UV and weather resistance testing for outdoor materials

Additional Requirements

Resistance to UV, ozone and environmental degradation
Long-term durability (20+ year operational lifespans)
Compatibility with electrical and mechanical systems
Certification for use in offshore and harsh environments
These standards ensure sealing components are fit for purpose, reliable and capable of long-term performance in renewable energy systems.

Products for Renewable Energy Applications

We supply a comprehensive range of sealing products suitable for renewable energy systems including:
O-rings and elastomer seals
Rotary shaft seals and bearing seals
Hydraulic seals for pitch and control systems
Gaskets and environmental sealing solutions
Cable and enclosure sealing systems
These products are widely used across wind turbines, solar panel systems, substations and energy infrastructure.

Materials & Performance

Renewable energy sealing solutions must be designed for durability and efficiency.

We offer materials that provide:
Resistance to UV, ozone and weathering
Compatibility with lubricants, oils and environmental exposure
Durability under mechanical stress and vibration
Long service life in outdoor and offshore environments
Common materials include:
EPDM – excellent weather and UV resistance
FKM (Viton®) - chemical and temperature resistance
HNBR - high mechanical strength
PTFE - low friction and long-term performance

Typical Applications

Our sealing solutions are used across a wide range of renewable energy systems:
Wind turbine gearboxes, bearings and pitch systems
Solar panel frames, enclosures and electrical housings
Hydroelectric turbines and fluid systems
Battery storage systems and power electronics
Offshore renewable energy infrastructure
These applications require reliable sealing to ensure efficiency, sustainability and long-term operational performance.
