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
