Wind power accumulators, bladder replacement kits, and related equipment
Piston, bladder, and diaphragm accumulators
Piston accumulators
- Highly durable with extremely low nitrogen permeation rates.
- Low service temperature ratings comply with US and European pressure vessel codes.
- Made in USA and Europe, for best-in-class lead times.
Crimped piston accumulators
- Compact, lightweight and designed specifically to replace diaphragm type accumulators in systems.
- Lower pre-charge permeation offers in longer intervals between inspections.
- Available in 40 mm to 150 mm bore, and up to 10 liter capacities.
Bladder accumulators
- Greer and Olaer manufacturing expertise is part of Parker’s advantage as a major supplier of 10 to 57 liter bladder accumulators and bladder repair kits.
- Dual certified to both ASME and PED.
- Unique Rilsan coated shells drastically reduce friction between the shell and the bladder, prolonging service life.
Diaphragm accumulators
- For wind turbine braking systems and emergency energy reserve.
- Designed to be compact and lightweight.
- PED compliant.
Bladder replacement kits
Bladder replacement kits
- Special bladder compounds developed for wind industry.
- Offer long life, low nitrogen gas permeation and a wide operation temperature range.
- For repair of existing accumulators in the field.
Related equipment—Bladder charging kits, sensors, and air/oil coolers
Air/oil coolers
- Broad product range designed for rugged environments, offering efficient cooling capacity up to 300kW.
- Design, materials, and components combine to offer long life, high availability, low service and maintenance costs.
- Well suited for gearbox hydraulic system applications.
Universal accumulator charging kits
- Offer a wide variety of charging adaptors to fit varied gas valve designs and accumulator technologies, including bladder, piston, or diaphragm types.
- Manufactured globally.
- Kits equipped with two pressure gauges, enabling a more accurate gas pressure measurement for low-, medium-, and high-pressure requirements.
Coolant evaporation inhibitor
- For GE 1.5 MW wind turbine open-loop cooling systems.
- Ensures correct water/glycol coolant mixture and levels in the insulated-gate bipolar transducer (IGBT) circuit.
- Greatly inhibits water evaporation in the coolant solution and stops ingress of airborne contaminants, eliminating the need for continuous coolant monitoring during the warm season.
