Enhancing Efficiency in Solar Energy Systems
In the realm of renewable energy, solar energy power systems require robust and precise components to maximize energy efficiency.
Penlink provides rotary unions specifically designed for parabolic trough concentrated solar power (CSP) fields, enabling smooth rotational movement of collector piping. These rotary unions feature:
- High-temperature packing sealing systems.
- Internal corrosion-resistant bearings.
- Customer-specified designs for direct welding to piping systems.
In addition to CSP solutions, Penlink offers turnkey products for solar panel movement systems, enabling 360-degree rotation to optimize positioning. Our offerings include:
- Electrical slip rings for seamless signal and power transfer.
- High-accuracy encoders for precise tracking.
- Motors and drives for smooth and reliable operation.
We also support solar cell inspection with our SWIR cameras, which can be mounted on tripods or drones for detailed evaluations.

Reliable, High-Performance Components for Solar Energy Applications
Penlink’s rotary unions, slip rings, and encoders are designed to meet the demands of modern solar power systems.
Whether supporting CSP fields or enabling solar panel movement, our components are engineered for durability, precision, and reliability in renewable energy applications.
