Our HPU project process is meticulously planned and executed by a skilled team of engineers and technicians. Here's what you can expect when you choose Airline Hydraulics for your HPU needs:
First, we identify your specific system needs. While many customers approach us with only a general idea, our team excels at translating those initial concepts into detailed specifications.
Our approach is proactive and comprehensive. We begin by asking questions about the desired system parameters, such as pressure, flow rate, and operational environment. This collaborative process helps us shape the project, ensuring we design a solution tailored to your unique needs.
This focus on collaboration is beneficial for everyone involved, as a full understanding of the project requirements ultimately results in a more efficient and effective HPU.

What makes a quality hydraulic power unit stand out? Let's dive into how our component selection process ensures each unit meets industry standards.
Component selection is a critical step in building a hydraulic power unit. With the scope approved, we begin sourcing the necessary components. Quality control starts at this stage; our team meticulously checks each part to ensure it meets the specified requirements.
This phase involves collaboration between procurement specialists and engineers. By working together, we ensure that every component—from actuators to control valves—is perfectly suited to the system's needs. Our commitment to quality at this stage sets the tone for the entire build process.

Curious about selecting the best components for your hydraulic system? |
Once we've sourced the best components, it's time to bring the system to life by laying out each part for maximum efficiency.
Each HPU is unique, and design considerations play a critical role in its success. With these considerations in mind, once the components are in place, our skilled technicians take over.
Each of our technicians has a personalized workstation built with aluminum extrusion and featuring a 32-inch monitor. This setup allows them to access and interact with 3D project drawings, allowing them to rotate, zoom in, and zoom out to understand every detail of the layout. They also have a direct line of communication with engineers and project managers, ensuring seamless collaboration on each system.

After finalizing the layout and ensuring every component is perfectly positioned, our skilled technicians are ready to bring the unit to life.
This next phase, the assembly, is where precision and craftsmanship come together to create a fully functional hydraulic power unit.
The assembly process involves piecing together components and closely monitoring fitment and design. Attention to detail is paramount. If the system includes a manifold, it is typically assembled and removed before painting to ensure longevity. Custom paint thicknesses are applied as needed, contributing to the unit's durability and appearance.

After precise assembly, the next step is crucial—protecting our hard work with a durable coating that ensures longevity and performance.
To ensure durability, we meticulously prepare each system for coating by cleaning it thoroughly to remove any impurities or contaminants. Our standard two-part epoxy paint, known for its exceptional adhesion and durability, is applied precisely.
We offer an extensive range of custom colors based on customer specifications, allowing for personalization and alignment with brand identity. After applying the paint, we thoroughly check its thickness using advanced measurement tools to ensure it meets specific industry and client requirements, guaranteeing both functionality and aesthetic appeal.

Manifold Assembly
If your project involves manifolds and is made of aluminum, we initially assemble the manifold but remove it before painting. The crucial step is inspecting the manifolds to ensure they are clean and free of burrs or debris. Once cleared, we proceed with the assembly. The complete manifold is then subjected to functional testing during the system run.
With a durable coating applied to protect against harsh conditions, it's time to integrate the brains of the operation—electrical systems that bring precision and control to every hydraulic power unit we produce. In this next phase, our electrical team carefully installs the wiring and control mechanisms to ensure seamless operation.
Our control systems adjust in real-time, giving you peace of mind that your system is always running smoothly. So, after the coating is done, our electrical team gets to work on integrating the enclosure and running all the necessary cables.
Setting up an electrical system requires a close attention to detail and many years of experience. It’s all about fine-tuning control mechanisms. This means setting switches and adjusting each component to guarantee optimal functionality.
With the electrical setup complete and all control systems in place, it's time to ensure everything works flawlessly. In the testing and calibration phase, we put every component to the test to verify that the hydraulic power unit performs precisely as intended, providing the reliability our customers count on
We rigorously test each component to ensure 100% functionality, employing thorough procedures and technology to guarantee reliability and performance. Utilizing calibrated test equipment and comprehensive data logging, we provide our clients with detailed, accurate performance data, offering insight into every aspect of the system’s operation.
We offer in-person or virtual witness tests to allow customers to observe their unit’s testing from anywhere in the world. This significantly saves time and reduces travel costs while ensuring their peace of mind. Customers can request specific adjustments that ensure the final product is tailored precisely to their needs.
Once testing is complete, we meticulously document the results to provide customers with a comprehensive record of the system’s capabilities. This documentation includes performance specs, safety verifications, and any certifications required for compliance. After a final safety check and inspection by our shop foreman and quality assurance team, the hydraulic power unit is ready for delivery.
Once testing and calibration confirm that every component is functioning at its peak, we’re ready to prepare the unit for its journey to you. In the final stage, our packaging team carefully crates the fully assembled system, ensuring it arrives in perfect condition and ready for seamless integration
Our custom packaging team meticulously crates the fully assembled and verified hydraulic system. Our lumber is heat-treated and stamped for overseas shipments, allowing us to ship globally.

For orders with multiple systems, whenever possible, we employ batch building. While this approach varies by project, it often yields savings not only in construction but also during testing.
Setting up for a test once allows us to switch between systems efficiently, significantly reducing testing time. Initial setup of a test circuit can take a few hours as we ensure comprehensive testing of all components. Setting up once simplifies the process of merely disconnecting and connecting each system, saving considerable time.

Considering multiple systems? |
We design each HPU with energy efficiency and top performance in mind, tailoring it to specific pressure and flow needs. Using advanced SCADA systems and IoT-enabled sensors, we continuously track real-time data on pressure, flow, and temperature, allowing us to fine-tune systems for maximum efficiency.
This proactive monitoring not only minimizes component wear but also extends the system lifespan and reduces costly downtime. By integrating AI-driven predictive maintenance algorithms and leveraging the latest innovations in hydraulic technology, we ensure our HPUs consistently exceed ISO 9001 standards for quality and reliability.
Like any process, you're going to run into some challenges. While building hydraulic power units, we encounter challenges such as supply chain delays, which can impede progress and lead to project setbacks. Our solution is to work closely with our preferred vendors, establishing strong relationships and maintaining flexibility in sourcing local components to mitigate any disruptions.
Choosing the right partner for your hydraulic power unit project makes all the difference in your operations. At Airline, we combine expertise, innovation, and dedication to deliver HPUs that enhance performance and reliability.
