With our revamping service, we modernize existing industrial plants in a targeted and efficient manner. Through modernization, retrofitting, and intelligent upgrades, we extend the service life of machinery, increase productivity, and sustainably reduce downtime.
Revamping brings existing plants up to the latest standards in terms of technology, safety, and energy efficiency—at significantly lower costs than building a new facility. This enables companies to sustainably improve the performance of their plants while they remain in operation.
Through structured analysis, modern engineering methods, and in-depth expertise, HAINZL lays the foundation for future-proof, efficient, and safe plants.
Revamping refers to the comprehensive modernization of existing industrial plants. Outdated components are replaced, hydraulic systems and control systems are upgraded, and modern automation is integrated. The goal is to bring plants up to the current state of the art in an efficient and cost-effective manner—without having to build new facilities.
Typical revamping and retrofit measures include:
// Replacement of outdated components with energy-efficient parts
// Modernization of hydraulic systems, valve technology, and safety devices
// Integration of modern automation systems for greater precision and process reliability
// Reduction of energy consumption through optimized drive and control technology
Targeted revitalization significantly extends the life cycle of plants and makes even older machines competitive again.
Revamping provides a decisive competitive advantage in many industries.
We specialize in the modernization of industrial facilities in the following sectors:

// Steel industry:
e.g., rolling mills, lubrication systems, hydraulic systems

// Woodworking industry:
e.g., presses, hydraulic systems, cylinders

// Energy and power plant technology:
e.g., turbine hydraulics, cylinders, control units

// Mechanical Engineering:
Production lines, test benches, automation systems
Building a new facility is costly, time-consuming, and logistically complex. In many cases, revamping or retrofitting is the significantly more economical and faster solution.
Your benefits at a glance:
// Lower investment costs through the use of existing plant structures
// Short downtime thanks to implementation during scheduled breaks
// Familiar operation and minimal training requirements
// Sustainability through energy-efficient components and processes
// Long-term spare parts availability and increased operational reliability

A revamping project follows a structured process that ensures efficient modernization with minimal downtime. Planning, coordination, and implementation are carried out transparently and in close collaboration with your operations. In this way, HAINZL transforms existing plants into high-performance, energy-efficient, and future-proof systems.
Detailed on-site analysis of the current state
Our engineering team analyzes the current condition of your system—from hydraulic systems, cylinders, and controls to safety and regulatory compliance, as well as energy efficiency and process parameters. The analysis identifies where revamping and retrofit measures will yield the greatest benefits.
Modernization concept & technical design
Based on the current status analysis, a customized revamping concept is developed, including defined replacement and retrofit components, energy-saving potential, and measures for modernizing the hydraulic and automation technology. Depending on your needs, several implementation options are available.
Planning & Prefabrication – Parallel to Ongoing Operations
While your plant continues to operate, key components such as hydraulic power units, valve blocks, control cabinets, and cylinders are prefabricated. This shortens installation times and ensures a smooth process.
Implementation during a planned shutdown
The modernization is carried out specifically during a planned shutdown—including disassembly, assembly, connection, and functional and safety tests. The result: significantly reduced downtime and a noticeably more reliable, energy-efficient plant.
