One-stop plant design

System design that reduces energy costs—and makes decision-making easier.

We develop a system concept tailored to your specific needs that combines cooling, heat recovery, and energy optimization. We place particular emphasis on a holistic approach that ensures both efficiency and sustainability. Our solutions are based on a sound decision-making framework to achieve optimal results for your business.​

Functional, easy to maintain, expandable

Design principles

A sound system design is based on operational requirements such as load profiles and space constraints. A detailed on-site analysis results in an integrated system that reduces operating costs and CO₂ emissions, minimizes interface risks, and supports grant eligibility—all tailored to current energy efficiency requirements.

  • Analysis & Potential Assessment: Recording of load profiles, temperature and media requirements, as well as efficiency and heat recovery potential as the basis for reliable planning.
  • “One-Stop” System Design: Combining all relevant disciplines into a compatible overall system with clearly defined interfaces.
  • Cost-Effectiveness & Funding/Compliance Package: Planning focused on ROI and TCO, including support for securing grants and compliance with regulatory requirements.

Why You Should Choose ONI

Everything under one roof

Intuitive system technology

  • 3D Detailed Design (CAD/3D Model) – From concept to three-dimensional detailed design for a “visual” representation of the system and improved coordination.
  • Trades Integration & Clash Detection – Integration of cooling energy, heating, HVAC, ventilation, cleanroom, and compressed air systems to prevent overlaps and clashes between trades.
  • Flow/Hydraulic Optimization – Focus on flow technology to reduce pump energy requirements and increase efficiency throughout the entire system.
  • Control & Remote Monitoring (Setpoints/Status Reports) – Process-optimizing control plus remote access: Read and evaluate status reports and adjust setpoints to detect deviations early.

Design

“Following a detailed on-site system analysis, we develop a system design that is precisely tailored to your operational requirements and integrates components such as air-cooled chillers, cooling towers, and refrigeration units into a unified, energy-optimized system.”

Design:

“We utilize state-of-the-art technology in our design process and handle every step of the design—from conceptual planning to 3D construction planning—across all disciplines to ensure that there are no overlaps or conflicts between cooling systems, heating, HVAC, ventilation, cleanrooms, or compressed air.”

Visualization:

“Thanks to the spatial (3D) and thus highly realistic representation of the plant engineering, you are already much better informed about the layout, interfaces, and project steps during the planning phase.”

A holistic approach instead of isolated solutions

Integrated approach to cooling, heating, HVAC, cleanrooms, and compressed air

A system can only function reliably over the long term if all components are considered together. In the system design phase, we take dependencies and interfaces into account early on—from generation and distribution to control and integration into your processes.

The result is a coordinated overall concept rather than isolated solutions: fewer implementation hurdles, clear responsibilities, and a system that can be efficiently operated, maintained, and expanded later on.
