The automotive industry with energy-efficient processes
In the automotive industry, energy efficiency, availability, and process stability are key to competitiveness. In automotive manufacturing, thermal process control determines productivity, energy consumption, and availability—from injection molding and die casting to coating/painting, test benches, and end-of-line processes.
ONI provides comprehensive system solutions (consulting, planning, construction, service) that combine industrial refrigeration, (mold) temperature control, ventilation/air conditioning, water treatment, and heat recovery into a scalable, standards-compliant integrated system.
This delivers operational benefits such as: reducing cycle times, stabilizing quality, and measurably lowering energy costs.
- A trusted partner and single point of contact reduces interface risks and delivers measurable performance and energy efficiency gains while ensuring maximum system availability (ISO 9001/14001/50001)
- Comprehensive packages with certifications, references, and clear TCO logic reduce procurement risk and the need for renegotiation
- Rapid payback through heat recovery/temperature control benefits, grant support, and scalable rollouts across multiple locations
- Productivity: Shorter cycles, more consistent quality, less scrap
- Costs & Climate: Significantly reduced energy/operating costs, CO₂ reduction
- Security: Reliable 24/7 service, references & certifications
We begin with an on-site analysis of your load profiles, plant conditions, and process requirements—from which we identify weaknesses, bottlenecks, and opportunities for savings, and, if necessary, prepare a feasibility study to serve as a reliable basis for decision-making
Further project steps:
- Concept & Design (system logic, control strategy, integration into existing equipment)
- Subsidy/Regulatory Check (BAFA/EnEfG requirements, refrigerant roadmap)
- Technical Concept + ROI (Temperature Control, Refrigeration, Heat Recovery; Variant Comparison)
- Pilot cell → Rollout with 24/7 service and performance monitoring
- Optional extension with long-term monitoring and regular optimizations to ensure long-term efficiency and availability
Simultaneous demand for cooling and heating – waste heat often goes unused
Automotive facilities have parallel cooling needs (processes, buildings, test areas) and heating needs (heating, hot water, drying/cleaning processes). From an energy perspective, it is problematic when waste heat from refrigeration, compressors, or process exhaust air is “cooled away” while heat is generated using fossil fuels elsewhere. ONI positions itself precisely at this intersection through heat recovery and systemic optimization.
Load Peaks & Grid Restrictions (Power Prices, Connection Limits, Peak Events)
Production start-ups, shift changes, and numerous drives, compressors, and refrigeration systems generate high 15-minute power peaks—which are costly due to grid fees and power prices and pose a critical challenge when grid capacity is limited. For customers, this directly hinders cost efficiency and scalability.
Energy-intensive process cooling as a continuous load (24/7 load)
In automotive and supplier plants, many processes run continuously and require a stable supply of cooling water and refrigeration (e.g., injection molding, machining, test benches, power electronics testing). The key to energy savings often lies not in individual machines, but in the overall system technology (hydraulic/machine cooling circuits, recirculation cooling, pump operation, control systems, partial load).
Process stability through precise temperature control – energy efficiency must not come at the expense of quality
Automotive manufacturing (including e-mobility) is extremely quality- and cycle time-driven: Temperature deviations cause scrap, rework, or downtime. Customers therefore require precise and reproducible temperature control while simultaneously reducing energy consumption. In its public image, ONI emphasizes precisely this combination of energy efficiency and process optimization.
