Stationary emergency power generators for industrial use (Stage I–III)

What are stages? I–III emergency power generators?

Our stationary emergency power generators of the emission levels Stage Stage I to Stage III are robust diesel generators for industrial use, where Reliability, availability and cost-effectiveness are the focus. Unlike modern stages V-solutions are coming to the stage I-III units without complex exhaust aftertreatment – ​​ideal in non-emission zones, in which no stricter limits are required.

With a range of services from 5 to 2,500 kVA The generators cover a wide range of applications – from supplying power to small consumers to providing backup power for large industrial plants. The generators are based on the professional continuous use as an emergency power or backup power system designed to offer maximum operational reliability, even under demanding environmental conditions.

Who are Stage suitable for? I–III emergency power generators?

Stage I–III emergency power generators are primarily aimed at industrial and commercial operatorsThose who require a reliable backup power supply but operate in areas where stricter emission standards are not mandated. Typical target groups include:

• industrial companies with a need for stationary emergency power systems for production, logistics, storage or critical infrastructure
• Companies with their own factory network, which must ensure continued operation in the event of a power outage
• Construction and raw materials companies, which secure remote locations or facilities with emergency power systems
• Large agricultural enterprises with sensitive technology (e.g. B. Cooling, ventilation, feeding systems)
• Operators of technical centers (e.g. B. cold storage facilities, pumping stations, energy suppliers), for which shutdown is not an option

For these operators, the most important factors are... Availability, simple technology, robust design and predictable costsStage plays right here. I-III aggregates demonstrate their strengths – especially when no complex emission certificates or stage V requirements must be met.

Advantages of stationary emergency power generators in industrial applications

Stationary emergency power generators from GRAEFER MASCHINEN are designed to provide power in an emergency. immediately and reliably to be available – and to keep maintenance and operating costs as low as possible during normal operation.

• Long-term tested industrial motors for professional continuous and emergency power operation
• Well-known generator manufacturers (e.g. B.Stamford, Mecc Alte, Linz Electric)
• Made in Italy according to strict quality and manufacturing standards
• High operational reliability even under harsh industrial and environmental conditions
• Simpler technology compared to complex exhaust aftertreatment systems (no AdBlue, fewer components)
• Good availability of spare parts for motors, generators and control components
• Full configurability regarding control, connections, tanks, soundproofing and installation

The result: High availability with moderate investment – especially for operators looking for a robust emergency power solution without unnecessary complexity.

Areas of application && Emission requirements

Stage I-III emergency power generators are primarily used where no stricter emission requirements apply or where the facilities in areas not publicly regulated be operated – for example:

• In-house emergency power supply in industrial and logistics sites
• Factory networks on company premises without special environmental zones
• remote locations with island operation and no public access for residents
• Agricultural and commercial applications outside sensitive areas

In new projects and especially when deployed in environmental zones, inner-city areas or public tenders Operators must check whether Stage V or other stricter regulations apply. In many industrial indoor areas and classically unregulated zones, Stage However, I-III aggregates remain an extremely attractive economic option.

Performance ranges from 5–2,500 kVA and typical applications

GRAEFER MASCHINEN's stationary emergency power generators cover a performance range of 5 to 2,500 kVA This allows almost all typical scenarios in an industrial environment to be represented.

Smaller services (approx. 5–80 kVA)

• Emergency power supply for smaller buildings, offices, control rooms or IT infrastructure
• Securing individual machines, pumps or ventilation systems
• Compact emergency power systems for smaller businesses

Average performance (approx. 80–800) kVA)

• Emergency power for production lines, warehouses and logistics centers
• Supply of larger building complexes and technical facilities
• Factory networks with partial power supply in case of power failure

High performance (approx. 800–2,500 kVA)

• Securing critical infrastructure and large facilities
• Emergency power concepts with multiple synchronized generators and load distribution
• Large industrial or utility projects with high starting currents and peak loads

In many projects several units combinedto achieve redundancy and maximum availability. Synchronous operation and load sharing are part of the standard repertoire.

Technology && Configuration: Motors, generators, control

As with our stage V-series units are also available at the Stage. I–III emergency power generators Industrial-grade technology and high configurability in focus.

Industrial motors from leading manufacturers

Stage is used I-III compliant industrial engines from well-known manufacturers, for example Perkins, Yanmar, Kohler, Deutz, Baudouin, FPT Iveco, Cummins, Volvo, Scania, Hyundai or Mitsubishi. These engines are:

• for Continuous operation and emergency power operation designed
• fuel-efficient in typical load ranges&
• with good spare parts availability supported worldwide

Generator brands freely selectable

With the generators you can... a. between Stamford, Mecc Alte, Linz Electric and other manufacturers. This allows the units to be optimally integrated into existing infrastructures, factory standards or existing fleets.

steering && interfaces

The control system has a modular design and can be precisely tailored to your emergency power concept:

• Genset controller with freely programmable logic
• CAN bus (J1939), Modbus RTU/TCP for integration into control systems and building automation

economy && Total Cost of Ownership (TCO)

For industrial operators, the Overall economic efficiency over the life cycle in focus. Stage I-III emergency power generators offer a significant advantage here if no stage is used in the application. V is mandatory:

• Lower investment costs compared to complex stages V-systems
• Simpler technology No SCR/DPF aftertreatment, fewer components, lower susceptibility to malfunctions
• Optimized operating costs thanks to fuel-efficient industrial engines
• Long service life through robust design and industrial-grade components
