CHP systems generate electricity while simultaneously capturing and using the heat produced during power generation. Where conventional generators convert only 35–40% of fuel energy into usable power, ElectroQuell CHP systems achieve overall efficiencies of 80–90% — dramatically cutting energy bills and carbon emissions.
Parallel systems connect two or more generators to operate as a single coordinated power source. Multiple units share the load — each running within its efficient range. If one unit fails or requires maintenance, the others carry the full load without interruption. Scale from a two-unit commercial setup to a complex multi-megawatt industrial power station.
The Duplex Series houses two complete generator sets in a single shared enclosure. One unit runs the load while the second stays on hot standby — ready to take over within seconds. The integrated digital control panel manages synchronization, load demand sensing, and run-time equalization automatically, without any external switchgear.
Stage V generators comply with EU Regulation 2016/1628 — the strictest emissions standard for non-road mobile machinery in Europe. With integrated DPF, SCR, DOC, and ASC aftertreatment systems, our generators are approved for urban emission zones and legally permitted across all EU construction sites, events, and infrastructure projects.
ElectroQuell trailer solutions transform generators into rapidly deployable energy hubs. Integrated trailers feature extended fuel tanks for 24–48 hours of autonomous operation, vibration isolation, and EU road compliance with full COC certification. Marco Mobile Units add precision on-site placement for congested locations where standard trailers cannot manoeuvre.

The ElectroQuell Duplex Series houses two complete generator sets within a single shared enclosure — delivering N+1 redundancy, fuel efficiency, and maintenance continuity in a footprint smaller than two separate installations.
The Duplex Series is a twin-generator concept: two fully independent generator sets — each with its own engine, alternator, and control system — sharing a common sound-attenuated enclosure and output busbar. The two units work together to provide continuous, redundant power from a single integrated system.
Both generators running: Full combined capacity available — ideal for peak load periods or maximum redundancy requirements.
One generator running: Standard operating mode — one unit carries the load while the second remains on hot standby, ready to start within seconds.
Alternating operation: The system automatically alternates between generators at configurable intervals — equalizing running hours and extending overall engine life.
The Duplex Series solves three of the most common challenges in backup power installations:
Problem: A large single generator running at low load risks wet stacking — unburned fuel deposits that damage the engine over time.
Solution: The Duplex system runs one smaller generator at optimal load, eliminating wet stacking while keeping the second unit on standby.
Problem: Two separate generator enclosures require significantly more space than a single unit.
Solution: The shared Duplex enclosure houses both generators in approximately 60% of the space required by two individual installations.
Problem: Servicing a single generator requires taking the entire backup power system offline.
Solution: With the Duplex Series, one generator can be fully isolated for maintenance while the other continues supplying power — no service interruption.
Scenario: Standard N+1 backup power
Generator A runs continuously, carrying the full facility load. Generator B remains on hot standby, monitoring the busbar. On failure of Generator A, Generator B starts and assumes load within seconds.
Scenario: High load or maximum availability
Both generators run simultaneously, each carrying 50% of the load. This mode provides the highest level of resilience — any single generator fault results in only a 50% load reduction, easily managed through load shedding.
Scenario: Equal runtime and maintenance scheduling
The control system alternates between Generator A and Generator B at programmed intervals — ensuring equal running hours, synchronized maintenance schedules, and maximum long-term reliability.
The heart of the Duplex Series is the Integrated Digital Control Panel — a smart computer that continuously analyses your facility's power needs and manages both generators automatically.
Automatic Synchronization: The system aligns voltage, frequency, and phase angle instantly. Both generators lock into step with the grid or with each other within seconds.
Load Demand Sensing: If load increases beyond the first generator's capacity, the controller automatically starts and synchronizes the second unit — without the lights even flickering.
Run-Time Equalization: The system tracks operating hours for each engine and automatically rotates the primary/secondary designation — ensuring both engines age at the same rate and extending overall system lifespan.
Healthcare & Life Safety: Hospitals and care facilities require continuous power without exception. The Duplex Series meets life-safety power standards with automatic, seamless generator transfer.
Data Centers & Colocation: Data centers demand concurrent maintainability. The Duplex Series delivers N+1 redundancy within a single system, simplifying infrastructure while meeting Tier III+ requirements.
Construction & Temporary Sites: For construction projects requiring reliable backup power in a compact, transportable form, the Duplex Series containerized units can be deployed and relocated efficiently.
Telecommunications: Telecom base stations and network infrastructure require 24/7 uptime. The Duplex Series provides the reliability and automatic failover essential for communications continuity.
Acoustic Enclosure: The shared enclosure provides sound attenuation for both generators simultaneously — reducing noise levels suitable for urban and residential adjacent sites.
Independent Circuit Breakers: Each generator has its own output circuit breaker and control panel, enabling complete electrical isolation of either unit without affecting the other.
Matched Alternators: Generator sets are matched with compatible alternators to ensure clean, synchronized parallel operation without waveform distortion or voltage instability.
Shared Weatherproof Enclosure: The common enclosure provides IP54-rated weather protection, integrated ventilation management, and optional climate control for operation in extreme temperatures.
Duplex Series configurations are available from 100 kVA to over 1 MVA total combined output. The two generator sets within the enclosure are typically matched in rating, with each unit contributing equally to the combined capacity.
While matched ratings are standard, asymmetric configurations are possible for specific applications. Our engineering team can design a Duplex system where Generator A handles base load and Generator B provides peak or emergency capacity, with appropriate control logic.
In most operating profiles, the Duplex system is more fuel efficient. Running one smaller generator at 70–80% load is significantly more efficient than running a single large generator at 30–40% load. The efficiency improvement varies by load profile but typically ranges from 10–25%.
