Generator set range
Specify the generator around the duty, site and load.
Patsons engineers and assembles diesel generator sets from 100 to 3,000 kVA for prime, standby and project power. Each package is configured around the required duty, ambient conditions, electrical output, acoustic target, controls and service access.
Configuration
One generating set, engineered into the right package
The engine and alternator are only the starting point. Airflow, fuel autonomy, controls, noise, transport, maintainability and integration determine whether the installed system performs as intended.
Open generator sets
Skid-mounted packages for dedicated plant rooms, protected industrial spaces and projects where the building provides the enclosure.
Sound-attenuated sets
Weather-protected acoustic canopies with service doors, ventilation paths and silencing selected around the site noise target.
ExploreContainerized systems
Large packaged systems with integrated ventilation, exhaust, fuel, control and maintenance provisions for critical installations.
ExploreTransportable packages
Trolley-mounted or project-specific transportable sets for changing work fronts and temporary operating locations.
Selection bands
A practical way to start the capacity conversation
The bands below organize the Patsons project range. They are not a substitute for a load study. Motor starting, nonlinear loads, step-load acceptance, ambient temperature and future expansion can materially change the final selection.
| Indicative band | Typical project context | Engineering focus |
|---|---|---|
| 100–500 kVA | Commercial buildings, workshops, site facilities and smaller industrial loads | Starting current, footprint, fuel autonomy and acoustic limits |
| 625–1,500 kVA | Industrial plants, large developments, marine and infrastructure packages | Load steps, heat rejection, controls, logistics and service access |
| 1,600–3,000 kVA | Critical facilities, major industrial loads and multi-set power plants | Parallel operation, redundancy, ventilation, exhaust and system-level testing |
Core components
Built around established engine, alternator and control platforms
Project specifications can be developed around established diesel engine platforms including Perkins, Cummins, Baudouin and Volvo, paired with alternators such as Stamford or Leroy-Somer. Availability and the approved project vendor list determine the final combination.
Patsons integrates the mechanical package, electrical controls, base frame, cooling, fuel, exhaust and enclosure requirements into one coordinated build. A clear bill of materials and approved drawings keep the package reviewable before fabrication begins.
- Prime or standby duty and site-specific derating
- 380–415 V at 50 Hz or project-specific electrical output
- 1500 or 1800 rpm configurations where applicable
- Manual, automatic or synchronizing control architecture
- Base tank, day tank or external bulk-fuel interfaces
- Factory and site testing aligned to the agreed inspection plan
Project workflow
From load information to commissioned power
- 01
Define
Confirm load profile, duty, site conditions, voltage, frequency, acoustic target, autonomy and compliance requirements.
- 02
Engineer
Select the generating set and develop the package layout, controls, ventilation, exhaust, fuel and interface drawings.
- 03
Assemble
Fabricate and integrate the approved package with documented component and workmanship checks.
- 04
Test
Complete the agreed functional and load-bank tests, close observations and prepare project records.
- 05
Commission
Coordinate delivery, installation interfaces, start-up, site testing and operator handover.
Frequently asked questions
Technical questions, answered clearly
Final selections and compliance are confirmed against the project specification and approved technical submittal.
What generator capacities does Patsons Energy manufacture?
Patsons develops generator projects from 100 to 3,000 kVA. The exact available prime or standby rating is confirmed against the selected engine, alternator, frequency, voltage and site conditions.
Can a generator be supplied for 50 Hz or 60 Hz operation?
Yes. Patsons can configure projects for 50 Hz or 60 Hz applications, subject to the selected engine speed, alternator, voltage and project specification.
Do you supply open and soundproof generator sets?
Yes. Available package formats include open skid-mounted sets, sound-attenuated canopies, transportable packages and containerized systems.
How is the correct kVA rating selected?
Selection starts with the connected and running load, the largest motor or load step, duty, ambient conditions, power factor, harmonic loads and required redundancy. Patsons reviews those inputs before confirming a rating.
