Open Type Diesel Generator Sets Industry knowledge

Yangzhou Aiweite Electromechanical Co., Ltd. builds open type diesel generator sets from 10 kVA to 2500 kVA on a single integrated base frame, combining engine, alternator, radiator and controller into a fixed installation platform. As a China Open Type Diesel Generator Sets manufacturer, we supply these units for factory generator rooms, industrial and mining sites, remote field projects and central power stations where ventilation is available and noise limits are moderate.

What an Open Type Diesel Generator Set Includes

An open type set is the standard genset configuration without a silent canopy or outer enclosure. The engine, alternator, radiator, controller and base frame remain fully exposed, which keeps heat paths short and gives maintenance personnel direct access to every service point. The structure suits fixed indoor installation or well-ventilated outdoor positions protected by a separate weather shelter.

Because there is no enclosure to restrict layout, the open frame reserves space for larger fuel tanks, parallel control cabinets and remote monitoring modules. This expandability is why open type units are commonly selected for multi-unit power stations and for projects that may add capacity in later phases.

Power Range and Engine Options

Our open type range covers 10 kVA to 2500 kVA. Within that span we assemble sets around Cummins, Perkins, Weichai, Yuchai, Baudouin, MTU, Volvo, SDEC and Mitsubishi engines, matched to alternators and controllers selected for the required voltage, frequency and load profile.

Power Band Typical Open Type Application Configuration Focus
10 – 100 kVA Workshops, small plants, standby for commercial buildings Compact base frame, manual or auto start panel
100 – 400 kVA Industrial parks, municipal facilities, processing plants AMF/ATS integration, larger fuel tank options
400 – 1000 kVA Mines, chemical plants, remote construction sites Heavy-duty base frame, remote monitoring readiness
1000 – 2500 kVA Central power stations, multi-unit parallel operation Parallel control, load sharing, synchronizing panels

Engine selection is matched to the duty profile. Standby service, prime power and continuous operation place different demands on cooling capacity, fuel system layout and governor response, so we confirm the working point before fixing the engine model.

Where Open Type Sets Fit Best

  • Indoor fixed generator rooms: factories, industrial parks and municipal facilities with on-site ventilation and noise reduction measures.
  • Industrial and mining sites: mines, chemical plants and processing workshops where noise restrictions are loose and airflow is good.
  • Remote field projects: construction sites, highway and railway engineering where maintenance access matters more than appearance.
  • Central power stations: large installations using multiple units in parallel, where open frames simplify inspection and capacity expansion.
  • Customization projects: reserved internal space supports explosion-proof, anti-corrosion and large fuel tank upgrades.

Open type units are not intended for noise-sensitive locations such as residential communities, schools or hospitals, and they require a separate shelter if installed outdoors. Where those conditions apply, our Silent Type Diesel Generator Sets or Container Type Diesel Generator Sets provide the appropriate enclosure.

Specifications That Shape the Configuration

Open type sets are specified around the electrical and thermal working point rather than around enclosure dimensions. The following parameters determine the final build:

  • Rated power and duty: standby, prime or continuous rating in kVA and kW at the site ambient temperature.
  • Voltage and frequency: 380–415 V / 50 Hz, 440–480 V / 60 Hz or other required combinations, with reconnectable alternator options.
  • Cooling: radiator-mounted cooling matched to ambient conditions, with remote radiator arrangements where the room layout requires it.
  • Control and protection: manual, auto start, AMF or parallel control panels with the protection set required by the installation.
  • Fuel autonomy: base tank or separate day tank sized for the required running hours between refills.
  • Exhaust and ventilation: exhaust routing, silencer selection and room air intake/exhaust sizing coordinated with the building services.

Sets are assembled to ISO 8528 industrial standards. Where a project calls for a specific engine brand, we build around the corresponding platform, including Cummins Powered Diesel Generator Sets and Perkins Powered Diesel Generator Sets.

Controls, Automation and Parallel Operation

Control panels are configured around the required line interface. A basic auto start panel covers mains failure start and shutdown; an AMF panel adds automatic transfer switching; a parallel panel adds synchronizing, load sharing and load-dependent start/stop for multi-unit stations.

Remote monitoring modules can be added to the open frame without enclosure modification, which allows later integration with building management or SCADA systems. We confirm the communication protocol, alarm set and metering points before the panel is built.

Installation, Commissioning and Acceptance

Open type sets are delivered on an integrated base frame with anti-vibration mounts. Installation requires a level foundation, adequate room ventilation, exhaust routing to atmosphere and correct cable entry to the control panel. We provide dimensional drawings and terminal information so the site team can prepare foundations and cable routes in advance.

Commissioning covers no-load and load testing, protection setting verification, governor and voltage regulation checks, and, where applicable, parallel load sharing tests. Acceptance documentation follows the agreed test schedule, and operating and maintenance manuals are supplied with the unit.

Quality Control Through Production

Aiweite has manufactured and installed generator sets from 1 kVA to 2500 kVA since 2008. Advanced manufacturing equipment and strict quality management are applied throughout production so that each set meets applicable international standards. Engine, alternator and controller components are checked against the confirmed configuration before assembly, and each completed set is run before dispatch.

Maintenance and Serviceability

The open structure is the main serviceability advantage: filters, belts, hoses, sensors and electrical connections are reachable without removing panels. Daily checks, oil and filter changes, coolant inspection and battery maintenance follow the engine manufacturer's schedule, and the exposed layout shortens fault-finding time.

Spare parts support follows the engine and alternator platforms used in the build. We keep the configuration record for each set so that replacement parts can be identified from the serial number.

Information We Use to Configure Your Solution

To prepare a configuration and quotation, we work from the project data below. Missing items are confirmed during technical review rather than assumed.

  • Required power rating, duty class and site ambient temperature
  • Voltage, frequency, phase and whether the alternator must be reconnectable
  • Preferred engine brand, if specified, and any emission requirement
  • Control mode: manual, auto start, AMF, parallel or remote monitoring
  • Fuel autonomy target and tank arrangement
  • Installation environment, ventilation and exhaust constraints
  • Site altitude, seismic or corrosion conditions affecting materials
  • Documentation, testing and acceptance requirements

Frequently Asked Questions

Can an open type set be installed outdoors?

Not directly. Exposed components have no dust, rain or sun protection, so an outdoor installation needs a separate weather shelter or a switch to a container or silent type unit.

What power range do you build in open type configuration?

We build open type sets from 10 kVA to 2500 kVA, with engine platforms including Cummins, Perkins, Weichai, Yuchai, Baudouin, MTU, Volvo, SDEC and Mitsubishi.

Can the set be upgraded for parallel operation later?

Yes. The open frame reserves space for parallel control cabinets and synchronizing equipment, so a single-unit installation can be extended to a multi-unit station in a later phase.

How is noise handled if the site has limits?

Open type sets have no sound insulation. Where noise limits apply, we supply silent type or container type sets instead, or the site provides acoustic treatment for the generator room.

What documentation is supplied with the unit?

Each set is delivered with operating and maintenance manuals, a configuration record and the test documentation agreed for the project.
