An Open Type Generator is a diesel generator set designed without a soundproof enclosure or canopy. It features an exposed engine, alternator, control system, and steel base frame. Because of this open-frame structure, it is typically installed in environments where noise control is not the primary concern.
Unlike silent generators, the Open Type Generator provides easy access to internal components, making maintenance and servicing faster and more cost-effective.
Most Open Type Generator systems consist of:
Engine – Four-stroke, water-cooled, intercooling diesel engine
Alternator – Brushless excitation system with AVR (Automatic Voltage Regulator)
Control & Protection System – Microprocessor-based controller
Steel Foundation – Shock-absorbing structure with optional bottom oil tank
These components work together to deliver stable frequency, fast transient response, low emissions, and reliable power output.
The Open Type Generator is widely used in industries where durability, power output, and cost-effectiveness are prioritized over noise reduction.
Construction environments demand high-power output and rugged durability. An Open Type Generator powers:
Excavators
Tower cranes
Aerial work platforms
Concrete mixers
