Diesel Generator Sets

The OnPower Diesel Generator Sets can be silenced in Canopy or opened, and are designed to provide electrical power for supply with a three-pole fixed circuit-breaker on the base, controller and their accessories. All generator sets are prepared for the synchronization system between Group and Network.

The Diesel Generator Sets are easy to handle and adapted for hard reach places. Our experience in Latin America, over 18 years, allowed the creation of an unique product, with an uselife above the market and adapted to all Market Segments.

Woodward EasYgen-400/600/3000.

The numerous inputs and outputs, along with a modular software structure, allow you to use the easYgen series in a wide variety of applications. This includes stand-by, AMF, peak shaving, import-export, cogeneration or distributed generation, among others. In addition, the easYgen series is compatible with island, island parallel, mains parallel and multiple unit mains parallel operations.

OnPower Differentials

  • Fuel tank in carbon steel, installed in the base of the fairing, with indication of local level, in the capacity of 250 to 820 liters. Easy removal for maintenance and cleaning, without the need to remove the motor.
  • Silent acoustic term and elastic segment, mounted internally in the fairing.
  • Vibration dampers with metal body, shear resistant, mounted between motor, generator and base.
  • 150 Ah starter batteries mounted on the base with a holder, cables and connectors.
  • Superior access for crane lifting and lower access for forklift lifting.
  • Supply made in a safe way, away from the power plants.
  • Output and Input cable connectors on both sides of the generator set, allowing better access without moving the equipment.
  • Ventilation openings on opposite sides (fairing machines) allowing easy installation and adaptation to hard to access locations.
  • Ladder with easy and safe access to the top of the generator set.
  • Automatic transfer board included (optional).

COP, Stand By ou Prime

Stand By Power

Stand By emergency power is the maximum power that a generator set is able to provide, for variable loads, during the supply interruption energy provider period, up to 200 hours per year, confirmed by ISSO 8528.

Prime Power

It is available for an unlimited number of annual hours under variable face condition, in accordance to ISO 8528-1. An overload capacity of 10% is allowed for 1 hour every 12 hours of operation, in accordance to ISO 3046-1.

COP Continuos Power

Continuous linear systems for continuous operation with constant loads. It is aimed to feed loads in the lack of Network, whose demand curve can be considered linear, that is, without significant variation over time during power supply, according to ISO 8528.
