※Key specifications to consider when making a selection.

Ultra-low noise diesel generators are designed for high-risk environments where environmental protection, power versatility, and operational durability are critical. As part of the Eco-Base series, leak prevention mechanisms are directly integrated into the chassis.

※Key specifications to consider when evaluating and selecting equivalent products.

This document explains the key specifications and specific comparison candidates that should be considered when evaluating and selecting an "equivalent" product to the Denyo DCA-60LSIE. When selecting an equivalent product, it is not enough to simply have a "60kVA output"; it must also meet three other criteria: **"Eco-Base (integrated oil containment dike)", "ultra-low noise", and "compliance with the third stage of exhaust gas regulations"**.

Please consider the same quality for optional accessories.

**Purpose of this requirement/Mission Impact if we don’t get**

The purpose is to maintain the function of drainage pumps during power outages or disasters, and to prevent sewage backflow and flooding onto the ground.

The generators will be used in support of sewer lift stations. One in Naha Military Port and the other in Torii Station. Without generator support during extended power outage such as typhoon event can cause sewerage to overflow and cause environmental concerns especially Naha Military Port.

This is an "emergency backup power supply" designed to maintain power supply during sudden power outages or disasters. In addition to the functions of a standard manual generator, it is equipped with a "water level sensor-linked automatic start/stop system."

This ensures reliable power supply and safe shutdown even in completely unmanned environments by operating only when the water level rises during a power outage and stopping when it is low. It automatically controls the ON/OFF of the power supply without human intervention. This prevents unnecessary fuel consumption and supplies power only when needed.

Regarding salt damage countermeasures for emergency generators and their eƯectiveness, corrosion-induced electrical and engine problems are significantly reduced, resulting not only in extended lifespan but also in substantial benefits in terms of operating costs and reliability. Furthermore, in pursuing eƯiciency in "maintainability" and "installation," mounting emergency power supplies on two-wheeled trailers is crucial not only for emergency response but also for dramatically reducing costs and risks.

In the event of a power outage or disaster, the loss of power to drainage pumps significantly delays the installation of emergency generators and the deployment of personnel, which is one of the most serious factors causing secondary damage in facility management.
