Denyo Quietest Generator, the Malie DCA-25MZ registers at only 43 decibels in sound emission under standard testing, and this finely-crafted generator operates at a noise level comparable to the silence you will feel in a quiet library.

In order to achieve such a feat, Denyo’s engineers stepped away from the conventional generator technology and re-imagined the overall structure of Malie Generator – from a whole new perspective and here are 4 points that contributed to the outstanding soundproofing capabilities of the Malie DCA-25MZ:

Dual Bonnet Structure

The re-designed canopy of the Malie DCA-25MZ generator is built with a Dual Bonnet Structure. The dual-layered structure is engineered to encase the engine, doubled with a thicker and softer acoustic insulator, to absorb noise effectively.

Dual Muffler & Resonator

Mufflers and Resonators work simultaneously to soften and eliminate specific sound frequencies. But unlike conventional generators, the Malie DCA-25MZ is designed with Dual Muffler and Resonator that has anti-vibration supports – arranged in pairs and positioned at strategic points to keep exhaust volume to the lowest level. Also, by changing the tone and louvres of the noise, the sound emitted from the engine changes and naturally sounded more favorable to the human ears.

Vibration Control

Do you know that vibrations caused by the engine can spread like a ripple effect to both the internal and exterior of the generator – which could produce uncomfortable noise and potentially damage the internal components? Equipping the Malie DCA-25MZ with a high-quality damper (shock absorber) helps absorb shock impulses and reduce the vibrations produced by the engine. Therefore, with the reduction of vibrations, noises are also greatly minimized.

Dual Electrical Fan

Engine cooling fan has been considered one of the sources of noise contributing to the noise emission, and inadequate airflow will cause the engine to overheat. Denyo recognized the issue and restructured the airflow dynamic by removing the engine fan and replaced with a dual electrical fan attached outside for a smoother ventilation system. Since electrical fans are not tied to the engine, it is significantly quieter and able to maintain at optimal speeds to cool down the engine efficiently and prevent internal overheating.

In this article, we have identified four key points that make Malie DCA-25MZ the Quietest Generator. It is ideal for powering activities such as events or healthcare facilities where quietness is required, apart from the usual industrial and construction applications that Denyo has traditionally been associated with.
