Overview

Denyo believes that life would be so much better if you could hear all the colours. Therefore, a line of Quietest Denyo Generators is designed to allow diesel generators in situations such as on-location filming and symphony orchestras, where quietness is strictly required. The most notable addition is the Malie DCA-45MZ generator, which emits a sound level of 44 decibels* comparable to the quiet ambience experienced in a library.

To achieve this level of quietness on the more extensive Malie DCA-45MZ, Denyo stepped away from conventional generator technology and reimagined its structure into a design that is one of a kind. Here are three (3) fast facts about Malie DCA-45MZ that you should know:

*Measured at 50Hz high speed, no load operation and 7-metres away from the source.

Airflow to Optimize Soundproofing Capability

Unlike conventional generators, the Malie DCA-45MZ generator is designed with a dual bonnet to effectively contain the engine’s noise. However, due to the larger capacity of the Malie DCA-45MZ, its engine tends to produce more vibration and noise than its smaller counterpart (Malie DCA-25MZ).

Therefore, Denyo engineered the first-of-its-kind dual bonnet system, which enables an air gap between the outer and inner bonnets, allowing airflow to travel within. As a result, the travelling airflow significantly improved airflow dynamics within the generator, for efficient ventilation and doubled as an invisible soundproof wall that absorbs any direct noise transmission from the engine.

Finest Materials for Durability and Performance

To achieve superior durability, the canopy of the Malie DCA-45MZ goes through a series of stringent processes – including cationic electrodeposition coating treatment that major automobile manufacturers adopt to achieve corrosion resistance and the highest level of weatherproof quality.

Quality materials are essential for quality results. Therefore, trials were carried out on various sound-insulating materials, and Denyo selected only the best for the Malie DCA-45MZ. The comparison images show that the sound-absorbing insulator (foam) used in Malie DCA-45MZ is thicker and firmer, also layered in two levels to enhance the overall acoustic absorption coefficients.

Designing for Safety and Usability

Aside from innovations and the finest acoustic insulation materials that mitigate noise, Denyo took careful consideration in designing the canopy of the Malie DCA-45MZ for the safety of its users. Unlike any other generators on the market, the Malie series is designed with curved and smooth edges on all corners, which drastically reduces the likelihood of users injuring themselves during transportation or maintenance.

Conclusion

By breaking the limitations and assumptions of conventional engineering norms and manufacturing processes, the result is a finely crafted Malie DCA-45MZ generator that purposefully serves the niche environments and communities with low noise threshold, apart from industrial and construction applications Denyo has traditionally been associated with.
