Product catalog summary
Overview: The document introduces the Mālie soundless generators, models DCA-45MZ and DCA-25MZ, highlighting their ultra-quiet operation with sound levels as low as 43-44 dB, comparable to a library environment. These generators are designed for noise-sensitive areas such as residential zones, hospitals, and schools.
Key Features:
  • Noise Reduction: Achieved through the use of electric fans instead of engine fans, dual pipe mufflers, and a double-structured hood to minimize noise leakage.
  • Vibration Control: Utilizes vibration-proof materials and structures to suppress engine vibrations.
  • High Performance: Equipped with intensified damper wiring to reduce waveform distortion and voltage fluctuation, making them suitable for sensitive equipment and event lighting.
Operability and Maintenance:
  • Functional arrangement of operation switches and meters for ease of use.
  • High-visibility digital engine monitor included as standard.
  • Easy maintenance with wide-opening front panels and sliding or double doors for access.
Safety and Eco-Friendliness:
  • Equipped with earth leakage relays and circuit breakers for safety.
  • Automatic safety controls for engine shutdown under abnormal conditions.
  • ECO-BASE body designed to separate and manage oil and water, with easy drainage and maintenance features.
Specifications: Detailed specifications include engine type, fuel consumption, power output, dimensions, and compliance with ISO 9001:2015 and ISO 14001:2015 standards.

DCA-MZ Malie series-2

To the Next of "Ultrasilent" The sound level of the silent generator Mālie* is only 43 to 44 dB. It is said to be as quiet as the sound in a library. In recent years, consideration for sound and noise has been required, such as in residential areas, hospitals, and near schools. Denyo has been continuing to challenge the development of quieter generators even by 1 dB. The silent generator Mālie, which is completed with our original soundproof design technology and many years of expertise, is even quieter than the ultra-low noise type and super ultra-low noise type. Denyo's technology has evolved...

DCA-MZ Malie series-4

Equipped with High Performance Generator Power Generators with Less Waveform Distortion and Voltage Fluctuation With their intensified damper wiring, our generators are less vulnerable to waveform distor tion, even when the load applied to the rectifiers changes. They are also highly resistant to negative-sequence current. Moreover, since they can restric t voltage fluc tuation, they can resist inver tor load, thyristor load, and computer control load. They are suitable for lighting at event sites, precision apparatuses, and measurement equipment. Generators with better Motor Activation The transient...
