DENGUARD reduces electricity bills at your workplace.

World's first technology in electricity saving utilizer via electromagnetic wave noise control

Electromagnetic Wave Attenuation Technique

DENGUARD is a special ceramic plate that absorbs electromagnetic wave, and organizes them into stable waveforms to avoid unnecessary electrical loss.

Thermal Energy Conversion Technology

Heat is generated by the resistance of the current and by the collision of electrons and atoms, so DENGUARD prevents electricity loss due to heat generated when the electricity is moved.

Ensure Maximum Reliability

Soft ferrite, the main material in DENGUARD, is a non-burning material, so it keeps your business equipment safe.
