Note: Artist’s conception.
An ion generator manufactured in Japan is mounted on top of the car. Nano-sized electrostatic atomized water particles work to improve air quality.
Testing organization: Hitachi Power Solutions Co., Ltd.
Testing method: Verification using six-rank odor intensity indication method in passenger elevator with 13-person capacity Deodorizing method: Release of ionized particles
Subject: Methyl mercaptan was released and the change in its concentration was measured.
The ionized particles released into the air come into contact with odor molecules and the OH radicals break down substances that cause odor. 1 Also, the ionized particles come into contact with allergens (pollen 2 and mites 3 ), bacteria, 4 and viruses, 5 and the OH radicals denaturize their protein and suppress them.
Note: The ionized particles suppress viruses, etc., but they are not guaranteed to prevent infection.
Note: The ion generator is not available in the following cases:
(1) When the ceiling is supplied by the customer.
(2) When the car internal depth is 1,250mm or less.
Measures such as control to suppress motor vibration and vibration-absorbing type guide shoes are utilized. These reduce noise and vibration when the elevator is in motion for a smooth and quiet ride.
