MHI Air-Conditioning and Refrigeration Announces 2019 Models of "roomist" Humidifier Lineup
5 Fan-powered Steam Units and 3 Hybrid Evaporative Warm-mist Systems

- 350 and 600ml/h fan-powered steam models feature water level window and aroma therapy fragrance tray
- Two types: energy-saving hybrid evaporative warm-mist systems and easy-to-maintain fan-powered steam systems

TOKYO, Sept 9, 2019 - (JCN Newswire) - Starting September 9, Mitsubishi Heavy Industries Air-Conditioning and Refrigeration Corporation, a Group company of Mitsubishi Heavy Industries, Ltd. (MHI), will progressively launch its 2019 lineup of eight "roomist" humidifiers for the Japanese market. The new lineup with consist of five fan-powered steam units designed for easy operation and engineered for outstanding energy savings and quiet operation; and three hybrid evaporative warm-mist units that achieve one of the highest levels of energy efficiency among products of their type. The hybrid models are also the industry's only humidifiers for residential applications equipped with a function enabling sequential operation with an air-conditioner(1), and their capacity to prevent excessive room dryness during heating mode operation adds to their appeal.

Among the five fan-powered steam type humidifiers, the two with a humidifying capacity of 350 milliliters per hours (ml/h) consume a maximum of only 250 watts (W) and operate at 27 decibels (dB), making them the most energy-efficient and quietest humidifiers of their type. They also offer superlative operating ease coupled with brightness control of their digital display panel. The fan-powered steam type humidifier lineup also includes two 600ml/h models-the only humidifiers of this capacity offered by the major Japanese manufacturers--and one 1,200ml/h model. Both the 350 and 600ml/h models feature a window enabling easy monitoring of the remaining humidifying water and a fragrance tray permitting aroma therapeutic enjoyment. They come in two color variations: the widely popular pure white and monotone black.

All models in the fan-powered steam humidifier lineup come with a standard-equipped ion filter that curbs scaling, for easy overall maintenance. As with earlier models, they feature "double plasma bacterial removal" functions: one suppresses viruses and airborne bacteria through the release of plasma ions, and the other uses a special filter to capture bacteria and mold(2). The 350 and 600ml/h models also come with retractable handles convenient for carrying the unit, replenishing or removing water, etc.

All fan-powered steam humidifier models adopt a proprietary system in which vaporization is achieved simply by heating the water absorbed by the vaporization cloth, so there is no worry of possible scalding even in the unlikely event the unit were to topple over, as there is no spillage of boiling water. All systems kick in swiftly, requiring only about 1 minute after operation start. Also, because with this type of system humidifying capacity is only marginally affected by ambient temperature or humidity, dependable moisturizing is provided even in low-temperature environments normally difficult to humidify. Maintenance is simple, and an "ECO" operating mode is provided to reduce the humidifying capacity.

The three hybrid evaporative warm-mist humidifier models offer humidifying capacities of 500, 700 and 850ml/h and come equipped with the "double plasma bacterial removal" feature. Hybrid models integrate two vaporizing systems: one in which a moist filter is fanned to induce humidification, the other in which a moist filter is placed in a warm air current generated by a heater to begin humidification. When humidity is low, humidification is achieved swiftly by the latter "warm-mist vaporization" mode; then, when the preset humidity level is reached, the unit switches to the former "vaporization" mode and adjusts the level of humidification. As changeover between the two modes is automatically carried out depending on the humidity level. unnecessary electricity costs can be significantly curbed. When the unit is set to "ECO" operating mode, the heater is shut off and power consumption is reduced by roughly 90% compared to during normal operation.

All hybrid evaporative warm-mist humidifier models are equipped with a function enabling sequential operation with room air-conditioners made by Mitsubishi Heavy Industries Thermal Systems, Ltd.: both the top-of-the-line models in the SRK-S Series (2015 and newer) and the high-performance models in the SRK-R Series (2018 and newer). Employing a humidity sensor on the air-conditioning unit, signals (ON/OFF) are sent to the humidifier to control the preset humidity level. All models of this type also offer superlative ease of maintenance. Their pleated humidifying filter lasts a remarkably long eight seasons (SHK50 model) before replacement is needed, and the standard-equipped silver ion antibacterial agent suppresses water putrefaction and growth of bacteria and mold.
