We have developed a PTC immersion heater that has a high-power, fire-free self-temperature control function to replace the conventional nichrome wire heater, and is developing for the usage in humidifier as PTC steam humidifier. We have made it possible only in Japan to install a steam humidifier in the ceiling, which was difficult until now.

The evaporative element (called wet film and media) UC-CORE, which is the main component of the evaporative humidifier, has a laminated structure with strong shape retention and resistance to damage. There is no porous material that takes in odors, and antibacterial and antifungal treatment materials are used that have a low risk of odor generation.

Our ultrasonic humidifiers have double hygiene system called “germicidal device”, which guarantees the absolute safety. We have incorporated the ultraviolet lamp in the water reservoir of ultrasonic humidifier. It is absolutely possible to send out the sterilized air. It exterminates bacteria effectively inside the water of the reservoir by radiation of ultraviolet ray. Furthermore our ultrasonic humidifier is equipped with the automatic drainage system when the unit turns off the power. Its capability to send out the clean humidified air has experimentally recognized.
It has been proven safe in public institutions and is especially effective when used in food-related fields and for human A/C. In addition, the proportional control system was also put into practical use for the first time in the industry.

Drainage vacuum suction device "Drain Sweeper" is a breakthrough device that uses vacuum to "suck" the drain from the air conditioner without concerning about the gradient. It dramatically shortens the drain piping work of air conditioners, and there is no water leakage or large-scale piping cleaning.
