・Ventilation in the cage creates the optimum environment

For some time, our company has paid attention to a laboratory animal breeding

The sales achievement and future development
I’m in charge of the whole process starting from I-rack system’s development and design toproduction, delivery, subsequent performance check and follow-up services. The I-racksystem which came from the unique idea of air-conditioning engineers, has three merits of“environment improvement”, “energy saving” and “enhancement of operability”. This is byhaving good control of air currents. Therefore, we find that the users are very much satisfied
with its high performance. Only about a year has passed since this revolutionary laboratory
animal breeding equipment came out. We will continue to improve the system as well as makeproposals of “the customers’ best” system meeting their needs.

Virtual duct clean room system (VD-CR) achieved with ductless design

We are developing and popularizing various technologies for creating spaces with advanced control functions
like those demanded in the medical field or cutting-edge industries.

Our company has developed a Virtual duct clean room system (VD-CR) which achieves uniform cleanliness in large

The voice of a person in charge of design
We have design teams for electrical facilities, air conditioning facilities, plumbing and sanitary facilities in ourcompany. I am in the plumbing and sanitary facility team and mainly work on designing facilities such as medical
institutions, factories, laboratories, offices and shopping malls.
Required elements in designing vary according to the buildings' use or the clients. We keep in mind to reflectclients' needs accurately on the design as well as taking measures for saving energy and lowering costs, which
are the most requested issues today. This makes it possible for us not only to satisfy the clients’ requests, but toaim at environment-friendly designs.
We should again recognize the great role of architectural equipment in environmental conservation. Instead of justdesigning comfortable spaces for human beings, we would like to willingly propose our original technology suchas the save-energy technology, so that we could offer our clients both an ECO and comfortable space with userand environment-friendly designs.
