Nippon Medical & Chemical Instruments Co., Ltd. is a manufacturer specialized for environmental control technology.

• The room is maintained at ISO class 6 or 7 (USFDA class 1,000 or 10,000) under positive pressure.
• The room was designed and constructed by introducing a pressure setting damper to maintain the pressure and the function of a draft chamber.
• The temperature and humidity are controlled at 22℃±3℃ and 50％±10％, respectively.
• PARA light is intalled: alarm will be set off in case of abnormal room pressure or temperature.
• The air shower has an interlock on/off mechanism.
• The illumination of MEMS experiment room 1 has a UV shield system.

• An outdoor artificial climate chamber with light shielding day-length treatment system.
• The light shielding device is automatically opened/closed with a time-switch.
• Two metal halide lamps are installed in the light shielding device, which also allows a day-length treatment.
• The temperature and humidity are controlled at 15℃〜40℃ and 55%〜70％, respectively.
• The air flows from the floor to upper walls.

• Six serially mounted artificial climate chamber. Each chamber can be separately controlled.
• The temperature and humidity can be controlled at 5℃〜40℃ and 50%〜85％, respectively.
• CO2 concentration can be controlled betweem an atmospheric CO2 level and 3000 ppm.
• Metal halide lamps are installed, and the number of lighted lamps can be controlled.
• An illuminance of 80,000lx or higher is ensured (at 25℃ and 1.0 cm under the light source).
  

• An infection control exhaust unit with HEPA filters is installed in the room. The air in the room is filtered and cleaned with HEPA filters.
• An infection control exhaust unit has a very compact structure of 300 mm depth.
• A monitoring device is installed.

• The chamber was designed and constructed under a design concept of Multi-Purpose and Multi-Function.
• The temperature and humidity can be controlled at 10℃〜40℃ and 50%〜90％, respectively.
• CO2 concentration can be controlled between an atmospheric CO2 level and 3000 ppm.
• A CO2 gas reducing device is installed, which allows to reduce the CO2 concentration.
• Multi-Lamp system is adopted. Metal halide lamps, twin fluorescent lamps and incandescent lamps are used.
• Special glass is used in the lamp house to take measures for sensible heat load.

High cleanliness is assured to ensure the hospital room to be sterile. The room was fabricated in our factory to save the work load at the hospital. Clean air flows from the top of the bed to under the bed. A shower pan, a hand washer with sterile water, and a toilet are installed in the room.

The animal housing facility consists of anterooms, preparation rooms, and animal housing rooms.
For housing of mice, rats and rabbits, the rooms are kept at positive pressure to prevent air flow from the outside, resulting in ISO class 7 cleanliness level. All fresh system prevents odor from filling the room. No-loss-reheater system can save energy.

The outdoor artificial climate chamber can use natural sun light. Complete prefabrication significantly reduced the installation time, and kept the quality as well. Temperature, humidity, and CO2 concentration are controlled by a program. In case of abnormality, e-mail describing the abnormality shall be sent to the registered address. Not only plant growth or environmental resistance experiments, but also insect ecology or storage experiments can be performed.

The temperature, humidity, illumination, and CO2 concentration can be controlled.
These chambers met the structure criteria of P1P level. To prevent the leak of pollen and the like from the chamber, air is exhausted after filtering through HEPA filers.
Heat-insulated structure and 3 position control allow energy saving.
In the plant acclimation room, 3 in 1 LED illumination is adopted to allow each of RGB to be separately used or combined.
The plant growth chamber has 11 metal halide lamps, which ensure illumination of 70,000 lx.
A remote monitoring system allows you to observe each room.

The two serially mounted artificial climate chamber can control temperature, humidity, illuminance, CO2 concentration, etc.
Experiments can be performed under two environmental conditions at the same time with a program control system.
The chamber has fluorescent lamps and Sunlight lamps, and a reducer that can reduce the CO2 concentration below the atmospheric level, as well. It is suitable for plant growth. This highly-functional artificial climate chamber has been purchase by various universities.

The cell processing room (CPR) consists of a bacteria examination room, a cell culture room, and a storage room. Since the institution deals with hematopoietic stem cells, immunocompetent cells, neoplastic cells, etc., the CPR has a pass room, an anteroom, and the like, and the cleanliness and the pressure level are set based on the required sterility level and risk level in case of contamination.

We designed and constructed the class 1 infection control room for a city hospital.
This room has an autoclave sterilizer for disposing infected wastes and a device for sterilizing infected drainage water.
