Nihon Dengi’s technologies at work around us

Office buildings

Along with an increase in the construction of advanced buildings in recent years, the value of historical buildings has been recognized and their preservation and maintenance (refurbishment) strengthened, leading to a growing demand for air conditioning equipment and energy-saving solutions tailored to the purposes and specifications of each building. In response to these changes in the environment, we provide instrumentation systems that offer the comfort, safety, and eco-friendliness that future generations deserve.

Factories

We are involved in setting up automatic control of production lines for food and pharmaceutical products, thereby supporting not only higher productivity but also safety and quality assurance through the use of various systems. We also propose new solutions such as labor-saving and energy-saving measures that utilize industrial robots.

Hospitals

Hospitals require not only temperature control but also appropriate humidity control for maintaining clean air and preventing nosocomial infections. Operating rooms, in particular, must comply with air conditioning standards and require air conditioning control that utilizes differential pressures for ventilation to improve air quality. Our equipment works around the clock and contributes to the maintenance of healthcare environments for saving lives.

Post offices and newspaper companies

We are involved in setting up automatic control of conveying lines for small packages and newspaper bundles. Advanced automatic control is necessary at distribution sites, where the appropriate conveyance speed and accurate sorting are vital. We have built systems featuring advanced designs by leveraging our engineering experience to cater to a wide range of needs, including the integration of machines from different conveyance equipment in an efficient manner to improve work efficiency.

In addition, Nihon Dengi’s technologies have been utilized in research facilities, cleanrooms, cultural facilities such as museums, and in many other buildings around us.

Did you know? The founding of Nihon Dengi and the origin of its name

Yamatake Keiki Co., Ltd. (now Azbil Corporation) entered into a capital alliance agreement with Honeywell, a leading control equipment manufacturer in the United States, in 1952.
As the import and domestic sale of air conditioning control equipment began in Japan, there was a need for instrumentation work companies to install instrumentation equipment.
Spurred by their belief that the air conditioning instrumentation business would continue to grow, the Company’s founding management team (Shichiryo Shimada and seven others) established Nihon Dengi Co., Ltd., as a company that specializes in air conditioning instrumentation work in 1959.

Origin of company name: The Company was named “Nihon Dengi Co., Ltd.” to reflect its ambition to become the top Japanese company in electric technologies.

What is instrumentation?

Instrumentation refers to technologies that automatically control building equipment to achieve greater comfort, efficiency, labor efficiency, and energy efficiency.

In the case of instrumentation for air conditioning in buildings...

The cycle of “measurement ⇒ monitoring ⇒ control” serves to measure the temperature, humidity, pressure, etc., monitor the measured information by means of computers, and control the facility’s equipment to maintain a certain set of environmental conditions, thereby achieving greater comfort and energy efficiency through control of the entire facility.

Creating an optimal environment through energy-saving solutions (1)Measurement:Conveys on-site conditions to central monitoring equipment via electrical signals. (2)Monitoring:Issues operating instructions to the operating units of facility equipment such as valves, electrically-operated valves, blowers, etc. (3)Control:The results of control operations are measured by sensors to determine if the appropriate temperature, humidity, pressure, etc., have been achieved.

(1) Sensors

Sensors are installed to measure temperature, humidity, pressure, etc., and other variables to be controlled.

(2) Central monitoring equipment

Central monitoring equipment aggregates the information received from sensors in computers. The aggregated information is processed and used to issue commands designed to achieve the optimal environment.

(3) Facility equipment

Valves, electrically-operated valves, and blowers are operated to control the flow of hot/cold water and the amount of electricity accordingly to create an optimal environment.

What is air conditioning instrumentation in the construction industry?

Clients and end users → General contractors (construction companies): Detailed design and construction of buildings → Subcontractors (equipment companies): Detailed design and installation of equipment → Various specialized engineering companies: Detailed design and installation of specialized equipment Instrumentation* (Nihon Dengi) Piping Ducts *Various manufacturers such as Azbil Corporation: Procurement of instrumentation equipment

Did you know? Affiliated parties and Nihon Dengi’s position

For new building automation projects, we receive orders for air conditioning instrumentation work from subcontractors (equipment companies) tasked with the detailed design and installation of equipment. After the building is completed, we are not only tasked with the ongoing maintenance of air conditioning equipment but also receive orders directly from end users (building owners, etc.) for renovation work and support for asset management and asset value enhancement of the building.

For factory automation and process automation projects, we receive orders directly from customers who are primarily end users (manufacturers, etc.). Even after receiving an order, we always follow up with the customer to provide solutions that are tailored to their needs.
