Manufacturing energy-saving, precision air conditioners using precise HVAC control technology

We are a proposal-based engineering company with a high level of technological strength in HVAC technology. We have the capability to support integrated manufacturing of HVAC control systems and the energy- saving systems. Our STC air conditioner, for production that requires micrion-order precision, can provide large cooling capacity. It can design a proper air current for air conditioning and build up a stable environment for machinery.

  • Business Outline

    We are a proposal-based engineering company based on a high level of technological strength in HVAC technology which is represented by heat pumps. We have the capability to deal with integrated manufacturing of precise HVAC control systems and energy-saving systems, from planning and design to responsibility for construction. Our company's typical business is integrated manufacturing from the design of specific, precise systems such as an environmental test rooms and temperature test equipment. In addition, we are engaged in the manufacture, sale, and installation of energy-saving, precise air conditioner, as our own products. These products are for production sites where the thermal load is high and fluctuates. We exel in proposals for energy-saving.

  • Product Strength

    Our STC precision air conditioner is a unique air conditioner developed for production sites where micron-order precision is required under a large heat generation load and load fluctuation during precision machining and assembly. This air conditioner stably achieves the best environment for machinery with temperature variation of ±0.2 to 1.0 °C, and offers a large cooling capacity and large volume of air flow to cover a wide area. This is based on our technological strength in designing optimal air circulation. We can also provide energy-saving proposals considering various uses of energy, such as air conditioning and hot-water supplies, based on our highly specialized HVAC and machine technologies and our experience at production sites.

  • Company Strength

    Our company started with a base in technology cultivated during many years of service as an exclusive duty engineer for special business cases of a major equipment construction company. Our motto is to provide a system with high cost effectiveness, based on precise calculations and plenty of experience in the workplace. In addition, our company has a strong capacity to propose proper systems at production sites. This is because we have ample knowledge of heat generation loads and operation conditions of machinery due to our wealth of experience as a precision machine development engineer.

  • Company Structure

    Our company hires people for overseas transactions who have experience working in foreign-affiliated companies and overseas business and we are perfectly prepared to do business in English. We have English brochures.
