Eco multi-heat pump

This is a multi-functional system which employs double band heat pump equipment, allowing two lines to simultaneously take out water ranging from 7℃ to 70℃ in temperature from a single piece of equipment, and which enables highly efficient operation of maximum COP6.3. Further, as this system is driven solely by electricity, it demonstrates significant strengths in terms of both customer ease and safety as well as CO2 reduction measures and measures against sharply increasing energy expenses. Eco multi-heat pumps have been already delivered to various facilities and production factories and are now contributing to energy saving and the preservation of the global environment.

Solar power generation facilities

Solar power generation is a clean and environmentally friendly energy generation system that does not produce carbon dioxide (C02), which is known to cause global warming. Recently, as part of measures being taken for environmental protection, demand from customers to introduce these systems has suddenly increased.
The merits of solar power generation facilities include not having to be selective about a location for the facilities, the comparative ease of maintenance due to the simple structure, and securement of a power source when disasters occur; based on these factors even further introduction of these facilities is expected in the future.
We have been conventionally accumulating know-how for solar power generation from module installation to line linkage system construction. We use construction technology for our current core products, crystalline modules, and what are expected to be core products in the future, thin film based modules. We have established an integrated system in response to customers' needs including subsidy application, planning, design, construction, and aftercare.

ESCO business

The ESCO business provides comprehensive services related to energy saving and contributes to customer profit and preservation of the global environment. By guaranteeing energy savings for the period of this business, we receive monetary compensation equivalent to a portion of the energy saving effectiveness passed on to customers. All costs, such as investment and interest required for energy saving modification, are compensated with the amount of costs reduced due to energy saving. The amount of cost reduction after the end of contract period is pure profit for the customer. The services which we provide may consist of any or all of the following based on meetings with the customer:

In 2006, we participated in an ESCO business for Chokaiso, a public facility run by the government of Yurihonjo City in Akita Prefecture, and for the third sector Foresta Chokai as an EPC (Engineering, Procurement and Construction) company.
This project intends to fully use new energy, save energy, and reduce CO2 by utilizing naturally occurring natural gas for a cogeneration system.

PFI business

We are proactively participating in various PFI projects as a representative special-purpose company in order to achieve the projects' goals, and as a constituent company and/or cooperative company in specialized equipment fields including electricity, air conditioning and hygiene.
