mission

With its history spanning some 150 years, the Oji Group has cultivated challenging manufacturing based on insight gained from paper making and forest development.

Filter technologies based on wood resources are one such example.

Our mission is to conserve energy and improve air quality.

To shape a livable future, we will harness nature's gifts to provide innovative products.

product 01

Simultaneously achieving ventilation and energy conservation ENERGY RECOVERY VENTILATOR CORE

An Energy Recovery Ventilator CORE is the heart of ventilation equipment.
It collects and reuses indoor coolness and heat to enhance air conditioning efficiency.
ENERGY RECOVERY VENTILATOR CORES have attracted attention as a technology demonstrating ventilation performance and energy conservation simultaneously.

Exclusively developed specialty paper
Striking a balance between high Energy Recovery exchange efficiency and gas barrier properties

This specially developed paper combines high Energy Recovery exchange efficiency with gas barrier properties.
Using the thin specialty paper with high moisture permeability developed from Japan's proud tradition of advanced papermaking technology, it is possible to efficiently reuse the thermal energy of discharged air.

Thin paper processing technology
High-precision corrugated honeycomb structure

Assembling thin paper with a high heat exchange efficiency into a corrugated honeycomb shape is an Oji Group technology.
The high precision of a three-dimensional structure created by layering "divider plates" and "spacing plates" leads to reduced energy costs for air conditioning and conserves energy.

Reassuring track record of adoption
From leading domestic manufacturers to overseas

ENERGY RECOVERY VENTILATOR COREs demonstrate performance in highly airtight spaces such as homes, buildings, schools and hospitals.
The business was launched in 1990.
In recent years, we have produced more than 250,000 units annually and expanded our sales channels in Japan and abroad.

The Mechanism of Energy Recovery Ventilator

Energy Recovery exchange performs the intake of air indoors and the discharge of air outdoors in an intersecting manner.
This makes it possible to replenish the indoor environment with fresh air while maintaining room temperature and humidity.

Research and
Development

With the use of paper processing, the testing, measurement, design and prototyping of the core components of air conditioning equipment and filters for air purifiers and other devices is underway at our research and development sites.
Specifically, we are engaged in the design and development of production equipment.
We develop new products and evaluate performance based on customer needs.
We develop and verify elements that use new materials.
We establish chemical preparations and new formulas.
In conjunction with these activities, we aim to improve the efficiency of quality control and safety management.
